Discussion re: birds of prey

[andreanar]

Another thread got me thinking about the laws concerning migratory and birds of prey. @Farmer Connie I didn't want to respond on the other thread, as we were off topic there as it is. LOL.
I understand the laws about these birds, but I just don't get the one about not being able to keep a feather if I found it on the ground. Not even the feather of a cardinal. I find all sorts of pretty feathers, and birds lose them naturally. Any thoughts?

I have a cardinal feather... uh oh

The law is there so people do not kill protected/native birds and use their feathers to decorate, etc. It's impossible to prove if a feather was found on the ground or killed for. Does seem a bit silly, though.
