Deer feed in open habitats such as meadows and clearcuts, retreating to more secure areas, such as thickets and closed canopy forests, to rest and chew their cud. Deers can also shed there antlers once a year so they can feel more refreshed. Deers typically sleep under bushes, and they have an lifespan of up to 6 years.

Deer's during the winter often travel as a pact as a family so they can navigate safely. Extensive clearing of land, unregulated hunting, and loss of habitat brought the white-tailed deer population to a record low by the late 1800’s. Before deers population have been really low, but now there are laws which prohibit hunting deers in certain places, which can help bring the population higher.
