Fun @nationalgeographic.bsky.social piece by Melissa Hobson on how #rightwhale mums turn upside-down to regulate their calf's nursing. From a paper by Renae van Noort, @katesprogis.bsky.social , Barbara Stewart & Fredrik Christiansen: @uwaoceans.bsky.social & @marinemammalsau.bsky.social 🐳🌍🦑🧪

Scientists finally have an explanation for this weird whale behavior
Mother right whales were captured in a rare video with their bellies up. It could be a sign they need a break.

If you’re a Master’s student interested in movement ecology, biologging, noise & conservation, join me and some great collaborators for an internship on how wind turbines and associated noise shape lesser kestrel (Falco naumanni) movement and behaviour.

New paper out! 🚨 We describe pre- & post-nursing behaviors in humpback whale mother–calf pairs from a unique dual-tag dataset: one tag on the mother, one on the calf. It’s a rare look underwater at interactions we can’t see from the surface. 🌊 onlinelibrary.wiley.com/doi/10.1111/...

Hot off the press 📣: one of the most surprising and unsettling findings of my PhD. A novel social tradition emerged in the tool-using white-faced capuchins of Jicarón island… abducting and carrying the infants of another species. Thread with gifs, videos, and all the bizarre details 👇

(1/7) 🐋 Remember those humpback calf-perspective videos I used to share? Super cool, but they only showed what the calf’s camera could catch. What if we could zoom out and see the whole scene?

Most diving mammals must work against their buoyancy until they reach a depth where they are neutrally buoyant, but not adult baleen whales. They use their laryngeal sac filled with air to adjust their buoyancy to remain suspended effortlessly at any depth journals.biologists.com/jeb/article/...
