Quick Answer
Deer change their feeding patterns during winter in response to harsh weather conditions and limited food availability. They shift to more energy-rich foods and adapt to conserve energy. This helps them survive the cold temperatures and scarce resources.
Winter Diet Shift
White-tailed deer in New Hampshire typically consume more fibrous plants like twigs, buds, and sap during winter. However, when possible, they prefer to feed on energy-rich foods such as acorns, beechnuts, and apples. In one study, deer were found to consume up to 75% of their winter diet from deciduous tree species.
Adaptation Strategies
Deer employ various strategies to conserve energy during winter, including reducing activity levels, altering their daily routines, and relying on stored fat reserves. A study in New Hampshire found that deer reduced their daily activity by 30% during the coldest months, allowing them to conserve energy and maintain body weight. Additionally, deer have been known to use existing food sources efficiently, making the most of the limited resources available.
Habitat Selection
Deer in New Hampshire often concentrate on specific habitats that provide reliable food sources during winter, such as areas with high concentrations of coniferous tree species. These areas typically offer a more consistent food supply and better protection from harsh weather conditions. For example, deer may prefer to feed in areas with dense coniferous cover, such as young pine plantations or stands with a mix of conifers and deciduous species.
