Physical Characteristics
The American Woodcock has a plump body, short legs, a large, rounded head, and a long, straight bill. Adults are 10 to 12 inches (25 to 30 cm) long and weigh 5 to 8 ounces (140 to 230 g). Females are considerably larger than males. The bill is 2.5 to 2.75 inches (6.3 to 7.0 cm) long.
The plumage is a cryptic mix of different shades of browns, grays, and black. The chest and sides vary from yellowish white to rich tans. The nape of the head is black, with three or four crossbars of deep buff or rufous. The feet and toes, which are small and weak, are brownish gray to reddish brown.
Woodcock have large eyes located high in the head, and their visual field is probably the largest of any bird, 360° in the horizontal plane and 180° in the vertical plane.
The Woodcock uses its long bill to probe in the soil for food, mainly invertebrates and especially earthworms. A unique bone-and-muscle arrangement lets the bird open and close the tip of its upper bill, or mandible, while it is sunk in the ground. Both the underside of the upper mandible and the long tongue are rough-surfaced for grasping slippery prey.

Famous quotes containing the word physical:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
