This bird is long-legged like the last, but the plumage is entirely different, being of a general rusty color, including the entire under parts. The nesting habits and eggs are the same as those of the Black-bellied Duck, the white eggs being laid at the bottom of a cavity in a tree. They number from eight to (in one instance) thirty-two eggs in one nest. This species is nearly as abundant as the preceding in southern Texas.
