Walk Past that Eagle Feather?
Some of the people who sell items made with wild-animal parts know the law, and some do not, based on what I have seen at festivals and on websites.
So here is a reminder. Possession of raptor parts in the United States is federally regulated, and possession of eagle feathers or parts are highly regulated.
Basically, unless you are a registered member of an American Indian tribe, you can’t have it. And for them there are rules, summarized at the article linked above.
If you find that feather on the ground and you pick it up . . . just don’t say that you were not aware.
(Somehow this train of thought reminds me of one of my big sister’s favorite sayings: “Don’t forget to put a quarter in the parking meter before you go in to rob the bank.”)
