🐦 Do some birds have #PrettyPrivilege?
💫 New paper: doi.org/10.1098/rspb.2024.2846
We show that ~half the variation in research effort on 293 bird species in US+Canada is explained by just 3 factors: 1)visual appeal, 2)range size, & 3)# of universities w/in ranges. What we did & why it matters:🧵

Remote‐Control Science in Ecology: A Hidden Face of Scientific Neocolonialism

We introduce the concept of “remote-control science” as a modern form of scientific neocolonialism in ecology, where researchers, preferably from the Global North, control projects in the Global Sout....

💥BREAKING: Birds in a tropical pluvial rainforest of the Chocó have been quietly changing in morphology for 109 years. Some have shrunk, others grown. Tails grew longer, bills grew deeper. Even in forests with continuous cover, climate change may be rewriting evolution in real time.

Migratory connectivity and potential nonbreeding sexual segregation in Gray Vireos (Vireo vicinior)

Nonbreeding distributions of most migratory North American breeding birds are relatively well-defined, but population- and sex-specific nonbreeding dispersion is poorly understood. Nonbreeding fact...

silas fischer @silasfischer.bsky.social · 18d

🗺️ Why does this matter? Nonbreeding factors can limit population growth and manifest differently among populations and sexes across the annual cycle. For conservation of migratory animals, we need info about these complex patterns—we need to be studying female birds and multiple populations! 4/

silas fischer @silasfischer.bsky.social · 18d

⛰️ We also found that breeding popn’s occurring closer together don't necessarily overwinter closer together. Birds breeding @ Sevilleta NWR (NM) wintered mostly along the MX Baja Peninsula, whereas birds breeding only ~90km N of there @ Kirtland AFB (by Albuquerque) seem to winter in Sonora MX.. 3/

A multi panel figure. First panel top left shows nonbreeding dispersion probability density functions of male and female vireos that bred at Sevilleta (blue). Panel to the right shows Utah birds’ dispersion (orange), and the last panel shows Kirkland birds (yellow). Males are marked with squares, females with circles

silas fischer @silasfischer.bsky.social · 18d

💫 Unexpectedly, we found ♀ appeared to winter ~5° farther N than ♂—suggesting sexual segregation on the nonbreeding grounds, which may be explained by larger body size in ♀....the OPPOSITE trend expected among songbirds exhibiting sexual segregation (where ♂ typically winter farther north). 2/

A two panel boxplot. The left panel shows female and male nonbreeding longitude, where the females and males largely overlap. However, the left panel shows latitude, depicting clear separation with females occurring almost 5 degrees farther north than males. Boxes are in green, and there is an illustration of a vireo with a geolocator.

🐦 Never got around to posting about our paper on Gray Vireo #migration in @wilsonornithsoc.bsky.social (1 of my MS chapters), but better late than never!

We used light-level geolocators to track migration ecology of ♀ and ♂ Gray Vireos from 3 breeding sites in New Mexico and Utah USA… 👇 short🧵 1/

Today 14 scientific societies in #ecology #evolution and #marineScience are publishing the results of a survey that finds negative impacts of federal policies on food security, flood mitigation, infectious disease preparedness, and wildlife conservation: 🧪👩‍🔬 www.firsthandaccounts.org/impacts/2025...

This infographic describes the main results from a survey of members of 14 scientific societies. There is a pie chart showing that both academic (58%) and non-academic (42%) responded to the survey. It lists statistics: 85% of respondents reported uncertainty about the future; 71% reported federal training programs were "very" or "extremely important"; 83% reported negative impacts or irreparable harm on their field of science. There is a word cloud summarizing open-ended responses with the largest words "student research fund federal grant". Eight major themes in the responses are listed: disruption of research with societal important; concerns of closure of the USGS Bird Banding Lab; Early Career Bottleneck; Restricted Freedoms including travel and speech; Decline in Government Efficiency and Expertise; Concerns about Biased/Removed Data and Data Gaps; Concerns about the Ability to Meet Legal Mandates; and From Positive Impact to Irreparable Harm. There are icons for each participating society and a QR code for website and data availability.

ad to come, but I'm looking for an M.S. student to study the conservation genomics of swift foxes on the American Prairie Reserve in Montana beginning 9/1. this is a collaboration w/ Smithsonian & Justine Becker; strong candidates will have prior genomics experience and be up for remote fieldwork
