    Why not a Booted Eagle? It looks rather small for the Ayres HE.

    New unified list of birds - Avilist

    And birds do have a great sense of smell (at least some, like tubenoses and kiwis). There is so much we don't know.

    New unified list of birds - Avilist

    Here you touch an essential point to me. Are we defining species for our lists? Or for science, to understand and be able to properly protect nature. I'm for the last, even if it means cryptic species. And that might mean not being able to be certain what species you've seen (european vs...

    New unified list of birds - Avilist

    This is a bad thing. Most duck species can interbreed and produce fertile offspring (I remember some research that Stellers Eider is probably a result of interbreeding between long-tailed ducks and an ancestor of the Eiders). We would probably end up with only one Aythia species.

    New unified list of birds - Avilist

    The problem with many of the morphologic differentiation is that is focuses on differences that humans can observe. And quite often this is not how nature works. Where is smell, infrared colouration and much more? Taxonomy has taken some steps, but still is quite close to how it worked in the...

    New unified list of birds - Avilist

    Taxonomy and species is a very human concept. What a species is exactly, is viewed differently per field of study and scientist. Also, since is is virtually impossible to test the BSC on all species and (at the moment) also for PSC, bird taxonomy will be guesstimates for quite a while. As an...

    California- Sutter county- Apr. 21; Strange bird seen and heard.

    Starlings are excellent imitators. They confuse me so often. So do expect sound you never heard from them.

    Help identifying this bird

    I thought so for a moment, too. But I think it is lighting. The shape of the bird is clearly a Raven.

    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    Or Trump might enforce them to lump all rare species so no further protection is needed.

    Help identifying this bird

    With this shape of the tail and the very obvious fingers, I would say Raven.

    Algarve Swift June 2024

    Interesting and neat picture for such a fast bird. Definitely not a usual Common swift. No clue if it is an aberrant Common swift or another species (with plain most likely, but an extreme vagrant should not be excluded).
