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: doi.org/10.1038/s41467-021-2…

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. ai.googleblog.com/2022/01/se… #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: calacademy.org/events/scienc… @calacademy @GGAudubon

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 💜
Canadian-born Alice Eastwood succeeded Kate Brandagee as procurator and Head of the Department of Botany @CalAcademy. She rebuilt the herbarium from the 1500 type specimens she saved from burning in the 1906 earthquake to nearly a third of a million, and described 395 species.

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. @GSCGalapagos @SFStateBIO @calacademy @USFQ_COCIBA @jocotoco_org

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….
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! scmp.com/lifestyle/travel-le… Nice work @canopymeg @calacademy

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... authors.elsevier.com/c/1d-PP… #ornithology

Gotta love poisonous birds! Nice article by Eldon Greij @BirdWatchDaily about toxic pitohui birds of New Guinea! birdwatchingdaily.com/news/s…

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

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. bit.ly/37mau5Z #MolecularPhysiology

If you're a birder, here is a rare opportunity to birdwatch Tom's Point in Tomales Bay: goldengateaudubon.org/blog-p… It is a great time of year, and you're supporting @GGAudubon

Much of conservation depends upon our perceptions and emotions. Colleagues who study owls are conducting a survey to understand how people think and feel about owls! Please take a minute to fill out their questionnaire... you-and-the-owls.webnode.com… @RoulinRoulin

Excited to be using PacBio HiFi technology to get a reference genome for the Galapagos Vermilion Flycatchers - and unlock the DNA in our 100 year old specimens... #HiFiExhibit @calacademy @DarwinFound

Super excited about this work coming out! Something that we've dreamed about and worked on for years. Excellent team, and thanks to @megan_kobiela for helping kick this off!
New work from our lab. Terrific collaboration with @alaurenoconnell, @CASbirdman, and @du_bois_lab on how poison birds and poison frogs avoid autointoxication. Context matters. Proposed toxin resistance mutations have no effects on the poison frog NaVs. biorxiv.org/content/10.1101/…
