Facts about this animal
The wood duck is a small perching duck with a body-weight of about 680-860 g in males and about 540 g in females. It is 47-54 cm long and has a wingspan of 66-73 cm. The tail is rather long.
The drake has a glossy, colourful plumage and a sleek crest. Its bill is red-coloured at the base. Head pattern and bill colour are retained in the drab eclipse plumage. The female has a short crest and a dull grey-brown plumage with a large teardrop-shaped eye patch.
The female lays 13 to 15 white eggs in a tree cavity often near or overhanging water, and incubates them alone for 30 days. Because natural cavities for nesting are scarce, the wood duck often uses nest boxes provided for it. If nest boxes are placed too close together, many females lay eggs in the nests of other females. These "dump" nests can have up to 40 eggs.
