Enjoying a crafternoon at Fairweathers with my lab following the seminar with painting and clay!

I was honored to share our research, including #citizenscience projects for the general public in the yearly nature&citizensci event, ignited by Otso Ovaskainen et al. Great questions from the audience! www.jyu.fi/fi/tapahtuma... @uniofjyvaskyla.bsky.social

Searching for cool rocks and fossils!

Western Hudson Bay polar bears are in their usual spring hunting area. I'm in Churchill now waiting to start field research & deploy eartag satellite radios but no helicopter (stuck in Igloolik in a white out) & the weather here is snowy. Hoping for a helicopter & sun.

Join us in bringing the stream at Amaolo Nature Sanctuary into the 21st century! In the 1940s, the stream at Amaolo was straightened and its ecological functions were disrupted. Today, we have the chance to restore it. Donate today and be part of the restoration >> buff.ly/rUHNShc

Another amazing @mcmasteruniversity.bsky.social Biology Undergraduate Symposium is complete! Congrats to my Honours thesis students Nikki and Shriya for on your amazing thesis presentations as well as all of the undergrads for your hard work this year!

Easter fun 🐣🐇!

Just discussed this with another female junior PI... It's obvious but maybe more data helps. What is necessary, is that policies aimed at retaining parents in academia do not treat fathers and mothers equal. Early on, the impact is not equal and denying this ends up disproportionately hurting women.

Just 3 more days left to the #CanGeoPolarPlunge! Here’s an Arctic plunge I did in the Victoria Strait @cangeo.bsky.social ! While it won’t be as cold, I promise to make my plunge at Lac Meech just as exciting!!! #BeBoldGoCold #CanGeoPolarPlunge ❄️🥶 Please support at secure.qgiv.com/event/royalc...

Lots of Hudson Bay polar bears are towards the NW. Something good up there this year? Some bears are right along the shore lead - an area of open water & thin ice. There are more bearded seals & harbour seals in this area so possibly the attraction.

On March 8, 2026, I will be embracing the cold and joining the 2026 #CanGeoPolarPlunge at icy Lac Meech! Donations will go toward the programs of @cangeo.bsky.social and @rcgssgrc.bsky.social that support students, educators, explorers, & scientists! #BeBoldGoCold ❄️🥶 secure.qgiv.com/event/royalc...

Congrats Aiden! Way to read! 📚

Beautiful photo of the Choy lab together at Graduate Research Day @mcmasteruniversity.bsky.social! I’m lucky to work with such a bright and supportive tram of graduate students!

In addition to giving a poster or presentation, every member of my lab participated in the first ever Sci-Art competition at GRD! I’m lucky ro work with such a creative bunch! 🎨🖼️

Today was Graduate Research Day in the Biology Department @mcmasteruniversity.bsky.social! I’m really proud that every one of my graduate students participated in the event, sharing their research in a poster or oral presentation!

Great day for a skate on our outdoor rink!

Best Christmas present!

Inuit artifacts over 100 years old—included a hand-crafted, sealskin kayak—are unveiled to the public at the Canadian Museum of History. Hear more on APTN News Brief:

Happy to share that my team & I were successful in our application for a Planetary Health Seed Grant to support an Interdisciplinary Living Lab and Bird Observatory @mcmasteruniversity.bsky.social! Thank you Jay Robb for sharing the news in your wonderful story! science.mcmaster.ca/bird-observa...

My grad students did an amazing job on their presentations at the @mcmasteruniversity.bsky.social Graduate Research Symposium today! Extra kudos to my PhD student Tory for hand drawing (using a tablet) every one of your slides! They were beautiful!

Congratulations George Stroumboulopoulos on your RCGS fellowship! I grew up watching you and am truly honoured to be mentioned by you! www.linkedin.com/posts/stromb...

At Grimsboo! 👻🎃

Had an amazing time at the Canadian Ecotoxicity Workshop in sunny Victoria last week! What a beautiful venue for a conference! It was also great to reconnect with my PhD advisor Lisa Loseto & Kendall Island beluga field camp team member JP Desforges at the banquet!

Nice to see the Choy lab featured on the Haldimand Bird Observatory blog! www.haldimandbirdobservatory.com/september-25...

My lab and I from @mcmasteruniversity.bsky.social had the wonderful opportunity to visit the Haldimand Bird Observatory this morning! Thank you so much Rick Ludkin for sharing with us your knowledge of local songbirds and providing us with hands-on training and of course, the free humour!

Today, 165 2nd year undergraduates participated in the Great Canadian Bioblitz at McMaster Forest this morning! Most had never been to or even heard of McMaster Forest! Their enthusiasm was contagious with many species sightings! A special thanks to the leaders of Nature @ McMaster for hosting us!

Thank you Jay Robb for featuring my students and I in this wonderful story about our canoe lab trips to learn about the Cootes Paradise ecosystem for my Fundamental and Applied Ecology course at @mcmasteruniversity.bsky.social science.mcmaster.ca/paddling-in-...

Today, my @mcmasteruniversity.bsky.social BIOL 2F03 course started our first labs with a canoe trip through Cootes Paradise to learn about the ecosystem. We saw egrets, ospreys, & great blue herons! The students had a blast & for some it was their first time canoeing!

Here’s a video of @mcmasteruniversity.bsky.social grad students Abby & Flynn removing an adult rhinoceros auklet for a body mass measurement after a respirometry trial. All birds were handled with proper training and permits. Listen to their amazing experience here: www.cbc.ca/listen/live-...

This is one of my favourite themed episodes that we do, where we get to really lean into the stories of scientists as explorers and adventurers. Season 50 of Quirks & Quarks kicks off today! www.cbc.ca/radio/quirks...

Amazing interview by @mcmasteruniversity.bsky.social MSc. students Abby Eaton and Flynn O’Dacre with CBC Quirks and Quarks on their seabird research on Middleton Island, Alaska!! Stay tuned for the radio broadcast tomorrow at noon in all time zones on CBC Radio! www.cbc.ca/radio/quirks...

What’s it like to work from cliffs on an Arctic island with foxes, belugas, & polar bears (OH MY)! Read Jolie Nguyen’s experience studying thick-billed murres on Coats Island, Nunavut as part of her MSc. project @mcmasteruniversity.bsky.social ! science.mcmaster.ca/two-summers-...

Daycare graduation

just completed 3 x 5km run in 1 week! Bring on the new term! 🏃🏾‍♀️

Kite making + foam party = a perfect day!

Excited to play with ozobots at the library!

My little fish passed his swimming course!

Happy that these two get back today after a successful seabird field season on Middleton Island, Alaska! Here they are banding glaucous winged gull chicks! All birds were handled with proper permits and training.

Happy to advance another Middleton Island kittiwake project (rapid behavior changes associated with endogenous and exogenous corticosterone increases). This field site provides surreal access to these #seabirds - it's a dream for studying the physiology/behavior interface in free-living animals.

“York University scientist Sheila Colla remembered as a fierce advocate to save wild bees. Colla, 43, died Sunday of cancer. She successfully fought for the rusty-patched bumblebee to become the first bee listed as an endangered species in Canada and the U.S.” www.thestar.com/news/gta/she...

Last day in Antwerp!

I'm sure many I know here remember Sheila from our days on X. I'm so sad to read this news. Her advocacy influenced my thinking and was part of the inspiration for my pollinators' garden. What a loss to her family, community, bumblebees and science. #GiftLink 🎁 www.thestar.com/news/gta/she...
