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 … 🦉🧪

Virginia's warbler (Leiothlypis virginiae) from this morning, just for fun! 🦉🧪

First day in Arizona, first bird is a beauty (and a lifer!): the red-faced warbler (Cardellina rubrifrons). With @kevinfpbennett.bsky.social 🦉🧪

Double the trouble with these two blackburnian warblers (Setophaga fusca) from this morning! 🦉🧪

Congrats to Dr. Steph Szarmach for an amazing defense today!! Awesome work!!

Congrats to Dr. Dave Lutgen at U Bern for a damn fine dissertation defense today! Keep an eye out for some quality wheatear genomics in the near future, avec Reto Burri and Katie Peichel et al.

Nothing pairs better with red wine and lamb than getting tenure. Thanks @psubiodept.bsky.social (and all the colleagues, mentors and mentees along the way)!

It’s the most wonderful time of the year! 😍

and the Moose River Plains in all its glory. Five years, hundreds of warblers, early mornings, and a lot of great memories. @eliotmiller.bsky.social, I suppose we should probably head back for round II?

Now just some fun photos. First up, the aforementioned blood. Someone was NOT prepared for the black flies in the Adirondacks in early June ☹️
