Mallard
Length--24
Weight--2¾ lbs.
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 waters 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
drake's voice is a low-pitched kwek-kwek.
