Very proud of this collaboration with amazing colleagues from Ecuador, the Philippines and the US 🇪🇨🇵🇭🇺🇸. Island raptors should be a top conservation priority, as many are on the brink extinction meridian.allenpress.com/rapt/article... @mcclure.bsky.social @theperegrinefund.bsky.social

We teamed up with @hawkwatch and @hawk_mountain to rank the priority raptor species for conservation action in North American countries. Check out the results in Chapter 5 of State of the World's Raptors. science.peregrinefund.org/state-of-wor...

Species should be prioritized for conservation based on their evolutionary history and extinction risk. In Chapter 4 of State of the World's Raptors we outline our methods for ranking raptor species for conservation action. Check it out! science.peregrinefund.org/state-of-wor...

In Chapter 3 of State of the World's Raptors. We created Raptor Conservation Regions by grouping countries with similar raptor species. These regions can be used to study, monitor, and conserve the world's raptors. Big thanks to @mbzraptorfund for collaboration. Check it out! bit.ly/43IwFzQ

In Chapter 2 of State of the World's Raptors we examine the evolution of carnivory and its implications for being a raptor. Check it out! science.peregrinefund.org/state-of-wor...

In Chapter 1 of State of the World's Raptors, I review the importance of birds of prey, their plight, and the philosophy of the book. Check it out! science.peregrinefund.org/state-of-wor...

Please stop publishing in mdpi and frontiers journals.

The best thing you can do for the environment is donate to NGOs that take direct action and vote for candidates that actually care about conservation.

Single-blind #peerreview leads to more positive outcomes if you are: - male - White - in the US or North America - well-published or known in your field - affiliated with a prestigious institution Can we please make double-blind the gold standard now? 🧪 #academicsky #SciPub

New analysis confirms Snowy Owls are threatened with extinction. Great work led by Hawk Mountain Sanctuary with analysis conducted by @brols.bsky.social of @theperegrinefund.bsky.social. www.cambridge.org/core/journal...

Can anyone name some nonprofits who are directly working to prevent extinction?
