I'd appreciate some help identifying these three corvids I photographed in Austria during the Summer:

corvids

I know identifying corvids can be difficult, I'm not an ornithologist, just an amateur bird watcher. After looking through many images of various crow species and their hybrids, I've tentatively identified these as:

  1. Carrion crow (Corvus corone)
  2. Carrion crow × Hooded crow (Corvus corone × Corvus cornix)
  3. Carrion crow × Hooded crow (Corvus corone × Corvus cornix)
    I initially believed this to be a Hooded crow (Corvus cornix), but the broken coloration on the wings made me think it might actually be a hybrid as well.

Can someone here either confirm my identification or provide a more informed identification?

1 Answer 1

The first 2 are correct. The third one is actually a hooded crow. The different color of the wing depends on the generation of feathers. Feathers of different generations (changed during different time) are abraded (used) in a different way. The wing feathers of this guy are older than the rest.

Cheers and good luck birding :)

Thanks, can you show some images of hooded crows at different generations (or perhaps just their feathers) for comparison? –  p.s.w.g Sep 16 at 16:53
