under US law, it's illegal for anyone who's not a member of a recognised native tribe to own an eagle feather. the penalty is a $100,000 fine.
14 years ago when I had recently moved to Alaska, I went hiking with an Aleut friend, and she pointed to a feather lying on the ground and said "hey that's a bald eagle tail feather, you should grab it!" and I was like "uhh I'm very white and that's very illegal" and she went "they're fuckin everywhere up here man. I have 20." so she grabs it off the ground and hands it to me and says "there, now it's a ceremonial gift from an indigenous person."
and I'm like, okay, cool, I guess this is how we do things in Alaska. nice.
so I keep this bald eagle tail feather around for years. display it in my home among other cherished memorabilia from places I've lived and visited, etc.
on a whim, I have just now looked it up. there is no exemption to that law for a ceremonial gift from an indigenous person. the last 7 years I lived in the US, I was technically a bald eagle poacher.
probably a good thing I don't intend to move back there anytime soon. I wonder what the statute of limitations is on bird crimes.
