Do you code? Want to help #Ornithology with an AI challenge for identifying birds by sound?
Checkout the BirdCLEF_2022 competition, put together by @CornellBirds, the Google Bioacoustics group, and others: https://t.co/GAPO7noNL6

WHAT flower blossoms in the cold of winter, is mostly blackish (and white)? And WHO thought to name it "Fetid adder's tongue"? Blooming in our front yard...

New paper out in @NatureComms! We show population differentiation in Wallacean & New Guinean birds is consistently & positively correlated with barrier strength and a species’ altitudinal floor: https://t.co/bGfFBqqMJ4

Amazing work by Google AI engineers creating automatic classifiers to identify birds in recordings. Significant improvements to the algorithms bring us closer to having functional tools for science. https://t.co/beijuIhmSP #ornithology @googleai @calacademy

Another rare beauty from Maldives #mesophotic ecosystems, Plectranthias winniensis. This one is very cryptic, and this is the first good picture I take of it in situ at about 105m depth. #hopeforreefs #perpetualplanet

Yes! We will be teaching our Master Birding Course in 2022! This is a great class for advanced birders who wish to really hone their birding and environmental leadership skills. For more information, click here: https://t.co/n6Bg72GDMm

Goodbye Galapagos! What an amazing research trip, working with @chavecito76, Ezra Mendales and Pooneh Kalhori on island birds. Thanks for the fantastic data, Galapagos! @calacademy @GSCGalapagos

Katharine Brandagee gave up her position for Alice Eastwood to come to @calacademy ! Happy to say this spirit of women supporting women is alive at CAS today 💜@RaynaCBell @alisonkestrel @flylogeny @rkim1853 @ArachnologyNerd @jacobs_sarahj @RebaFay 💜

[Jaime A. Chaves @chavecito76]

That’s a wrap! Galápagos field season completed. Happy students (sugar high), samples collected, and great memories made. A treat to share this time with @CASBirdman @PoonehKalhori Ezra Mendales.

Great hike to the highest point on Santa Cruz Island in the Galapagos. Plus a new life bird for me - Galapagos Rail, with @chavecito76 who studies them….

[Jaime A. Chaves @chavecito76]

Successful summit to the highest point on Sta Cruz-Island: Cerro Crocker. It has been a blast after 2 years of hiatus. Couldn’t be more grateful for having @CASBirdman as a colleague and two rockstar students @PoonehKalhori @Ezramenda114 #Galapagos @SFStateBIO @calacademy

Penang Hill was recently made a UNESCO Biosphere Reserve! It was soo cool working with everyone on that BioBlitz, and great to see the results!
https://t.co/kD2l60eoOS Nice work @canopymeg @calacademy

[Jack Dumbacher @CASBirdman]

Excellent work led by Devon DeRaad in Rob Moyle's lab at the University of Kansas sorting out the relationships of Chalophaps doves! Cool story of how birds diversified across these islands... https://t.co/zWNApeF2V8 #ornithology

Happy to see our new paper on the phylogeography of the 𝘊𝘩𝘢𝘭𝘤𝘰𝘱𝘩𝘢𝘱𝘴 doves out and fully formatted. This share link provides free access for 50 days: https://t.co/9o5MsmTKf4

[Jack Dumbacher @CASBirdman]

Gotta love poisonous birds! Nice article by Eldon Greij @BirdWatchDaily about toxic pitohui birds of New Guinea! https://t.co/Xj999zsMPU

[Jack Dumbacher @CASBirdman]

@AmphibiaWeb just highlighted our recent paper on toxin resistance and chose the Golden Poison Frog as Species of the Week! https://t.co/fYMdrPhoxq @calacademy

[Jack Dumbacher @CASBirdman]

The San Cristóbal Vermilion Flycatcher (Pyrocephalus dubius) hasn't been seen in many years and may be extinct. But with @DarwinFound biologists from Galápagos Islands, we are sequencing their genomes from 100+ year old specimens @calacademy! #HispanicHeritageMonth

[Jack Dumbacher @CASBirdman]

@calacademy @UCSF @Stanford Thanks @calacademy - So happy that this work is finally published!!!

[Journal of General Physiology @JGenPhysiol]

Evidence that toxin resistance in poison birds and frogs is not rooted in sodium channel mutations and may rely on "toxin sponge" proteins. A new study from Fayal Abderemane-Ali, @ElectrosomeUCSF, @megan_kobiela, @CASBirdman et al. https://t.co/Typ9JApONX

If you're a birder, here is a rare opportunity to birdwatch Tom's Point in Tomales Bay: https://t.co/l5P5xQ74RY It is a great time of year, and you're supporting @GGAudubon

[Jack Dumbacher @CASBirdman]

@GGAudubon is opening up classes again! Checkout Megan Jankowski's nest searching class: https://t.co/bDfJh9xrSZ. I birded with Megan this weekend and it was crazy how many nests we found...
