Someone brought our admin a stunned young warbler in a cup this morning. Luckily we know just who to call! Thank you @jonathanjojochu.bsky.social & Jelany for your expertise, and shoutout to Sofia for catching the bird when it was flying around the office! 😅

Our lab had a fantastic time at the Soc. Cnd. Ornithologists meeting in Saskatoon last week! Thanks to @sco-soc-2025.bsky.social and the organizers.

And congrats to Jelany Duali for winning best student talk!

Here is an Op-Ed @qwebber.bsky.social and I wrote on the absurd Bill 5 being proposed by the Ontario government. It is amazing we have to say these things but word needs to get out for those in Ontario....and for those in the rest of Canada and the U.S: keep watch!
