Nest building

Early one May morning in 2019, I disembarked from the ferry in Port aux Basques, Newfoundland, bewildered and discombobulated from too many days of long-distance driving and too little sleep. The previous evening, I had left continental North America behind; however, I still had a long way to go before reaching my new home in St. John’s.

The route from Port aux Basques to St. John’s.

Back when I started planning my inter-provincial move, it seemed an entirely reasonable proposition make the 900 km drive from one end of Newfoundland to the other in a day. Blinking in the cold, salty ocean air that morning, I wasn’t quite as sure. But turning around wasn’t an option, so I filled my travel mug with coffee and climbed back into my car.

However, as the day wore on, it became clear to me that I had severely underestimated the size of my new home. By early afternoon, I was barely at Grand Falls-Windsor (town motto: “Perfectly Centered”). Many hours later, I crossed onto the Avalon Peninsula – only to find an impenetrable fog blanketing the highway. I gripped the wheel a bit tighter as my mind filled with images of moose lunging suddenly into the path of my car.

The sun had long since set by the time I drove into St. John’s. All day, as my tires ate up the miles, my panic had also been ratcheting up. I had moved to Newfoundland to coordinate a breeding bird atlas – a massive citizen science initiative to inventory all the bird species breeding on the island. But as I drove…and drove…and drove…I couldn’t help but think, “We have to atlas all this?”

A very different view.

And my panic went deeper than that. The scraggly fir and spruce trees and quiet waterways scrolling uninterrupted past my window were very different to the deciduous trees, crop fields, and suburbs of southeastern Ontario. The landscape felt very alien, and I felt very out of my depth. It seemed impossible that this place would ever be home.

***

If left to my own devices, I might never have left my apartment. But I had moved to Newfoundland to do a job, and part of that job involved learning what fieldwork in Newfoundland was like. If we were going to ask citizen scientists to brave the island’s bogs, forests, and windswept cliffs, it seemed only fair to understand what we were asking of them.

Where’s Waldo?

And so, less than a month after arriving, I found myself setting up camp on a small island off the north coast, spending my days plunging my arm into underground burrows, groping blindly for Leach’s storm petrels, and my nights untangling them from mist nets by the dozens. A few weeks after that, I perched on the edge of a precipice at Cape St. Mary’s, staring at northern gannet nests until my eyes crossed and my vision blurred. (Magic eye pictures are nothing compared to trying to find a particular nest among hundreds packed onto a rock ledge.) And shortly after that, I was in a helicopter, heading out to the rugged backcountry of Gros Morne National Park.

***

Yup.

And suddenly a year had passed, and I found myself right back where I started. After a long day on the road, my car was suddenly encased in fog. Between the dark and the dense air, it was impossible to see more than a few meters ahead; I crept along at a snail’s pace just in case a moose suddenly got the urge to cross the road. Our headlights lit up two words painted onto a rock by the side of the road: “Fog off”. I couldn’t have agreed more.

The parallels were striking. But over the year, many things had changed

“You know, it’s a mistake to think of Newfoundland as a terrestrial place,” said my friend from the passenger seat. “It’s half marine, at least at times like now. That fog? That’s the ocean paying us a visit.” I couldn’t decide whether that made the fog more benign or less.

My friend and I were on the first leg of an epic journey to survey for birds in some of the farthest flung places on the island. In planning for the trip, we decided to target locations citizen scientists would be unlikely to get to. In other words, we picked a few peninsulas and followed them right to the end.

A perfect day for a dip in the ocean.

And so my second summer in Newfoundland consisted of exploring some of the small towns, dirt roads, and hidden gems of the island’s interior, serenaded by the omnipresent “Oh-sweet-Canada-Canada-Canada” of white-throated sparrows. From an ocean dip in St. Alban’s, to the best ice cream I’ve ever tasted in Grand Falls-Windsor (they should put that in their town motto!), to exploring an enchanted little park in Summerford, it was the kind of trip that can make you fall in love with a place.

I’ve often said that fieldwork offers a unique opportunity to get to know a landscape. But I don’t think I realized just how true that is until I moved here. Over the last year and a half, fieldwork has given me the means and opportunity to get out and explore this windy, foggy, magical island. Newfoundland still isn’t home to me, but it no longer feels impossible that one day it might be. And in the meantime, I can’t wait to get back out there next summer and explore some more.

How do you solve a problem like migration?

This post was initially published on the Science Borealis blog on April 27th, 2020. Check out their blog for more great science stories, published every Monday!

I can feel the rapid thrumming of the bluebird’s heart against my palm as I carefully manoeuvre its foot into position over a tiny Ziploc bag. I pick up my nail scissors and take a deep breath to steady my hand. I will only get one chance to make sure the miniscule claw clipping lands in the bag. If it doesn’t, I will have no chance of finding it…and no way to discover where this bird spent the winter.

Field biology often requires unusual skills. I have spent the last decade becoming an experienced bird pedicurist, because analyzing the chemical composition of tissues like claws and feathers is one method scientists use to determine the movements of migratory animals.

Unfortunately, this method suffers from the same drawback as many others: a lack of precision. As a result, many aspects of bird migration remain a mystery. But this spring, researchers at the Max Planck Institute of Animal Behaviour in Germany are entering the final testing phase of a new space-based tracking system, which they hope will revolutionize our understanding of animal movement.

The puzzle of migration

For Canadians across the country, the return of our migratory birds marks the beginning of spring. Each year, 2.6 billion birds cross the Canada-U.S. border, heading north to their breeding grounds.

