Cebus capucinus September 16, 1956 Barro Colorado Is., Canal Zone I saw one descend from trees and go under A-2M house to reach through wire to get old bananas. "Juan", a pet of Wilman (photographer), was in this cage yesterday. Perhaps the two or three had been released earlier by Wilman. In afternoon a half grown young seen in trees near Chapman House. September 18, 1956. About 4 p.m. saw one riding on back of another near Chapman house; apparently mother or young. September 23, 1956. Apparently the dense foliaged tree 50 yds. SSE of Chapman House being used as food tree, for Cebus seen there almost every day recently, at least 3 there this morning about 6:30 a.m. Also fairly common along the trails - saw 2 or 3 times more often than Alouatta. October 2, 1956. Still common near clearing. In a.m. about 9 saw 3 (±) in broad leaved tree 100' SSE of Chapman House - favorite tree at this season.
