That is as may be  but Indigenous modern horses died out in the New
World at the end of the Pleistocene, about 12,000 years ago, and thus
were absent until the Spanish brought domestic horses from Europe,
beginning in 1493.

That does not make them " part of the natural inhabitants of this region "
