There is only one species, but two subspecies, the northern bald eagle and the southern. There are also several races, but all belong to the same species.
The sub-races that belong to Mongoloids are East Asians, Southeast Asians, Central Asians, Arctic Native Americans, and Indigenous peoples of the Americas.
Human races are not biologically distinct enough to prevent interbreeding. All humans belong to the same species, Homo sapiens, so individuals of different races can have children together. The biological compatibility for reproduction is based on being the same species, rather than having the same racial background.

There are no known "alien races", so the question is more or less meaningless even if "animal characteristics" was defined well enough for us to tell.

As a species leopards are not endangered, but some races are. To see endangered races, check the IUCN Redlist.
