Alouatta seniculus (Linnaeus)

We heard howlers night and day throughout the course of our fieldwork at Paracou. Despite the audible evidence of their continuous presence, however, we seldom caught more than fleeting glimpses of this locally persecuted species. The few groups surviving in our study area never closely approached our camp, and they seldom ventured within the radius of our daily activities except to visit fruiting fig trees and other transient resources.
