One of North America's most ornate ducks; males have an iridescent green-and-purple crested head, complex face patterning, chestnut breast, and colorful bill. Females are elegantly marked in brown and grey. Nests in tree cavities along forested waterways. Recovered strongly from near-extinction after 1918 legal protection.
