A puma/black bear hybrid was reported in California newspapers in 1904. To be exact, the report refers to cinnamon bear. The Cinnamon Bear is usually treated as a subspecies (cinnamomum) of the Black Bear (Ursus americanus). However, since cinnamomum occurs in regions where U. americanus and U. arctos overlap, and since it resembles the latter in coat color while being classified as a subspecies of the former, the possibility should be considered that it may be derived from hybridization between U. americanus and U. arctos, especially given that it is known that such hybrids have occurred both in the wild and in captivity.
The following article was originally published in the Stockton Record, but the transcript as it appears here was taken from page 4, column 3, of the May 21, 1904, issue of the Mariposa Gazette (source):
This cross, if accurately reported, would interfamilial (Felidae × Ursidae).
Pumas (Felis concolor), also known as mountain lions or cougars, come into potential breeding contact with bears over much of North America.
