Range. - Tropical America, north in the Rio Grande Valley to southern Texas.

These peculiar long-legged Ducks are very abundant in southern Texas during the summer months. They build their nests in hollow trees, often quite a distance from the water. They lay their eggs upon the bottom of the cavity with only a scant lining, if any, of feathers and down. They are very prolific breeders, raising two broods in a season, each set of eggs containing from ten to twenty. These eggs are creamy or pure white, size 2.05 x 1.50. The first set is laid during the latter part of April or early in May, and fresh eggs may be found as late as July. They are especially abundant about Brownsville and Corpus Christi, Texas. Data. - Hidalgo, Mexico, May 29, 1900. Ten eggs in a hole in an old elm tree on side of lake in big woods near town. Eight feet from the ground. Collector, F. B. Armstrong.
