White-tailed Deer have long, slender legs, prominent ears, and large liquid brown eyes set off against thick white eye rings. Whitetails have a shiny black nose contrasting with a whitish nose band. The chin is white and edged on either side with a wide band of dark hair. The throat area is also white or grayish.
The deer’s prominent ears are edged in a dark color contrasting with white hair on the inside. The ears are often in motion; they can swivel independently of each other to capture sound from multiple directions and pinpoint the sound’s exact location.
The deer’s underparts, including its belly and the inner portions of its upper legs, are white. The rump and underside of the tail are also white. When alarmed, the deer flashes its tail, and the white hairs on its rump flare out, giving rise to the name “white-tail.”
