Abstract
"Recent field work in Trinidad and a review of museum specimens has provided additional information on the poorly known Chapman's swift, Chaetura chapmani. Details are given on a color change associated with plumage wear and also measurements and ranges of the two recognized subspecies. Chaetura c. chapmani is a sedentary breeder in the area from Panama to the mouth of the Amazon River. It breeds in the early part of the rainy season, which is during the northern spring and summer. Chaetura c. viridipennis appears to breed south of the equator in southern Brazil during the northern winter and to migrate to Colombia during the northern summer months. Observations on one nest of Chapman's swift found in Trinidad are presented. The nest, clutch size, incubation period, and appearance of the young are very similar to those of other congeners. Data are presented on the weight and molt of adults and juveniles of this species in Trinidad. A wing-clapping display is described which differs somewhat from that described for some other species of Chaetura. Notes on the ecology of C. chapmani in Trinidad are presented"--P. 13-14.
