Pumped to share our work on bird behavior and the 2024 Eclipse, in today's @science.org. 100k bird vocalizations + 10k continent-wide observations from the public = really fun collab led by Liz Aguilar, with @juncowren.bsky.social @mathcancer.bsky.social @imillercrews.bsky.social #NSF

And that's how you integrate digital elements into an exhibition. Part of the temporary "China's Dinosaur World" at the Shanghai Natural History Museum, China. Closing this November.

Coloured pencil drawing of a raccoon resting in the crook of a tree.

Finished! “Tree Fort”. Coloured pencil on cotton paper. With thanks to the raccoon who sat so nicely for me 🙏

I'm SOOOO EXCITED for this Sex(es) Across Origins Symposium at #SICB2026!!!! I just submitted an abstract for the complementary session (on bird plumage and social selection with @gamaevo.bsky.social), and I hope you consider applying, too! @sicb.bsky.social @sicbjournals.bsky.social

Illustration of a kelp forest in a teal ocean, rays of golden sunlight streaming in from above. Fish are swimming about, and near the bottom of a prominent kelp strand, a partially obscured leopard shark leisurely patrols the underwater forest. The palette predominantly features warmer teals, red violet, and gold.

A California sea lion rendered in rich brown and orange tones rests upon a rock in teal shore waters below a softly glowing orange sky. Its slender head is raised to look over its back and to the right while a large crest of white sea foam frames its figure.

Rendered in a rough painterly style, a shortfin mako shark leaps from a calm ocean tail over head, sea foam trailing its body in a loose arc. The shark, looking nearly metallic, is rimmed with orange light as a pale yellow sun hangs in a hazy orange sky, framing its streamlined figure.

A caribou stands low in a field awash in autumnal oranges and yellows. Its head raised slightly, it looks off to the side while a pair of tall, sweeping antlers rises from its head, a bright red crown of newly hardened branches. Velvet still clings to the antlers in patches and tatters.

Today is my birthday! I’d love if you could share my art or donate to a nature conservancy of your choice. 💚

Cuspirostrisornis, an Enantiornithine bird from cretaceous China, sits perched on a branch in the sunlight amid ginkgo and araucaria pines. It has a small yellow snout, black mask, orange back, white belly, and two long iridescent blue tail feathers. It has a fleshy snout rather than a hard beak, and two little claws emerge at the bend of the wing.

A green tortoise beetle climbs downward on a bug-bitten leaf. The beetle has transparent elytra that look like a clear glassy shield over its metallic green and black body.

Illustration of an island set in a shallow tropical lagoon, fringed by Casuarina and coconut trees. The rocky island is covered in vegetation and tiny dots - lots and lots of birds! More birds are seen flying toward the island, and in the foreground some of these are identifiable as Brown Noddy and Red-tailed Tropicbird. For Nature (NorthStar Games). Based on Bird Island, Saipan.

Illustration of an Indochinese Green-Magpie with its wings spread as it lands in a thicket of tropical foliage and flowers, all under a bright blue sky with a few soft clouds. This bird is brilliantly colored with a bright green crested head, black mask, red-orange wings, and fanned yellow tail with a black bar. For NorthStar Games' board game Nature.

Good morning #PortfolioDay! I'm Lauren, a biologist and scientific illustrator. I make art for publications, #SciComm, #BoardGames and more! Mostly birds, but bugs and plants and more! See my latest in the game Nature by @northstargames.bsky.social 🎨🪶🧪 #SciArt

Scratchboard illustration of seven American Flamingos.

Watercolor painting of a Spectacled Owl. He's dark brown on top and cream below, with bright yellow eyes and a white X on his face.

Portrait of a female Great Hornbill, a large bird, down to the upper chest. Her beak is huge, with a yellow-to-orange maxilla and damaged casque and a pale blue-grey mandible. She has a black mask covering her face and the base of her bill. Her eye is silvery and has nice lashes. Her neck shades from yellow through raw sienna to a pale burnt sienna, and her body feathers and the top of her wing are black.

Photo of a cute little Crimson-bellied Conure looking content. He has a grey breast and nape, green cheeks and wings, blue cap and flanks, bright red vest, and black beak. His eyes are large and dark.

So thrilled to have captured this image of iridescence on the wings of these 2 Swallows. It's tricky enough photographing these birds in flight but positioning yourself in relation to the sun a certain way can produce stunning results...

Macroevolution of body extremities reveals an integrated phenotypic response of coloration and morphology to temperature in a large clade of Neotropical passerines (Furnariida) ABSTRACT. Endotherms show smaller extremities (Allen’s rule) and larger body sizes (Bergmann’s rule) in colder climates, thereby reducing heat loss. Colora

I'm a little late to post about this, but I'm happy to see this paper out!

We found in ovenbirds that the color and size of their beaks, the color of their legs, plumage color and body size evolve together in relation to environmental temperature:

Extinction of experience among ecologists Fieldwork-based research and education in ecology are under multiple threats and are progressively declining. We call for greater attention to this ongoing loss of direct field experience within the ecology community, as it could have widespread consequences for science and education, ultimately hindering efforts to address the ongoing biodiversity crisis.

Where are all the field studies?

This ⬇️ important but rather depressing paper describes how conducting, & crucially initiating, field studies is becoming harder & rarer.

A short 🧵 (and a call for more fieldwork)

Our review is out in Nature Reviews Genetics! rdcu.be/d5AY2

We show how phylogeny-based methods can resolve the problem of non-independence in genomic datasets.

These methods must be considered an essential part of the comparative genomics toolkit.

Why aren't we talking about the real reason male college enrollment is dropping? We would rather talk about literally everything else.

So many good points in here.

When women begin to enter fields, first people cheer the pioneers. Then women do it more...and men get nervous.

And then men run.

And then they declare they NEVER wanted to do it anyway. Education is for GIRLS. celestemdavis.substack.com/p/why-boys-d...
