Huge congratulations to my mentee, Miranda Margulis-Ohnuma, for winning the @sicb-dcb-dvm.bsky.social D. Dwight Davis Award for Division of Vertebrate Morphology best student talk at this year's @sicb.bsky.social meeting! So pleased to see her creativity recognized 🐍

bird people - what are some cool recent papers on migration?

(picking a paper for migration discussion in Ornithology class, I have some candidates but curious to broaden my options)

1/ Remember when Ted Cruz went to CancΓΊn as the Texas power grid failed? It wasn't just the people of TX left behind, it was also the wildlife. Out now @natecoevo.nature.com, our paper led by @mstager.bsky.social & @treeswallows.bsky.social documents how bad the storms were for birds.

Can a digital tablet cut back a country's overuse of antibiotics? Overprescribing antibiotics breeds antibiotic resistance. A new tool aims to lower a notably high rate of such prescriptions in Rwanda.

In parts of rural Rwanda, nearly three out of four pediatric health clinic visits end with an antibiotic prescription.

A new digital tool cut that down to just 25%, without compromising patient outcomes. Could it help slow the spread of antimicrobial resistance?

Oregon Senate Passes Bipartisan Measure Investing

in the State’s Natural Environment and Wildlife

House Bill 4134 relies on taxes paid by visitors in hotels, motels, and other vacation stays

 

SALEM, OR – The same gorgeous landscapes that draw tourists to our state will get new investments funded by those visitors under legislation passed today in the Oregon Senate. A tax on hotels, motels, and vacation stays will help pay for wildfire resilience, invasive-species eradication, wildlife conservation, and prevention of poaching. The broadly supported, bipartisan measure helps reverse decades of underfunding for protection of fish and wildlife.

INBOX: The Oregon Senate passed the 1.25 Percent for Wildlife bill, which will raise the state’s lodging tax by 1.25 percent to fund wildlife conservation programs, mostly through the Dept of Fish and Wildlife. This has been a long time in the making.

Excited to see this analysis based on AVONET & AVOTREX bird trait data.

Do bird radiations tend to avoid regions of trait space already occupied by other lineages? This analysis suggests the answer is yes!

The "Birds The Don't Exist" actually do exist, just in related passerine clades.

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Well this is fcking crazy. Work from @msbbirds.bsky.social and others found that Black Metaltail hummingbirds can drop their body temperature down to 3 °C (37 °F) during torpor. 🀯 Turns out birds aren't warm-blooded after all! royalsocietypublishing.org/rsbl/article...

Thrilled to share our new paper out in @science.org, led by FranΓ§ois Leroy and Petr Keil! Using the Breeding Bird Survey, we document not only a continent-wide decline in bird abundance since the 1980s β€” but, crucially, the acceleration of these declines over time. www.science.org/doi/10.1126/...
