We studied the habitat, breeding, social behavior, and vocalizations of the Colombian endemic Cauca Guan (Penelope perspicax) in the Otún Quimbaya Sanctuary for Flora and Fauna in Risaralda Department on the west slope of the Central Andes. This guan inhabited natural forests as well as forest plantations, where it fed mostly on fruits and foliage high in the trees and captured invertebrates on the ground while following army ants (Labidus praedator). Based on the frequency of vocalizations, wing-whirring, and detection of chicks, we concluded that breeding occurred from January to June, coinciding with a peak of fruit abundance, which was followed by a molting period. Clutch size was two, and the young remained with their parents until subadult age, i.e. ca. one year after hatching. The guans lived in small family groups, but on rare opportunities as many as 30 individuals flocked together. We did not detect aggressive behavior, territoriality, fixed roost sites, or fixed foraging routes. Although our results suggest that the Cauca Guan tolerates disturbed habitats, and that this population is carrying out all of its vital activities within the Sanctuary, we deem it important to consider the effects of fragmentation, isolation, and hunting as continuing threats to this species.
