The mallard is our most common duck, found in all
flyways. The males are often called "greenheads."
The main wintering area is the lower Mississippi basin,
and along the gulf coast, but many stay as far north
as open water permits.
Flocks
often feed in early morning and late afternoon in
nearby harvested fields, returning to marshes and
creeks to spend the night. The flight is not particularly
rapid. Hens have a loud quack; the drak's voice is
a low-pitched kwek-kwek.
