White-tailed Deer - Diet

White-tailed deer are herbivores and are considered concentrate selectors. Their diet includes many different types of vegetation and varies greatly with the seasons and the region in which they inhabit.  White-tailed deer mostly depend on browse but also feed on forbs, hard and soft mast and grasses.

In agricultural regions, White-tailed deer may feed heavily upon crops, such as corn, soy beans and alfalfa, if they are present. During the harsh winters of northern regions White-tailed deer depend on browsing the twigs and buds of woody shrubs and trees while the supply of higher quality feed is scarce.

White-tailed deer are ruminants, so they may consume at a high rate and retreat into safer cover to finish digesting their food.  This helps them avoid predation.  They also produce a tannin binding saliva which helps them digest things easier than other herbivores.  They may still select for things with lower tannin content.
