Golden eagle Aquila chrysaetos by Marcel Burkhardt

Combining high-resolution atmospheric analysis and global positioning system tracking data, @matthiastschumi.bsky.social and his team explored the role of gravity waves in soaring golden eagles, with results supporting the regular use of these waves. Read more here: doi.org/10.1098/rsif...

I found this in the forest next to my house today… any idea what on earth this could possibly be??? I am a biologist - but come on… this is sick!! I am sure these are 👾 that have arrived here without anyone noticing!!? 🤯

Pups in tow, Yellowstone-area wolves trek long distances to stay near prey - Berkeley News For the first time, a UC Berkeley-led research team has observed gray wolves outside of the Arctic migrating during pup-rearing season.

Excited to share the first publication from my PhD research about wolves using diverse movement tactics, including migrating and moving young pups, to track the partially migratory Cody elk herd in the Greater Yellowstone Ecosystem! news.berkeley.edu/2025/08/01/p...

Excited to share that we have just been awarded a NERC Pushing the Frontiers grant to work on between-group cooperation in the Shark Bay dolphins. We will soon advertise a 3 year post-doc to join the team - drop me an email if you might be interested! Pls share widely 🙏🏻

Really pleased to see Daisy Abraham’s first paper out. About something we know very little about: what happens when birds “divorce”. We had extensive discussion with one reviewer about whether this was the appropriate term to use. “Permanent breaking of pair bond” feels too much of a mouthful…

Using data of 49 radio-tracked White-back Woodpeckers, A. Ettwein, M. Lanz & G. Pasinelli provide the first estimates for seasonal and total home-range size of the species. For its conservation, at least 116-350 ha of forest should be present for one breeding pair. doi.org/10.1007/s103...

Congratulations @mdainese.bsky.social for getting your meta-analysis "A global synthesis reveals biodiversity-mediated benefits for crop production" cited over 1000 times!! 🎉 I guess this can now confidently be called a "seminal paper". And thanks again for making me part of it! 🙏

Thrilled to share our new article in @pnas.org highlighting global gaps in where we study animal movement—and outlining the next generation of smart bio-loggers.

Shifting Heights? A 40‐Year Resurvey of Alpine Marmot Distribution in Response to Climate Change The Alpine marmot (Marmota marmota) is an alpine specialist that might be particularly affected by ongoing warming. Based on historical occurrence data from the year 1982, we resurveyed the marmot oc...

Huge shout-out to Miriam Simma, who did all the recent marmot surveys and turned them into a fantastic master’s thesis! The original study can be found here: doi.org/10.1002/ece3...

A four panel comic titled Bird Sounds. In panel 1, labeled thrush, a wood thrush sings its beautiful eeohlay song against a forest background. In panel 2, labeled wren, a winter wren delicately sings tweedly tweedly tweedly. In panel 3, labeled warbler, a yellow warbler delicately sings sweet sweet. In panel 4, labeled heron in a death metal font, a heron screams KRAAGH against a background of fire.

Just got this draft cover for the 2nd edition of our book. It will be available soon!

Interesting story! The outcome will depend on the habitat of your neighbourhood! :-) But yeah, tape-luring can be potentially distracting and should thus used cautiously (and not excessively I mean)...

I am looking for a short video of multi (two or more) species of seabirds in a foraging interaction. The footage must be taken from above, ideally from a drone. The footage is for developing statistical techniques and would not be published. Can anyone help?
