The Pale-winged Trumpeter (Psophia leucoptera), also known as the White-winged Trumpeter, is a species of bird in the Psophiidae family. It is found in the southwestern Amazon Basin of Brazil in a contiguous range between three river systems, including the Amazon, and into the upper reaches of the basin into parts of central Bolivia, and in eastern Peru. Like the Dark-winged Trumpeter, it is restricted to the southern Amazon Basin. The other member of the trumpeter family, the Grey-winged Trumpeter, is restricted to the northern Basin and the Guyanas.
The Pale-winged Trumpeter's habitat is tropical moist lowland forests (BirdLife International 2004).
Its reproductive behavior is the best known of the trumpeters'. Groups of adults defend a territory together. Several males mate with the dominant female, the dominant male doing so most often. She lays an average of three eggs in a hole in a tree, where both males and females incubate. The young hatch covered with thick, dark, cryptically patterned down. Soon afterwards, they jump down to the ground and follow the adults (Holyoak and Colston 2003).
