It is perfectly legal to own and sell these feathers in the U.S. without a CITIES permit, including the Military Macaw. You do have to have documentation that the feathers came from domesticated birds (pets, zoo, or aviary birds) to be able to legally sell them.
To sell these feathers, you need not provide the buyer with a certificate of domesticity; however, you need to have the documentation that the feathers came from domesticated birds in your records to avoid problems.
As Fred posted, raptor feathers are highly illegal to posses unless you are a Native American who is a member of a federally recognized Indian Tribe. Possessin a single raptor feather can result in a fine of up to $10,000.00 and/or 10 years in federal prison as well. Defintely not worth the risk.
