Out now in Movement Ecology: We used multi-sensor geolocators to track myrtle warblers breeding in Alaska and found that they migrated much farther than expected to the Gulf Coast—rather than to the closer Pacific Coast non-breeding area 🪶🧵 link.springer.com/article/10.1...
Left panel: A small black, grey, white and yellow songbird wearing a tracking backpack. Right panel: A map of North America showing a migration track beginning in Alaska, crossing east across the boreal forest of Canada, and then turning south to the coast of Texas before retracing the path north.

A bit late to post, but I defended my doctoral dissertation! It was an honor to have so many colleagues, friends, and family attending my talk and celebrating with me throughout the weekend. I'm looking forward to starting a postdoctoral research fellowship at the Smithsonian Migratory Bird Center!

Some good news for a Friday morning: it's been a long road, but this work from my M.S. is now published! Using RAD-seq data, we assessed genetic diversity and the demographic history of the world's second largest migratory wildebeest population in Zambia's Greater Liuwa Ecosystem

Excited to share our preprint on the migration of high-latitude breeding myrtle warblers! Using barometric geolocators and stable isotopes we found most birds migrated >5,000km to the Gulf Coast rather than to the closer Pacific Coast wintering area. biorxiv.org/cgi/content/...

Great to be back doing some field work this morning with some local warbler banding 🪶 (all birds handled with permits)