Two thousand years ago, Aristotle believed the spring reappearance of barn swallows meant they were emerging from their winter hibernation at the bottom of ponds. Although we now understand more about animal migration, many questions remain – largely because it’s very difficult to track individual animals as they travel vast distances around the globe.

For many years, the only approach was to mark animals with bands or tags in the hopes of re-sighting them somewhere else. But the sheer number of animals that migrate makes seeing a marked individual again extremely unlikely.

Putting the pieces together

In the 1990s, migration research took a leap forward when scientists realized the chemical composition of animal tissue reflected the place where it was grown. By analyzing the ratio of various isotopes in tissue (termed stable isotope analysis), researchers can roughly reconstruct an animal’s geographic history…which is why I found myself giving bluebird pedicures.

Scientists can also now track moving animals directly by fitting them with tags that record location. These tags can be divided into two broad categories. Archival tags, such as geolocators, record and store movement information. In order to find out where a tagged animal has been, researchers must recapture it and retrieve the tag.

Recapturing migratory animals often proves difficult, especially as many fail to return from migration. So when possible, researchers prefer to use tags that remotely transmit data to a receiver, eliminating the need to recover them.

But transmitting tags face a fundamental constraint: transmitting takes power, and the more power a tag requires, the larger it needs to be. Tags must weigh less than 5% of an animal’s body weight to avoid affecting its behaviour or survival. Considering that many migratory birds weigh less than 10 grams, making tags small enough for them to carry is a huge challenge.

The amount of power required to transmit data depends largely on where the receivers are. Tags for ground-based tracking systems – with receivers located on the Earth’s surface – can be very small. For example, the nanotags used by the Motus Wildlife Tracking System range from 0.2 to 2.6 grams, and can even be carried by some large insects. However, the range over which ground-based systems can track individuals is limited. Animals carrying Motus tags can only be detected within approximately 15 km of a receiver.

In contrast, satellite tags send data to receivers on orbiting satellites. They can track movement at a much larger scale than ground-based systems, and have been used for years on big animals, such as seabirds and caribou. But most satellite tags are too heavy for small migratory birds.

The Icarus Initiative

In 2007, Martin Wikelski, the Director of the Max Planck Institute of Animal Behaviour in Germany, proposed a novel space-based system for tracking animals across the globe.

It took more than 10 years, and the cooperation of the Russian Space Agency (Roskosmos) and the German Aerospace Centre (DLR), for the system to become a reality. In March 2020, the International Cooperation for Animal Research Using Space (Icarus) entered its final testing phase. The first Icarus tags are waiting to be shipped to researchers, and the system will be available to the scientific community this fall.

“We wanted to build [a tracking system] specifically for wildlife,” Wikelski says of Icarus. “It’s built by the community, for the community.”

Icarus tackles the trade-off between tag size and transmission distance in part by the simple expedient of moving the receiver closer. Conventional satellite tags transmit their data to Argos satellites, which orbit the poles at an altitude of 850 km. Icarus tags will transmit their data to a receiver on the International Space Station (ISS), orbiting at an average altitude of 400 km.

Data collected by Icarus will be stored in Movebank, a free online database accessible by the public.  The system will also incorporate a citizen science initiative: Animal Tracker. While Icarus tags tell scientists where an animal is, citizen scientists can provide information about what it’s doing there. Using the Animal Tracker app, people can follow tagged animals online, and anyone who spots those animals in the wild can submit their observations to the database.

Of course, like any tracking system, Icarus will have some limitations, at least initially. The first tags will weigh five grams, which – while smaller than many satellite tags – is still too heavy for most migratory birds. However, the design of a new generation of tags weighing only one gram is already underway.

Satellite coverage will also be an issue. The receiver on the ISS will be able to pick up signals from most of the Earth’s surface; however, high latitude regions in the north and south will not be covered. Eventually, Wikelski’s goal is to deploy dedicated Icarus satellites strategically to cover the entire globe.

But even with these limitations, scientists are eager to begin harnessing the power of Icarus to tackle some of the unsolved mysteries of migration. Dr. Kevin Fraser, an Assistant Professor in the Department of Biological Sciences at the University of Manitoba, is keenly awaiting his first shipment of tags. He and his graduate students plan to put them on saw-whet owls – and they are most interested in the birds that don’t come back in the spring.

Fraser’s previous research has largely depended on archival tags, meaning tagged birds must be recaptured to determine where they went. Individuals that don’t return to the study sites to breed – those that die along the way, or the young birds that disperse to breed elsewhere – are lost data.

“Most of what we know about migration, we know from birds that have successfully migrated,” Fraser says. “We know much less about where survival might be limited, or what the juveniles are doing. But [with Icarus], for the first time, we will be able to track 100 gram birds (the smallest yet) in near real-time, without the bias of only focusing on survivors and adults.”

Solving the puzzle

With the sliver of claw safely stowed in a bag for later analysis, I’m ready to liberate my captive bluebird. I position its feet over my empty hand and release my hold. For a moment, it perches on my palm, apparently unaware of its freedom…then, in a flutter of wings, it’s gone.

Of the 450 bird species found in Canada, 78% spend at least part of the year outside our borders. This fall, four billion birds will cross our southern border to spend the winter in warmer climes. More than a billion of them will not return, succumbing to the dangers of the journey or the hazards of their wintering grounds.

