冬天照样活泼的鹿肯定是有的。 但网上有这样的介绍：
Deer don't hibernate. In the winter they will however sleep longer hours and generally restrict excess movement, meaning they'll stay closer to 'home'. This way, they can preserve energy as food supplies are lower in winter and they're using energy to keep warm.
Deer species do not hibernate in any way. White-tailed deer 'yard up' which means they avoid deep snow by finding groves of evergreens such as hemlock trees that can hold up some of the snow, allowing them to walk better underneath. The deer don't eat very nutritiously during this lean peroid, but they do eat what browse is available, and add bark and othe lower nutrition foods to their diet. Mostly they rely on fat stores and move less. Often they lie in the sun on winter days on edges of woods to warm up, saving energy. |
