White-tailed Deer
Odocoileus virginianus

Description: Size varies greatly; a small to medium-size deer. Tan or reddish brown above in summer; grayish brown in winter. Belly, throat, nose band, eye ring, and inside of ears are white. Tail brown, edged with white above, often with dark stripe down center; white below. Black spots on sides of chin. Buck antlers have main beam forward, several unbranched tines behind, and a small brow tine; antler spread to 3' (90 cm). Doe rarely has antlers. Fawn spotted.

Warning: The White-tailed Deer population has become a public-health concern with the onset of Lyme disease, which is transmitted by ticks carried by the deer.

Breeding: Reproductive season varies: first 2 weeks in November in north, January or February in south.

Habitat: Farmlands, brushy areas, woods, and suburbs and gardens.

Range: Southern half of southern tier of Canadian provinces; most of U.S., except far Southwest.

Discussion: Although primarily nocturnal, the White-tailed Deer may be active at any time. The animal usually beds down near dawn, seeking concealing cover. This species is a good swimmer. The White-tailed Deer is also a graceful runner, with top speeds to 36 mph (58 km/h), although it flees to nearby cover rather than run great distances. This deer can make vertical leaps of 8 1/2 feet (2.6 m) and horizontal leaps of 30 feet (9 m). The White-tailed Deer grazes on green plants, including aquatic ones in the summer; eats acorns, beechnuts, and other nuts and corn in the fall; and in winter browses on woody vegetation, including the twigs and buds of viburnum, birch, maple, and many conifers. The four-part stomach allows the deer to feed on items that most other mammals cannot eat. When nervous, the White-tailed Deer snorts through its nose and stamps its hooves, a telegraphic signal that alerts other nearby deer to danger. If alarmed, the deer raises, or "flags," its tail, exhibiting a large, bright flash of white; this communicates danger to other deer and helps a fawn follow its mother in flight.
