ILLUSTRATION ON ITS WAY

Wood Duck

Aix sponsa

A Wood Duck drake in full color reads more like a costume than a wild bird: an iridescent green-and-purple crest, a red eye, and a body patterned in chestnut, buff, and white in combinations no other North American duck attempts. The female is quieter but distinctive too, marked by a white teardrop around the eye that stands out even in poor light.

The nest sits nowhere near what most people picture for a duck. Wood Ducks nest in tree cavities, sometimes well up a trunk and often far from open water, and the ducklings make their first move in life a leap: jumping from the nest hole to the ground or water below within a day of hatching, bouncing largely unhurt thanks to how little they weigh at that age.

Tree cavities nearly cost the species everything, too. Habitat loss and unregulated hunting pushed Wood Duck numbers into serious decline by the early 1900s, and recovery took decades of hunting limits paired with a simple, effective fix: nest boxes, installed by the thousands across wetlands where old, cavity-riddled trees had become scarce.

A rising, squealing whistle from females (often rendered oo-eek), especially in alarmed flushing flight; males give a soft, thin whistle.