Icarus offers us a unique window into the world of migratory birds, and a chance to improve their odds. If we know where they go and how they get there, we can begin to understand the perils they face – and perhaps develop solutions.

Battle scars

It will come as no surprise to anyone familiar with the academic world that academics don’t always agree. In fact, they often engage in fierce and lengthy disagreements about topics that never cross the minds of 99% of the world’s population.

These disagreements are the foundation of good science. Good science happens when smart people with different ideas engage with each other and find ways to test those ideas. However, if you’re a field assistant for one of those smart people, those disagreements can also be a pain in the ass.

An argument between two scientists is exactly how I ended up crouching in the middle of a patch of poison oak in the California hills, my fingers stuffed in my ears, tensed in anticipation of a shotgun blast. (But it’s not quite as bad as it sounds – I promise no scientists were harmed in the making of this blog post!)

At the time, I was working in California for a professor who had been studying acorn woodpeckers for many years. Acorn woodpeckers, as their name suggests, depend heavily on acorns. In fact, groups of these birds create ‘granaries’ by drilling holes in trees (or anything else, including people’s houses) and stuffing those holes full of acorns for later consumption.

Given the tight ties between the woodpeckers and their food source, it made sense that the professor I worked for was interested not just in the birds, but also in the oak trees they relied on – in figuring out the details of how and when they produced their acorns. And this was the source of the argument I found myself in the middle of.

My boss had gotten into a disagreement with another scientist about how far oak pollen could travel. The question was whether oak trees could be pollinated only by other oaks within a relatively small radius (roughly a kilometre), or whether the pollen could travel much longer distances. The funny thing is, I honestly can’t remember which side of the disagreement my boss was on; all I know is that he had decided he was going to settle the question once and for all. How, you might ask? Well, that’s where the shotgun came in.

The logical thing to do, he had decided, was pick a focal oak tree and take a leaf sample from every other oak within a 1 km radius. Then he could sample the focal tree’s acorns and try to match them to DNA from the leaves of the putative fathers – a plant paternity test.  If he found that at least some of the acorns did not belong to any of the trees he had sampled, he would have evidence that pollen could travel farther than a kilometre.

However, this plan turned out to be anything but simple in its execution. First of all, the field station was surrounded by oak savannah.  By definition, there were a *lot* of oak trees around. Sampling every oak within a kilometre of the chosen focal tree was not a trivial task.

The landscape around the field station: rolling hills covered with – you guessed it – oaks.

Second, many of those oaks were located in…inconvenient…places, such as at the top of steep hills, the bottom of ravines, and often, the middle of large patches of poison oak. Closely related to poison ivy, poison oak is – as its name suggests – a plant better avoided. Its leaves are covered in urushiol, an oil which causes an allergic reaction in the majority of people who come into contact with it. My boss informed me that he was in the lucky minority that did not react to it. Never having encountered poison oak before this field job, I didn’t know which camp I fell into, but I wasn’t really interested in finding out the hard way.

Third, most of the oaks we wanted to sample were beautiful, stately, tall old trees. Their height was obviously an advantage when it came to spreading pollen – but a substantial disadvantage when it came to getting a DNA sample.  Plucking a leaf from a 25 m tall tree is easier said than done…which brings us back to the shotgun.

If we were unable to reach a tree’s leaves, my boss’ plan was simply to shoot a twig off. Then the twig and its attached leaves would float down to the ground, allowing us to waltz over and pick up the sample with minimal effort.

Presumably several potential flaws in this plan are obvious to many of you.  But for me, the main problem wasn’t my boss’ aim (as you might think) – but rather the noise associated with shooting our samples down. As someone with a phobia of sudden loud noises (it’s a thing, really!), I can’t even be in the same room as a balloon…so shotgun blasts are well outside of my comfort level.

Eventually, my boss and I worked out a routine. After hiking, scrambling, or clawing our way up (or down) to the tree we were trying to sample, we would circle it (often wading through swaths of poison oak) to look for any leaves within reach. If we didn’t find any, he would get out the shotgun and start sizing up targets, while I would retreat, crouch on the ground, stuff my fingers as far as possible into my ears, and wait for the bang.

By the time we wrapped up at the end of the day, my ears were ringing and my fingers hurt from spending a substantial portion of the day crammed into my ears. Shortly after getting home, I discovered that yes, indeed, I did react to poison oak.

And to this day, I still don’t know how far oak pollen can travel.

4 reasons I shouldn’t be a field biologist

My lungs are bursting as I stumble to a halt, slipping on melting snow crystals.  Squinting against the glare, I lift my head – and immediately wish I hadn’t.  Behind me, a vertigo-inducing slope of snow drops away.  In front of me, the sight is even worse: the slope continues up…up…up.  At the top, four figures stand waiting impatiently.  It’s clear that I’m hopelessly outclassed. As I force myself to start climbing again, I can’t help but wonder: is it too late for a career change?

***

I guess I should back up and explain how I got myself into this situation.  When I finished my PhD, I had a singular goal: I wanted to continue doing fieldwork and research.  So when Bird Studies Canada offered me a job coordinating Newfoundland’s first Breeding Bird Atlas, it seemed like the perfect opportunity.

Breeding Bird Atlases (BBAs) are ambitious projects that aim to map the distribution and abundance of all birds breeding in a province or state over a 5-year period.  Every Canadian province except Newfoundland has (or is in the midst of producing) at least one BBA.  The end product allows us to better understand the health and distribution of bird populations and can be used as a tool for conservation planning.

