The White-tailed deer (Odocoileus virginianus)
is a mid-sized cervid. During the summer months they appear as brown or
reddish-brown and during the fall and winter months they appear as
greyish-brown. White is found on the throat regions along with around the eyes, nose, stomach, and under their tails. They
get their name “White-tailed deer” from their bright white underside of
their tail which they use as flagging in presence of danger.
White-tailed deer have paraxonic feet in which their second and third
metapodials are fused together to form their hoof. Sexual
dimorphism is present in this species because the males (bucks) have
antlers after their first year in which the females (does) do not. Each winter bucks cast their antlers and regrow a new set each spring. The new set is encased in velvet during the summer months while the antlers are growing and hardening. Typically
the new set is larger than the previous years. Bucks are generally
bigger than females and can weigh 60-130kg while does generally weigh
40-90kg. These weights highly vary among subspecies with the heaviest
being found in Canada and the smallest near the equator.
