buff or rufous. The feet and toes, which are small and weak, are brownish gray to reddish brown. Woodcocks have large eyes located high in their heads, 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, prehensile 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. Distribution and habitat Woodcocks inhabit forested and mixed forest-agricultural-urban areas east of the 98th meridian. Woodcock have been sighted as far north as York Factory, Manitoba, and east to Labrador and Newfoundland. In winter, they migrate as far south as the Gulf Coast of the United States and Mexico. The primary breeding range extends from Atlantic Canada (Nova Scotia, Prince Edward Island, and New Brunswick) west to southeastern Manitoba, and south to northern Virginia, western North Carolina, Kentucky, northern Tennessee, northern Illinois, Missouri, and eastern Kansas. A limited number breed as far south as Florida and Texas. The species may be expanding its distribution northward and westward. After migrating south in autumn, most woodcocks spend the winter in the Gulf Coast and southeastern Atlantic Coast states. Some may remain as far north as southern Maryland, eastern Virginia, and southern New Jersey. The core of the wintering range centers on Louisiana, Mississippi, Alabama, and Georgia. Based on the Christmas Bird Count results, winter concentrations are highest in the northern half of Alabama. American woodcocks live in wet thickets, moist woods, and brushy swamps. Ideal habitats feature early successional habitat and abandoned farmland mixed with forest. In late summer, some woodcocks roost on the ground at night in large openings among sparse, patchy vegetation. Courtship/breeding habitats include forest openings, roadsides, pastures, and old fields from which males call and launch courtship flights in springtime. Nesting habitats include thickets, shrubland, and young to middle-aged forest interspersed with openings. Feeding habitats have moist soil and feature densely growing young trees such as aspen (Populus spp.), birch (Betula spp.), and mixed hardwoods less than 20 years of age, and shrubs, particularly alder (Alnus spp.). Roosting habitats are semiopen sites with short, sparse plant cover, such
