476. Mallards at the Ice Pond
Monhegan Island Spring Warbler Walk
The male birds have a bright green head, while the female's is light brown. The Mallard lives in wetlands, eats water plants, and is gregarious. It is also migratory. The Mallard is the ancestor of all domestic ducks, and can interbreed with other species of genus Anas. This interbreeding is causing rarer species of ducks to become genetically diluted.
