Which two species' parts and feathers are distributed by the national repository to federally recognized tribes?

The correct answer is based on the legal protections afforded to certain species under federal laws, specifically the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. These acts recognize the cultural and spiritual significance of these birds to many federally recognized tribes, allowing for the legitimate distribution of their parts and feathers.

Bald and Golden Eagles are both protected under these laws, which means that their feathers and parts can be legally distributed to Native American tribes for traditional cultural uses. The national repository plays a crucial role in collecting and distributing these items to tribes that hold them in high regard for use in ceremonies, regalia, and other important cultural practices.

In contrast, while other species like the Grizzly Bear, Wolf, Whooping Crane, and California Condor are also protected under various conservation laws, they do not have the same provisions specifically allowing for the distribution of their parts to tribes in the same way that bald and golden eagles do. This distinction makes the Bald and Golden Eagles the correct answer in this context.