Most atlas data is collected by volunteer citizen scientists, making atlases a great forum for community engagement.  But once in a while, the coordinator is lucky enough to get out into the field too.  And when the opportunity presented itself to do some pilot surveys in the remote regions of Gros Morne National Park…how could I say no?

A rainbow stretches across the green hills of Gros Morne.

A rainbow stretches across the green hills of Gros Morne.

I drove into Gros Morne under a spectacular rainbow, arcing across hills and lakes of the park.  It seemed like a good omen.  And although a few days of weather delays frayed our patience a bit, finally the skies cleared and we climbed into a helicopter for our flight to the top of Big Level, one of the highest points in the park.  As we swooped over Western Brook Pond, Gros Morne’s famous freshwater fjord, I couldn’t wait to get started.

We descended into an alien landscape: the arctic-alpine habitat found in only few places in Newfoundland.  For a few hours, we wandered under the widest blue sky imaginable, exclaiming when we crossed paths with an enormous arctic hare and enjoying the silvery sound of horned lark song.

But then we started our hike towards the cabin where we’d be staying the next few nights.  And once we were on the move, the evidence that I was way out of my depth accumulated rapidly.

Pausing to take a picture is a great excuse to catch your breath an on strenuous hike…

I’m a fairly active person, and I thought I was in reasonable shape…until I spent a day trailing four people (all with a distinct resemblance to gazelles) across tundra, snow, and bogs.  As the warthog among gazelles, I was also the most likely to plunge without warning through the crust of snow we were walking on, landing with a thump in whatever was below.  With each minute, I lagged farther and farther behind.

My problems were compounded by my short legs and terrible balance, which resulted in me frequently tripping over rocks, trees, and my own feet – not to mention being unable to cross many of the streams my gazelle companions leapt over easily.

Reasons #1 and 2: Warthogs aren’t made for long-distance hikes involving lots of climbs.  Short legs and poor balance don’t help either.

By the time we made it to the cabin – after a solid eight hours of hiking – I was beyond done.  I collapsed on the cabin deck, and I might still be there, if some kind soul hadn’t provided incentive to get up in the form of a cold beer.

I told myself the next morning would be a fresh start.  But when the alarm sounded at 4:30 and I rolled my aching body out of bed, I realized I had overlooked another reason I’m not cut out to be field biologist – or at least an ornithologist.

Reason #3: As documented in previous posts, I’m very much not a morning person.

But birds start the day early, so we had to as well.  Our plan was to conduct 8 to 10 point counts each morning.  A point count involves standing in one place for a set amount of time (in this case, 5 minutes), and documenting every bird seen or heard.  Sounds straightforward, right?  But because birds are more often heard than seen, point counts require sharp ears and an encyclopedic knowledge of bird song.

As we climbed a steep hill to our first point, all I could hear was my own panting.  I managed to catch my breath when we stopped to conduct the count…only to become aware of yet another problem.

Reason #4: I don’t know enough bird songs.

I could recognize some of what we heard, but definitely not all of it.  I especially struggled with the partial songs and quiet ‘chip’ notes that were often all we heard.  Luckily I was with several spectacularly talented birders, who were more than capable of conducting the counts.  But after a few days in the field, I was feeling pretty discouraged.

And then on our last day, we came across a(nother) sound I hadn’t heard before: a single repetitive note, like the alarm on a tiny car.  We tracked the sound to a nearby conifer.  Perched at the very top, staggering as the tree swayed, was a greater yellowlegs.

Shorebird in trees look undeniably ridiculous.  Gawky and awkward, the yellowlegs scrabbled constantly for balance as it fought to stay on its perch.  It was impossible to watch without laughing…and I began to feel better.

A greater yellowlegs perches at the very top of a conifer.

Some birds just aren’t meant to perch in trees. But this greater yellowlegs isn’t letting that bother him.

Shorebirds aren’t built to perch at the top of trees, but the yellowlegs was there anyway.  And now that my first atlassing excursion is over, I’ve reached a conclusion.  Maybe I’m not naturally suited to this job.  It certainly doesn’t always come easily to me.  But the things I don’t know, I can learn; the things I struggle with, I’ll improve at with practice.  What matters is to be out there trying.

It’s true there are many reasons I’m not cut out to be a field biologist…but there’s one reason I am: doing this job makes me feel alive.  And for me, that cancels out everything else.

Cloudy with a chance of data

Anyone who does fieldwork knows how important the weather is.  Regardless of what you study, the weather plays a huge role in shaping the kind of day you have.  It determines if you go home at night thinking you have the best job in the world, or wondering why any sane person would do what you do.

So much for the rain day: checking tree swallow nest boxes in the rain.

So much for the rain day: checking tree swallow nest boxes in the rain.

When I started my first field job, my boss told me firmly, “Birds don’t do anything in the rain.”  This is a maxim most of us ornithologists cling to – because it means that there’s no point in us going out in the rain.  And as a field assistant, I deeply resented it when the desperate graduate students I worked for sent me out in the rain anyway.

I always thought I’d be the first to call a rain day and take a well-deserved break from fieldwork – until I became one of those desperate graduate students.  Then I realized what my former bosses had known all along: while you may not be able to catch birds during a rainstorm, losing an entire day of data collection isn’t an option either.

There are a number of strategies to try and wring some data out of a rain day, most of which involve sitting in the car at your field site, hoping for a break in the weather.  The strategy I employed during my PhD fieldwork in British Columbia was based on this approach, but with an added twist.  Because my sites were spread over 100 km of the southern Okanagan Valley, even when it was raining at one site, it might be clear at another – at least in theory.

