@adriftlab.bsky.social has never had government funding. What we have had - for nearly two decades - is a small group of deeply committed people, long-term datasets, and a community who makes it possible.
Our website now celebrates that out loud. 🔗 adriftlab.org
A diagram showing the evolutionary relationships among modern birds. The branches are color coded by the estimated likelihood of retaining ancestral character variability, with higher likelihoods in red.
A new paper I'm on is out today! Led by Stanley Somogyi, we suggest that ancestrally variable characters stabilized independently in different bird lineages, causing distantly related groups to retain similar traits and creating headaches for bird systematists. www.cell.com/current-biol... 🪶🧪
Os overwintering não são os indivíduos que não retornam na primavera e ficam mais um ciclo inteiro nas áreas de invernagem? Assim que eu aprendi na época dos grupos de emails do início do século
Hate my mapa astral!
As our university is undergoing restructuring, its partnership with the natural history museum where I work, the Academy of Natural Sciences, is in jeopardy. If you value the involvement of science museums in the community, please consider checking out this petition. c.org/Db5WKdZSQ8
The Academy of Natural Sciences was founded in 1812 — over 200 years ago — and it's been underfunded ever since. At a time like this when NSF budgets are being slashed and the museum is receiving little institutional support from Drexel, we deeply appreciate you spreading the word: c.org/Rkpyfx9HRN
Funny fact: most people ignore that every photo/video of an ET with 4 members, 2 eyes etc. is a proof in itself that it is fake. We have four 3-part limbs etc. because we are tetrapods. Believing in such ETs means Tiktaalik & allies could travel to other planets ~400 mya!
We need to correct (and further improve) the maps for two sister South American thrushes: Hauxwell’s and Cocoa.
Dear bird recordists: please pay attention to calls, too - they allow species recognition way better than songs in this case (and in thrushes and maybe Oscines in general?)

A map of northern South America with a revised range for both species. Legeng says: Accepted geographic distribution of Turdus hauxwelli (purple) and Turdus fumigatus (green). Circles represent diagnostic recordings identified in this study. Purple and green squares indicate examined specimens, tentatively identified based on vocal patterns and, in some cases, plumage. Yellow squares denote examined specimens whose identity remains uncertain until further data clarify their classification.
But there are some gaps left: their song is very similar, so we need their calls to tell them apart. But we could find no recordings of calls from Colombia, western Venezuela and parts of Brazilian Amazon where the two species must come into contact. We hope our fellows will now record them there!
Photo showing study skins thrushes in ventral and lateral positions showing the virtually identical plumage pattern between Hauxwell’s and Cocoa Thrush. Legend says: Plumage color variation in the Turdus fumigatus-hauxwelli complex. Specimens of T. hauxwelli (purple bar), from left to right: UFMT 5619, 5620 (from Rondônia), and 4157, 4820, 4883 (Mato Grosso). Specimen of T. fumigatus (green bar), UFMT 2660 (Pará). The asterisk denotes specimens voice recorded prior to collec- tion.
All fumigatus-like birds in Mato Grosso and neighbor states are actually paler/redder T. hauxwelli. We superficially speculate on the reasons for a polymorphic hauxwelli (from Gloger’s rule to mimicry of T. sanchezorum).
🚨New paper alert🚨
Proud to share the first paper by my student Nathália Victória.
We show that plumage pattern of Turdus hauxwelli and T. fumigatus converge in central Amazonia, but that is not intergradation. Voice allows clear segregation between the 2 spp.

Worked perfectly with my cell phone. Really nice (and wonderful recording).
👏👏👏
Bolsonaro jamais mandaria Bolsonaro cumprir pena em casa.
Bolsonaro chamaria os atendimentos médicos recebidos por Bolsonaro de regalia e desperdício de dinheiro público.
Bolsonaro debocharia com gosto de Bolsonaro.
I have a recording of a captive Alagoas Curassow. Should I upload it, despite being captive?
Por favor, não me alimente esperanças! 🥹
Check out the amazing lineup of workshops for #AFOWOS2026! Join us in Newport this summer to learn about bird tracking technologies for beginners, visualizing and analyzing bird movement data in R, and training sound into discovery with bioacoustics. #ornithology
This is a new/recent one. Thanks a lot. It will be very useful, too
Want a reliable way to tell the two cryptic giant hummingbird species apart while birding in the Andes? Use your ear! 🎶 In a new @fieldornith.bsky.social J. Field Ornithology paper, we show how their vocalizations differ clearly—making sound a slam dunk for identifying them in the field.

Pick your favorite flightless bird, use the power-ups wisely and avoid the obstacles. Enjoy!
This is all I could find so far:
Maybe our dear friends from UK can help?
@alexanderlees.bsky.social
@thelabandfield.bsky.social
I believe good UK libraries should have both journals. Thanks in advance!
Very interesting use of BirdNET. I believe such tools will be increasingly useful for taxonomy from now on. Nonetheless, to be fair, I must say Bret Whitney was the first to point out the distinct song of the new C. raucisona, almost 20 years ago! 🙂
Dear fellows from the outer worlds…
Anyone with access to the following works that could provide a copy/scan/pics?
Boles W. 1990 Glowing parrots—need for a study of hidden colours. Birds Int., 3, 76–79.
Boles W. 1991 Black light signature for birds. Aust. Nat. Hist., 23, 752.
Deeply grateful!
Te entendo. Por outro lado… nós ganhamos uma medalha olímpica num esporte na neve, né? 🤷♂️😁
Deu aquela dedadazinha marota por trás! “Toquezinho inocente”, achou que ninguém se importaria!

Do you still hold copyright of some sort? It would be great to either translate it to Portuguese or adapt it to Brazilian species.
Op, por que o nome tá aparecendo (erroneamente) sem hífen?
