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.

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.

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.

Alannah Gallo is a biologist who works in environmental consulting in Calgary, Alberta. She has just started her Master of Science in Environment Management at Royal Roads University in Victoria, British Columbia.