Chasing the rare patch of blue sky on a rainy day in the Okanagan Valley.

Chasing the rare patch of blue sky on a rainy day in the Okanagan Valley.

In practice, this amounted to something very similar to chasing the end of a rainbow.  We spent many days in the field driving back and forth between sites, in the (largely futile) hope of being in the right place at the right time to catch five minutes of blue sky.  It almost never worked…and I’m sure my field assistants felt the same way about me as I had about my former bosses.

Sometimes, of course, there’s just no way to avoid bad weather. This is particularly true if you happen to be doing fieldwork on a small island – like the summer I worked for a friend catching terns on Lake Winnipeg, Manitoba.

Impending doom: a storm approaching across Lake Winnipeg.

Impending doom: a storm approaches across Lake Winnipeg.

On this particular day, I had been glancing nervously at the sky for over an hour, getting increasingly anxious as towering clouds approached from across the lake.  Rather unfortunately for a field biologist, I hate sudden loud noises (like thunder), so I was quite vocal about my desire to get the hell off the island before the storm hit.  But my friend – who was also my boss for those two weeks – was determined to squeeze every possible moment of data collection out of the day.  She repeatedly insisted the storm would probably miss the island entirely.

Needless to say, it did not.  When the downpour started, she was sitting in a nylon blind in the middle of the tern colony.  I, on the other hand, was out on the beach – I’d finished the task she’d sent me to do, but couldn’t return to the blind without disturbing the birds she was trying to catch.  As the rain poured down in buckets and the thunder shook the island, I looked desperately for someplace – any place – to shelter.  But there was nothing except the slate gray water of the lake and the dirty sand of the island.  There was nowhere to go.

Finally, I resigned myself to my fate.  I sat down cross-legged on the beach, stuffed in ear plugs, and covered my ears with my hands for good measure.  For the next hour, I stayed in exactly the same spot on that beach, getting wetter and wetter and more and more miserable.

By the time the storm finally moved off, every item of clothing I had on was completely soaked. As I stood up, water cascading off my jacket, my radio went off.  It was my (completely dry) friend, asking me to move on to the next task on our to-do list.  (This is a great example of why it’s often a bad idea to work for friends/family/significant others in the field: homicidal rage tends to be bad for any relationship.)

But of all the places I’ve done field work, the site that wins the title for the worst weather is Sable Island.  As anyone who’s lived in eastern Canada knows, the Maritimes are a place you love in spite of – not because of – the weather.  Sable, a thin crescent of sand approximately 150 km off the coast of Nova Scotia, is no exception.  It is frequently shrouded by fog, which has undoubtedly contributed to its reputation as the “graveyard of the Atlantic”: the site of more than 350 shipwrecks over the past 450 years.  In fact, the summer record for fog on Sable is 30 days in June and 31 days in July.

When I arrived on Sable, I figured the island’s Environment Canada meteorological station – located approximately 50 steps from my front door – would be a major advantage of working there.  Instead of checking the forecast online, I could get my information straight from the source.  So the very first day I woke to the patter of rain on the roof, I headed over to the station.

I ducked inside, shaking water droplets off my coat, to see two people staring intently at computers, the very picture of hard work.  “So,” I asked, trying to sound casual and not thoroughly panicked by the very long to-do list the weather was interfering with, “How long is this rain going to last?”

Both meteorologists looked up from their computers, blinking fuzzily at me.  Clearly I had caught them off guard.  (You don’t tend to see many people working on Sable Island.)  But they weren’t nearly as surprised by my presence as I was by their reply.

“How the hell should we know?”

The challenges and joys of being a parent in the field

This week, Dispatches from the Field welcomes Dr. Tara Imlay, a recent PhD graduate, swallow conservation expert, and parent. In her post, Tara shares some of the challenges of this kind of multi-tasking – as well as some of its rewards. For more about Tara, see her bio at the end of the post.

Just call me Dr. Mama… after all, my precocious nearly three-year-old does.

Field work was one of my primary considerations when I chose to have a baby during my doctoral degree.  Specifically, I wanted to avoid being in the third trimester during my second field season, and I wanted the baby to be at least six months old during my third field season.  As you can imagine, that left a very small window in which to get pregnant.

Luckily, for me, that wasn’t a big challenge.

Instead, the challenges during my second field season came in the form of prolonged morning sickness, food aversions, exhaustion, and changes to my centre of gravity.  The latter landed me in the hospital after I fell over a bank one morning while mist-netting Bank Swallows.  Luckily, no one was seriously injured – and one of my field assistants now has an amazing response to any interview questions about dealing with unexpected problems in the field!  After that experience, though, I began delegating a lot more field work to my assistants, especially anything involving heights.

The challenges in my third field season came in the form of exhaustion from lack of sleep.  At that time, Robin* was still waking up routinely through the night for feedings.  On numerous nights, she was up at 11, again at 2, and my alarm would go off at 3.  Honestly, I don’t remember a lot of the details of that field season, but somehow we managed to get everything done.

But despite the challenges, there were a lot of amazing moments during those field seasons and the field seasons since.

Moments like sitting in the field banding birds, with a very chubby baby propped up beside me.  Or watching how excited she got over seeing all the birds, cows, sheep, dogs, and anything else that moved at my field sites.

