Deer are even-toed ungulates in the Cervidae family. At birth, fawns are rust-colored with white spots. The coat of adult deer can differ from seasons. In the summer their coat reddish-brown and in the fall their coat is a dark brown color. The area under the tail, the belly, chin, and the throat are always white. Ideal habitat for deer is forest edge rather than dense, old-growth forest. They thrive in agricultural areas interspersed with woodlots and riparian habitat. Many populations of deer flourish in urban areas. Deer browse on leaves, stems, and buds of woody plants all year long. Preferred species of plants vary considerably in quality and regional availability. In urban environments, they will feed on gardens, decorative plants and lawns. Deer-vehicle strikes are the biggest threat to the human safety that is posed by deer. In addition to the economic loss in damaged vehicles, 100 to 200 people in the US die each year along with thousands who are injured by hitting or avoiding deer.
