Hi Kate!
We are thinking almost certainly Golden Eagle. I checked against Great Horned Owl and Osprey, both a bit too gracile I think. I've attached some photos of the same bones of Golden Eagle with similar views to your photos so that you can see the comparison. Hope this helps!

Greetings from China,

These bird phalanges come from an assemblage dating to 4000 years ago in the Yellow River Valley region. I would greatly appreciate any help to identify them. This is my first time posting photos, so please let me know if the link does not work:


Many thanks!