This past year, she’s taken on a more helpful bent in the field: carrying equipment, checking swallow nests, and, her favourite task of all… getting to let birds go after they’ve been captured and banded.

This doesn’t mean everything is perfect.  Sometimes, it’s a challenge to manage her short attention spans, and I can’t always bring her with me when I’m in the field.  Luckily, I’ve had the opportunity to work with several great people who don’t mind helping out with an inquisitive child, when needed.

But despite the challenges, having a baby during my PhD didn’t affect my ability to finish my degree, and hasn’t stopped me from pursuing other opportunities, both in and out of the field.  Becoming a parent with a busy field schedule isn’t a common occurrence, but if it’s something you want, then you just have to go for it, deal with the challenges as they come, and enjoy the special moments along the way.

No Exit

“Hell is other people” – or so said French philosopher Jean-Paul Sartre.  Sometimes I can’t help but think Sartre must have been working as a field biologist when he wrote that.

Sartre’s quote is frequently misinterpreted: he wasn’t saying that other people are terrible beings who should be avoided at all costs.  Rather (at least, as I understand it), he meant that hell is always being in the presence of other people – inescapably watched, and therefore inevitably judged, by those other people.

Most people who have worked at remote field sites would recognize that claustrophobic feeling, at least to some extent.  When you’re in the field, you put in 14 hour days with your co-workers – only to go home, have dinner with them, and then hang out together until it’s time for bed.  When you wake up in the morning, you do the whole thing over again.  There’s no escape: you work, live, and sleep with the same people.  No matter how fantastic those people are, it gets wearing.

And of course, when you are always with the same people, it is inevitable that some of their habits will rub you the wrong way.  At first, it might just be a minor annoyance – a bit like the slightly irritating tag in your jeans that you keep meaning to cut off.  But when you’re in the position of wearing those jeans all day, every day, for months on end, that slightly irritating tag eventually becomes almost intolerable.

After many field seasons at many different sites, I can definitely say that I’ve experienced my fair share of interpersonal drama.  For example, one of my field jobs involved working at an isolated field station, which I shared with only five other people.  A group of six people doesn’t provide all that many conversational options under the best of circumstances – but things get a whole lot more awkward when three of those people aren’t speaking to the other three.

You don’t really know someone until you’ve spent hours sitting in a 2 m-squared blind with them, waiting to catch trap-shy birds.

But despite the interpersonal drama that is almost always part and parcel of the experience, I maintain that other people are often the best part of field work.  I’ve heard it said that only your siblings can understand your family’s unique brand of craziness; in the same way, only people you make it through a field season with can really understand the insanity you both survived.  Adversity has a way of creating strong bonds, and most field seasons involve enough adversity to produce some pretty robust adhesive!   Your field colleagues are the ones who bang on your door at 4 am when your alarm doesn’t go off, and the people who share your bouts of hysterical laughter about something (or nothing) when too little sleep and too much stress take their toll.

Too many early mornings are more tolerable when you have someone to complain with!

But it’s more than that.  My blog posts for Dispatches frequently focus on the importance of place – but most of the time, it’s the people who make a place.  My memories of the amazing places I’ve worked are inextricably intertwined with the amazing people that I shared those places with.  And while I’d love the chance to go back to visit some of those field sites, I know they wouldn’t be the same.

Ultimately, the people you share a field season with are the ones who experience in all the frustrations and triumphs of that field season right along with you.  And as we all know, both frustration and triumph are so much better when shared.

And hey – if all else fails, your field colleagues at least provide a measure of protection against bears…as long as you can run faster than them.  🙂

The birds and the bees

This week, Dispatches from the Field is excited to welcome Alannah Gallo. Alannah got her start in environmental consulting over the summer, and shares some of her adventures surveying both avifauna and pollinators in western Canada.

As I write this, I am about to land in Winnipeg, Manitoba, for my last round of pollinator surveys of the year…and I’m so relieved I’ve made it through the field season.

These past few months have been my first exposure to field work. I was fortunate to have two employers willing to share me as I worked on bird surveys for one company, and pollinator surveys for the other. Working two very different jobs at the same time and the huge learning curve that came with both was a lot to take on, but I’m so happy I did. In my bird survey position, I was fortunate to have an amazing and supportive set of coworkers to help me become a better birder. The pollination surveys, though, were a bit more challenging, as I was completely on my own for all the travelling, planning, and surveying I had to do from June to September.

A pollinator visits one of the flowers grown from our seed mixes.

The objective of Operation Pollinator was to measure the effect of pollinator seed mixes on pollinator diversity. Seed mixes were sent to landowners in Northern Alberta, Manitoba, and Saskatchewan who would plant them in sites they had set aside for the project. The idea is that I would have an initial meeting with the landowners, who would show me where they had planted the seed mixes, and then I would visit these sites, along with a control site (i.e., an area where no seed mix was planted), once a month from June to September to survey for pollinator diversity and abundance. There were five pollinator sites and one control in each province, for a total of 18 sites…so it was a lot to handle.

The process of surveying for pollinators is fairly straight forward. I placed pan traps, which are plastic yellow or white bowls filled with water and soap, along transects and waited for insects to fly in. (This works because pollinators are attracted to the colours yellow, and white). I also conducted net sweeps, using a bug net to sweep through the vegetation at each site. Finally, I did visual surveys – in other words, I watched what species visited the flowers from the seed mixes.

A common alpine butterfly captured during a net sweep.

