I mean, the title says it all: Genetic confirmation of an “uncommon mourningthroat” (Geothlypis philadelphia × G. trichas): A rare but persistent hybrid warbler. Fun stuff with @kevinfpbennett.bsky.social and Kurt Gielow, OA in @wilsonornithsoc.bsky.social!

Going to be a big month for warbler science! First out of the gates is @lannhiphung.bsky.social, with song & genomics of Nashville warblers. Eastern and western subspecies: non-overlapping and super distinct. Keep an eye on your life list 😉

Had the lab over last night. Tricked 'em—they made us dinner! Fresh pasta with smoked salmon 😋

The promotion and tenure celebration tradition at Penn State includes profs choosing an important book that has a deep, personal and professional meaning. I chose ‘The Beak of the Finch’ by Jonathan Weiner. Definitely check it out if you haven’t yet!

#AOS2025 don't miss @kevinfpbennett.bsky.social's talk at 11:15am on Wednesday in the Genomics 2 session (Ballroom C). We're cooking up some cool stuff with @mbtoomey.bsky.social on warbler carotenoid processing enzymes! 🦉🧪

Here’s an awkward red-faced warbler from this morning in New Mexico … to get eyeballs. The band on its leg was provided by the USGS Bird Banding Lab. It’s a thankless task, but they support permitting, band supply, data curation etc for TONS of researchers. They do such good, efficient work and … 🦉🧪
