Similar Species Fulvous Whistling-Duck D. bicolor (L 18-20 in) has similar habits and posture to Black-bellied. However, it is less colorful overall, plumage being rather uniformly orange-brown, darkest on crown, nape, and back. Bill and legs are blue-gray and wings appear uniformly dark in flight. A tropical species at the northernmost limit of its range in southern Texas. Seen only occasionally in region covered by this book, typically during post-breeding dispersal in late spring.


Discussion Colorful long-necked, long-legged duck that often adopts an upright posture, which adds to impression of it being a nervous bird; indeed, typically it is extremely wary. Note also the proportionately long wings. Often perches on branches or rocks, and nests in tree holes. Highly gregarious outside the breeding season. It feeds on aquatic plants, grass, and cereals, as well as freshwater invertebrates; typically it feeds at night. Sexes are similar.