When I got the job, it sounded totally manageable. I was eager to prove myself and set out to do what I could to prepare myself for the field work. I first studied pollinators during my undergraduate degree at the University of Calgary, where I took courses on invertebrates and entomology. Then I volunteered with John Swann, the curator of the Entomology Museum at the University of Calgary , who trained me to process and identify specimens. (One of the best things I learned from this training was how to fluff bumblebees – probably one of my favourite things to do!) Once I got the pollinator survey job, I refreshed my knowledge by reading up on the most common species of pollinator in western Canada and creating flashcards for the flowers I was told to focus on when at each of my field sites. I thought I was decently prepared, and ready to tackle this project.

I was so, so, wrong.

Identifying insects in the field was so much more difficult than I had anticipated. Insects at the museum were pinned and sat still, allowing me to focus, use my reference texts, and take my time. Insects in the field…not so much. I had to adapt quickly. Each month also came with a new set of organisms to ID, as both the flowers and the pollinators changed with the season. On top of that, although there was overlap, the biomes of the sites varied significantly across the provinces. In the end, I basically had to re-learn and memorize everything there was to know about pollinators…over, and over, and over again. During each day of surveying I would take photos or sketch doodles of the species I didn’t know and figure out what they were at night in my hotel. Then the next day, I would have to wake up and continue to my next sites. It was exhausting, but so rewarding.

One of my favourite memories of this summer took place at one particularly beautiful (and terribly tick infested) forested site near Erickson, Manitoba in June. I had laid out my pan traps and was waiting for whatever was in the area to land in them while I conducted my visual survey. After a few minutes, I checked on my traps and was surprised to see that a beautiful Canadian tiger swallowtail (Papilio canadensis) had been attracted by the colour of the pan trap and fallen inside. I quickly reached in to pull it out, but saw that my trap had soaked and damaged its wings. It needed a safe place to rest while it dried out…so I placed the butterfly on my arm, and it sat there while I continued my work for the next 20 or so minutes. Slowly, its wings dried, and eventually I placed it in some nearby clover. At that point, it was able to fly short distances, so I hope it was okay in the end.

I’ve come so far in four months, and I now have a much better feel for wildflowers and insects in Alberta, Saskatchewan and Manitoba. Considering how much I had to deal with, between managing life and working two consulting positions, I’m immensely proud of myself for handling it so well. I want to continue to pursue work in the consulting field, and so I need to become proficient at identifying birds, bees and plants. It’s an exciting journey, and I can’t wait to tackle more work next season and continue to push myself to learn and become an excellent naturalist.

It’s not just a ditch

This week, Dispatches from the Field is excited to welcome Dr. Melanie Kingsbury as a guest poster.  Melanie has done fieldwork on lakes in Canada and the UK…but today she tells us about her experience working in an urban development.  For more about Melanie, check out her bio at the end of this post.

Over the past 16 years I have had the opportunity to undertake field work in several interesting places. Some of them were local, such as Big Rideau Lake, and some of them were much harder to access – such as the boreal lakes of northwestern Ontario, where access involved driving down logging roads and hiking down trails with equipment. More recently, my research has taken me to lochs located on the archipelagos of Shetland and Orkney, which was an amazing experience. But the most unique experience I have had doing fieldwork was working in the ‘wilds’ of a large urban expansion project in the mid 2000s. We were tasked with monitoring the streams and urban ponds in the area being developed, which was originally farmland.

One of the streams we monitored, right beside houses under construction.

Some highlights of working in an urbanizing environment include:

* Walking around new, upscale neighbourhoods to gain access to the urban ponds and streams, looking sorely out of place in chest waders carrying various pieces of sampling gear. We got even stranger looks when our gear included carrying a canoe…or sitting in the middle of a pond in one (I am surprised that the police were never called with such suspicious behaviour);

* Waiting for dump trucks, heavy machinery and cars to go by so we could cross roads and active construction sites to get to sampling locations, all the while decked out in said gear;

* Discovering urban ponds full of goldfish or watching house painters rinsing paint brushes in them.  (When we spoke to the painters, they responded, “They are just storm water ponds,”…implying an extension of the street drainage;

* Coming face to face with giant hogweed for the first time, scattered around a grove (they had not taken over yet) at one of our sampling sites. It looked like the setting for a twisted fairy tale with these 2 m high plants with large leaves towering over us;

*Walking through a municipal building in field clothes to get to the roof to download the rain gauge located there;

* Discovering one day that our stream site containing a data logger had been completely re-graded and the stream rerouted. By the time we found out, it was in the middle of summer and we were presented with a bare rolling landscape (no grass had been planted yet), with stakes to mark the new path of the stream. We never did recover the logger. My guess is that it is still recording (soil temperature at least) to this day, somewhere underneath the dog park that exists there now;

* Experiencing the luxury of driving a short distance to the nearest store or restaurant for lunch or a snack refill!

This urban field experience allowed me to experience firsthand how easily people can dismiss what is in their own back yards and surroundings.  But those places are filled with habitats supporting a diverse range of plants, birds and animals, if you just look.  And I don’t mean just in the wonderful designated park areas that are home to many species of urban wildlife; rather, I’m talking about the ditches and culverts along roadsides, and the shrubby areas at the edges of vacant lots. This fieldwork also revealed to me how the creatures living in these places are affected living side by side with humans. I saw how beneficial urban ponds were – how they collect run-off from roads and in turn become mini ecosystems that effectively lower bacteria n the water and water temperature, allowing the pond to become habitat for many species. I have also experienced how plants like cattails can remove contaminants from the water so that they are not released into the greater environment and witnessed the destruction that can occur if silt barriers are improperly installed around constructions sites.  These barriers limit the escape of dirt and silt; if they aren’t installed properly, it can result in water courses being choked out by the resulting silt.

