There are a few exceptions to the MBTA. For example, it is legal to own a turkey vulture if you have a permit from the USFWS. Additionally, some states have their own laws regarding turkey vultures. For example, in California, it is legal to own a turkey vulture if you have a permit from the California Department of Fish and Wildlife (CDFW).
If you are interested in owning a turkey vulture, you should contact the USFWS or the appropriate state agency to inquire about the requirements for obtaining a permit.
