Dendrocygna autumnalis

Black-bellied Whistling-Duck
copyright Richard Ditch
Length: 21 in. (53 cm)
Usually seen in marshy areas with trees, along forested streams, and on muddy beaches, this large duck also grazes in flooded rice fields, pastures and grassy golf courses. The nest is in a tree cavity high above the ground, but occasionally they nest on the ground among dense grasses in a marshy area. Several females will sometimes dump their eggs into a common nest, and up to 100 eggs have been found in a single nest. The most common foods are seeds, grain and some snails and insects. The four-digit banding code is BBWD.