It is easy to disregard or even be blind to places that could be wildlife habitat in an urban environment. What you might think is just a culvert could be a biodiverse diverted stream. By retaining water in the urban environment, this stream can aid in reducing the potential for flooding while forming a connection between habitats. Keeping these places intact and part of the urban landscape is essential for both the human and non-human residents of our cities.

Melanie is a PhD graduate of the Department of Biological and Environmental Science at the University of Stirling (UK), where she researched the climatic and environmental changes occurring on the Northern Isles (Shetland and Orkney) from the end of the last glaciation through the early Holocene (16,000 – 3,000 years ago) using diatoms, pollen and geochemistry. Her MSc work explored the relationship between diatom species communities and water-depth gradients in lakes across northwestern Ontario. She has always had a love of water and is interested in limnology/aquatic ecology and paleolimnology and how they can be used together to answer questions at many spatial and temporal scales.

Seeing the forest AND the trees

Within half an hour of starting my new job, I knew I was in trouble.

I was sitting in the passenger seat of a truck driven by my new boss, travelling down an Alberta highway at 110 kilometers per hour.  Every few minutes, without taking his eyes off the road, he would randomly (at least, so it appeared to me) toss out the name of another bird species.

“Hooded merganser.”

“Blue-winged teal.”

“Black tern.”

Most of these species were only names to me.  Given a good bird book, a pair of binoculars, and at least a full minute with a clear view of the bird, I would probably be able to ID them.  But IDing them based on a silhouette glimpsed for a second out the window of a moving truck…it didn’t take me long to conclude that my boss had to be superhuman.  And also that my tenure at this job might be a great deal shorter than I had originally hoped.

 

Having (finally) finished my PhD this past winter, I’m now in the painful stage of figuring out what exactly I want to do with it.  So when I was offered a job as a field tech for a wildlife consulting company in Calgary, I jumped at the chance.  I figured that a decade of doing fieldwork for various degrees would equip me well for the job.  Shows how much I know….

As a grad student, I spent all my time in the field completely focused on my study species (whatever that happened to be at the time).  I’ve put in endless hours catching and banding individual birds, recording their behaviour, and monitoring their reproductive success.  For me, fieldwork has always been narrow in scope, focused on learning every single detail about one very small part of the ecosystem.

Working as a consultant is pretty much the exact opposite: the focus is broad.  No one is interested in the details of each individual bird; what clients want is the big picture.  So instead of spending all my time identifying colour banded individuals, instead I’ve been frantically trying to learn to identify dozens of species by both sight and sound.  (Given that more than 750 bird species breed in North America, you can imagine that the learning curve is pretty steep.)

And the broad focus of consulting extends beyond simply identifying species.  In fact, perhaps the best example of the differences between grad school and consulting is an activity common to both: nest searching.

Grad students studying birds frequently have to find nests in order to measure individuals’ reproductive success.  They need to know who an individual mates with, how many eggs it has, when those eggs hatch, how often (and what) the parents feed the nestlings, and how many of the babies survive and make it out of the nest.

Nest searching is also a common activity for consultants, but with an entirely different focus.  Under the Migratory Bird Convention Act, companies undertaking construction activities during the breeding season are required by law to take steps to avoid disturbing bird nests.  To do so, they hire consultants to map out the location of those nests, so they can be avoided during construction.

But finding a nest – particularly a grassland bird nest – can often take hours and hours of careful observation, lying in the grass and waiting for the birds to get so accustomed to your presence that they’ll bring food to the nestlings even though you’re close enough to see where they land.  Often you’ll be sure that you have the nest pinpointed – but when you leap to your feet and peer into the suspect patch of grass, you’ll find nothing, and have to start from the beginning again.  It can be an incredibly frustrating process, but it’s accepted as par for the course when you’re a grad student.  And the feeling of satisfaction you get when you finally part the grasses and see the gaping mouths of baby birds begging for food makes it all worth it.

The problem is, in the real world, it’s usually not possible to spend a whole day finding one nest.  As a consultant, you have a given area to search, and a hard deadline: at some point, construction will start, and you need to know where the nests are before then.  So instead of pinpointing nest locations, you’re on the lookout for any sign of breeding in the birds you see – then you watch them for just as long as it takes to approximate the general location of the nest.

When I first started doing nest sweeps as a consultant, I found this incredibly frustrating.  After many years of grad school, I’m used to taking my time, and discovering as much as possible about the birds (and nests) I encounter.  Having to approximate nest location (not to mention the stage of the nest) and then move on immediately to the next one drove me nuts.

But the more I do this job, the more I realize that it’s a trade-off.  I may not know every single detail about the birds I observe, but I’m also learning to recognize many species that I’ve never paid much attention to before.  I can’t tell you exactly where each nest is or how many eggs it has, but I can make an educated guess about how many species are nesting in a given area.  In fact, the more time I spend as a consultant, the more I like it.  The work is challenging, but it’s making me a better birder and a better naturalist.

I can’t deny that I do still miss the detail-oriented focus of graduate fieldwork.  But every once in a while, when it becomes necessary to know exactly where a nest is, I get to use those skills.  And when I do, the moment of discovery is just as satisfying as ever.
