Breeding of the Gray-winged Trumpeter in French Guiana

Abstract

In French Guiana, a territorial group of Gray-winged Trumpeters (Psophia crepitans) laid three eggs in a cavity atop a Voucapoua vouacapoua snag, 13.5 m up. At least two individuals alternated incubation, as in White-winged Trumpeters P. leucoptera in Peru. One egg had a dead embryo, and the two nidifugous chicks disappeared in their first week. Some previous field records of nests or eggs are probably incorrect.
