Are turkey vultures endangered

Probably yes!

But it's not related to the name of the country.

For your consideration;

The name of the country Turkey (as "Türkiye" in Turkish )has been derived from the community named TURKS.

The TURKS had came from middle Asia and established a civilization in Anatolia.

The most believed tale about the origins of the name of the TURKS is the name indicates that the Turks are coming (-turemek, turuk, turk) from the wolves of mid-asia.
