Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

New burrowing owl behavior for me today-- taking a bath in the rain! So cool! 🪶

A mother and baby grebe are swimming in a pond. Two chicks are riding on the parent's back, while the other chick is rushing to get on the parent's back. カイツブリ親鳥と3羽のヒナ。 親鳥はヒナ2羽を背中に乗せ、1羽のヒナも背中に乗ろうと急いで泳ぎます。

I finally managed to draw a little grebe🪽

Fluffy white beanie baby owl with large eyes and tiny colorful wings, tucked in the crook of a small sapling so it is over a tray of peanuts.

Half a sheet of notebook paper taped to a tree trunk. In very small, almost unreadable handwriting it says "Please don't touch doing sciences" in blue ink. Definitely could be written larger on the sheet; I had to use binoculars to read it from the path.

When I saw a beanie baby owl in a shrub in the urban park behind my house I wondered if someone was trolling me, but then I saw the "Please don't touch, doing science" note an noticed the owl was above a tray of peanuts, with a predator-model-free (owl-less) tray nearby haha

Jane Goodall and the Legacy of Colonialism Transcript: Last week, English primatologist and anthropologist Jane Goodall died peacefully in her sleep at the age of 91, and so while sad, this news offers me a unique opportunity: to make a sec…

A small hummingbird with deep magenta and violet plumage is perched on a branch, fluffing its feathers. Its head is turned to the side, showing a bright white forehead and a long, slender bill, set against a soft green background.

Hey Folks! the fancy pigeon of @veppart.bsky.social has some unexpected veterinary costs so Valeria is extra enthusiastically welcoming art commissions!

New graphic for Doc's vet bills. Please consider buying art of anything at all! My little dude needs surgery asap. Feel free to share this graphic far and wide!

Very pleased to see our study that formally quantifies the society of zebra finches. They have different types of relationships, and these form tiers, but they do not form a multilevel society.

This was a very nice collaboration with great colleagues.

Earlier this year, Dr. Jane Goodall sat down for an interview for Brad Falchuk’s new Netflix series, Famous Last Words.

The premise of the series is to interview people on the condition that the interview not air until the subject has passed away.

#bowerbirds are the only birds that build structures used specifically for courtship. But why and how did this remarkable ability evolve?

We discuss some possibilities in our new review in Emu - Austral Ornithology!

A new paper I'm on is out today! Primarily the work of @evodevoba.bsky.social, we found that distinguishing skull features among chicken-like and duck-like birds do not always arise later than shared similarities during embryonic development. evodevojournal.biomedcentral.com/articles/10.... 🪶🧪

Hey, we all like fireflies, right? Of course we do! So please: LEAVE YOUR LEAVES! Firefly larvae need the protection that fallen leaves provide to complete their life cycle. Even just allowing part of your yard to be covered with leaves can help the arthropods/invertebrates/microfauna living there.

I visited the office for a work function (I work at home), and was happy to find these ruddy duck (aka best duck) items on display: a needle-felt ruddy on a coworker’s desk, and an 80-year-old watercolour by our first staff artist. #birds
