Our new paper is in today's issue of Ornithology: "Effects of age, breeding strategy, population density, and number of neighbors on territory size and shape in Savannah Sparrow". Led by undergrad Sarika Sharma and our collaborative team. Read it here:

Last weekend I had the pleasure to deliver the guest lecture at the annual fundraising dinner of the Bruce Peninsula Bird Observatory. What a dedicated group of naturalists, conservationists, and bird enthusiasts! Thank you for inviting me. [📷 T. Havelka]

Yesterday morning, I noticed my students were wearing unusually nice shirts. It wasn’t until our lab meeting that I realized what was going on. It was a Hallowe'en send up; they were wearing the sort of shirts favoured by their supervisor. Hilarious! Happy Halloween, team. 🎃🐦‍⬛👕

This Hallowe'en I taught my Ecology class dressed as the symbiotic relationship between Bullhorn Acacias and Acacia Ants. Happy Hallowe'en! 🎃

I've enjoyed an inspiring visit to @michiganstateu these last two days, talking about vocal learning in sparrows, and sharing ideas about biology and ornithology. Thank you @mcgrawlabmsu and your great department!

“Every window makes a difference, if it’s a window that kills a bird.” A reporter from @TheWindsorStar found a window-killed migratory bird. He reached out to chat about window kills. Check it out:.

I feel honoured that our peacock photo was chosen as a finalist in @NSERC_CRSNG's "Science Exposed" photo contest. If you wish, you can vote for the photo to be considered for the "People's Choice" award. Voting closes Sept 22. Vote here: 🦚5/5

One morning while recording in the Bois de Boulogne, a pair of peacocks flew up into a plane tree. They howled their piercing songs, adding their high-pitched voices to our recordings of the city soundscape. 🦚4/5

Every morning we collected recordings of birds in different parts of Paris. Our recordings reveal that bird diversity is highest in areas with low urban noise. Also, our data demonstrate that urban noise drives birds to sing at higher frequencies. 🦚3/5

Last spring @Steph_Doucet and I conducted bioacoustic studies of birds in Paris. Paris is one of the world's most proactive cities when it comes to protecting urban parks and reducing human-generated noise. 🦚2/5
