Be careful about feathers. An endangered bird even if found dead, it's a big fine if you are caught with a feather! I picked up an eagle feather with the thought it was perfect to use to get dust out of my machine and DH about had a stroke. It's very illegal to have anything of an eagle!
...Native Americans are the only people allowed to posses an eagle feather and even they must have certification of tribal membership and the appropriate registration license to acquire one legally. And there is the rub... or a mere pale-face such as myself, possession of even one feather brings a fine of $100,000 and a jail sentence....
Many owls are protected too. I doubt a vulture is but you never know.
