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!

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!

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!

Off to Anchorage today to help my grad students with their seabird research! My students are very creative in the ways they use social media to engage the public with their favourite birds.

My @mcmasteruniversity.bsky.social students learned how to measure and collect fecal sacs from their first day-10 tree swallow chicks at Windermere Basin with some guidance from Environment and Climate Change Canada! We have 6 colonies across Hamilton that we are monitoring for priority pollutants!

First day of diet sampling of day 8 starling chicks was a success, as part of Julianna Colafranceschi’s PhD project @mcmasteruniversity.bsky.social! Prey were collected from 2 out of 2 nests today! And it was such a beautiful day to be out doing field work with these students! 🐦🐦⬛
