Well done in the hydronym. On the other hand, he could have avoided to (mis)use “America” for US. We (true America) are way more relevant than a single country. And the lake is Ontario and the gulf is of Mexico, of course. Let’s adhere to the correct toponyms. 🙂

So we know AI helped a negligible number of students. But how many did it harm? I've crunched the raw data provided by the lead researcher, and what I've found is that ~9,500 students using AI studied less than even the *least* studious, non-AI using student. This should shock the conscience.

New paper in @bou.org.uk's Ibis: there is still no comprehensive database of bird type specimens. Many major collections have no published type catalogue at all. Where they exist, they're often print-only, partial, or decades out of date. 🧵

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?) #ornithology
054
Vitor Piacentini @piacentini.bsky.social · 24/03/2026
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!
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.

Vitor Piacentini @piacentini.bsky.social · 24/03/2026
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).
