Pressure data also allowed us to calculate flight altitude throughout the yearβ€”and in a cool twist we found that the max altitude of our birds matched the altitude at which @catieivy.bsky.social found captive MYWA would maintain flight in a hypobaric wind tunnel!

Geolocation using atmospheric pressure is a really exciting new avenue for tracking small songbirds, and we found that using pressure allowed us to characterize the migrations of these birds at a much finer scale than using traditional light level methods.

While not many small songbirds have been tracked from this region, these MYWA followed a similar route to blackpoll warblers (minus the trans-Atlantic flight!). The routes of both these species may be retracing historical paths of range expansion from glacial refugia after the Last Glacial Maximum.

Stable isotopes in feathers collected from 167 MYWA breeding across northwestern North America showed that only a small proportion of birds in each pop. may migrate to the Pacific Coast. MYWA are often thought of as relatively short distance migrants, but not so in these high latitude populations!

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 Coastβ€”rather than to the closer Pacific Coast non-breeding area πŸͺΆπŸ§΅ link.springer.com/article/10.1...

A comic graphical abstract by illustrator Rush Dhillon showing two wood warblers and their spider prey. The graphs illustrate the read abundance of these spiders in the warbler's fecal samples.

I could give you a great summary of our new warbler diet paper… but if a picture says a thousand words, this awesome graphical abstract by @rushstudio.bsky.social tells the whole story. πŸ¦‰πŸ§ͺ

semi-regular reminder that ICE was only created in 2003

when you are asked to imagine a world without ICE, you're basically being asked to remember where you were when Lilo & Stitch came out

Science communication is more siloed than ever - platforms, algorithms, and lack of in-person contact can cost us opportunities to connect with one another about science. @sarahmackattack.bsky.social talks about how we, as scientists, can expand our audiences and connect with our communities.

The lack of mainstream coverage of regular huge protests reminds me of a talk from a Twitter employees who explained that they had to drop BLM off the Trending Tags section because otherwise it would have been there permanently. The modern media environment has no appetite for sustained movements.

Opinion | Don’t call it β€˜Alligator Alcatraz.’ Call it a concentration camp. This facility’s purpose fits the classic model, and its existence points to serious dangers ahead for the country.

"The Nazis... imagined their targets would self-deport. Once the myth of self-deportation collapsed, they turned to more punitive measures. On Tuesday, Noem similarly noted the Everglades camp was meant to frighten immigrants into self-deporting. 'If you don’t,' she said, 'you may end up here.'"
