Thanks a lot! This one was born in captivity and is a falconry bird, so he has to look good I've never seen an US Buzzard, so I can't compare. Catching him in flight was not that difficult since he's on flight display in the park I work at, so I know the birds. He's quite a quick flyer, though.
Ah, thanks for explaining! Turkey Vultures! We currently have four of them on flight display (and four more to come...). Compared to Common Buzzards they really have ugly heads, but then again, so do nearly all vultures.
