The Ringed Necked duck is native to North America and is often referred to as the Ringed Bill Duck as the ring around the neck is less conspicuous than the light ring around the bill. The drake is a predominantly black and white bird although a close approach reveals him to have a purple sheen on the head and neck. The female is overall brown in color. These birds are hardy and are easy to keep in captivity. They are compatible with other waterfowl species and can do well in mixed collections. The males acquire their adult plumage their first Fall and can breed their first Spring. Nests are made on the ground under natural cover or in a nesting box. Clutches consist of 6-10 eggs and are incubated for about 26 days. The ducklings of this species are not difficult to raise.
