Goldeneye dive underwater to catch invertebrates and feed on aquatic plants.
Goldeneyes live in lakes and rivers near forested areas. They are late migrants in the fall and can overwinter in the open water of large bays and estuaries.
Male goldeneye have black heads and females goldeneye have brown heads.
These birds lay eggs in nesting boxes or the nests of other birds. It is not uncommon for a young goldeneye chick to be raised by another species of duck or another female goldeneye.
