Our new commentary rdcu.be/ftx6h in @natecoevo.nature.com written with folks from @inaturalist.bsky.social and @cornellbirds.bsky.social shows that use of AI to manipulate existing or create new wildlife images undermines the huge value of vast citizen science databases. 🌍🪰🪶 #Ornithology 🧵 1/10

Terrific example of the complex moult strategies common across many tern species. Adult birds with 3 generations of feathers in one feather tract from definitive basic, alternate and supplemental moults (eg in the Primary coverts)👌

Bsky ornithological hivemind -- recently in Panama doing Wood-Quail playback experienced repeated incidences (across species&individuals) of forest raptors responding to Wood-Quail song. A first for me - anyone reading this experienced similar things?? Would like to hear from you! #ornithology

These are the relevant morphometrics to measure on a flycatcher. Although absolute measurements are very helpful, relative metrics, essentially proportions, are just as useful. These are the features that can be measured from photos or what you see, with some training, in the field.

Acadian Flycatcher migratory routes rewritten. In spring, most of the migration takes a largely land-based western circum-Gulf path. In fall, they take an easterly route through Florida and across the western Caribbean, bypassing most of Texas. Most fall Acadians in Texas are misidentified.

Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶
Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.

Whenever I hear someone say that ebird data sucks and is unreliable, it tells me that they are repeating something they were told 15 years ago, and that they haven’t read any of the truly groundbreaking methods developments that have made ebird one of the best macroecological datasets on earth
