Azuero Howling Monkey
Alouatta coibensis trabeata Lawrence, 1933
CR B1+2abcde, C2a

As its name would suggest, the Azuero howling monkey is known principally from Azuero Peninsula in western Panama, but its range apparently also extends northwestward to the Burica Peninsula as well. The Azuero Peninsula has been largely deforested to make room for agriculture and ranching, and the only tropical forests of any appreciable size are those of the 34,092-hectare Cerro Hoya National Park on the western side of the peninsula. Hunting, unfortunately, is also a threat to wildlife in this region, and howling and spider monkeys, due to their large body size, are among the first species to disappear from an area after hunters move in. Therefore, it is not surprising that both the howling and spider monkey subspecies restricted to the mountainous parts of the Azuero Peninsula are considered critically endangered. The Azuero howling monkey has not been seen in the wild by scientists for more than a decade, and could possibly be extinct. Searches should be undertaken to locate any remaining populations.
