Graphic with the following text followed by The Institute for Bird Populations logo: Emergency Appeal: Federal Funding Cut Last week 9 of our federal grants were abruptly cancelled without cause. If you can make a donation today, it will have a big impact. Thank you for your support, The Institute for Bird Populations

🪶 If you are able, you donate here: birdpop.org/pages/do...
We lost roughly $1 million in funding without warning. Projects cancelled included all of our bird monitoring work for the National Park Service & projects w/ the Bureau of Land Management on Gunnison's Sage-Grouse, Pinyon Jays & more. 1/4

Excited to see this effort to bridge R and Word get a second chance! Reproducible writing, especially with coauthors that aren't code savvy is challenging. Btw, my vote is for redocx, 😁

Truly impressive number of birds migrating tonight. More than 800 MILLION birds up in the air right now❗ #BirdMigration

Quick - apply for this job as manager of our #Biodiversity lab at the NC Museum of Natural Sciences and NCSU to work with #tech and #biodiversity including camera traps, #AI and student mentoring Deadline is 9/23/2025 www.governmentjobs.com/careers/%7B0...

257. The Commission recommends that all Member States: (a) Employ all means reasonably available to them to prevent the commission of genocide in the Gaza Strip; (b) Cease the transfer of arms and other equipment or items, including jet fuel, to the State of Israel or third States where there is reason to suspect their use in military operations that have involved or could involve the commission of genocide; (c) Ensure individuals and corporations in their territories and within their jurisdiction are not involved in the commission of genocide, aiding and assisting the commission of genocide or incitement to commit genocide and investigate and prosecute those who may be implicated in these crimes under international law; (d) Facilitate the investigations and domestic proceedings and take action (including imposing sanctions) against the State of Israel and against individuals or corporations that are involved in or facilitating the commission of genocide or incitement to commit genocide; (e) Cooperate with the investigation of the Office of the Prosecutor of the International Criminal Court. 258. The Commission recommends that the Prosecutor of the International Criminal Court: (a) Examine, within its continuing investigation in the Situation in the State of Palestine, the crime of genocide for amendment to existing arrest warrants and addition to future application for arrest warrants; (b) Examine the involvement of officials mentioned in this report for inclusion as those most responsible for international crimes committed in the occupied Palestinian territory.

Today, the UN officially designated Israel’s assault on Gaza as a genocide.

As a party to the Genocide Convention, the U.S. has a legal obligation to obey our own laws, stop weapons sales to Israel, and demand a permanent ceasefire.

End the genocide. Ceasefire now.

Here's an example of some work done wtih @clear-lab.bsky.social on using colonial collections for Indigenous-lead science.

Figure 1A from the paper shows the distribution of black-headed (western) and rose-breasted grosbeaks (eastern) throughout North America. Small illustrations of males of each species are shown. Black-headed has a rusty orange breast and black head, while rose-breasted has a small reddish bib with a bright white belly. There is an inset map of South Dakota showing the transect across the hybrid zone

The first Aguillon Lab paper is officially out in early view at Evolution!! Led by postdoc @devonderaad.bsky.social, we’ve explored the hybrid zone between black-headed and rose-breasted grosbeaks in the Great Plains. #ornithology #hybridization #speciation #evolution doi.org/10.1093/evol...

Migratory birds aren’t equally efficient at all speeds. A new Lund University study shows thrush nightingales fly most efficiently at 7–8 m/s – the speed they actually use on migration.

Graphical abstract for a manuscript titled "Too few, too many, or just right? Optimizing sample sizes for population-level inferences in animal tracking projects". The workflow has been fully implemented in the movedesign Shiny application and R package, allowing users to easily test sampling strategies and assess the reliability of space-use and movement metrics, ultimately promoting more rigorous and impactful wildlife research and conservation.

This workflow has been fully implemented into the latest version of the #movedesign R Shiny app, making it easy for researchers to test and optimize their animal tracking sampling strategies! The package is now available on CRAN #rstats github.com/ecoisilva/movedesign

Graphical abstract for a manuscript titled "Too few, too many, or just right? Optimizing sample sizes for population-level inferences in animal tracking projects". The workflow presented in this manuscript evaluates sampling design by assessing sampling duration, sampling interval, and the number of sampled individuals needed to obtain reliable population-level estimates.

✨ New preprint! "Too few, too many, or just right?" 🌍🌎🌏 We explore how to evaluate study design in animal tracking studies by assessing sampling duration, interval, and, now, the number of individuals needed for reliable population-level estimates. #movementecology www.biorxiv.org/content/10.1...

Comparison of Bayesian Models to Estimate Survival From Dead‐Recovery Alone and Together With Live‐Encounter Data: Challenges and Opportunities Different models in the Bayesian framework for analyzing dead-recovery data, either alone or together with live-encounter data to estimate survival, are presented and compared. Although all but one o...

To estimate survival, a key parameter in population dynamics, ecologists use different statistical models to account for imperfect detection of living and dead individuals. M. Schaub and @jaumebadiaboher.bsky.social studied the performance of these models. Read more here: doi.org/10.1002/ece3...

The deadly risk of trying to reach food in Gaza An NPR journalist in Gaza describes his experience seeking food from a site run by private American contractors, facing Israeli military fire, crowds fighting for rations, and masked thieves.

. @npr.org is one of the only US national news organizations that still has a reporter inside Gaza, Anas Baba, and he keeps reporting even though he himself is starving. This piece is unbelievably powerful.

In our new paper led by Ursula Heize, we show that >90% of #WhiteStork nests have anthropogenic materials (plastics, paper, etc). Ropes are particularly dangerous: ~12% of the chicks became entangled on ropes, particularly on baler twine!
