Kangaroo mice are nocturnal, and are most active in the two hours following sunset. They are believed to hibernate during cold weather. Although mitochondrial data indicate that the clades appear to be in approximate genetic equilibrium and have not suffered any extreme bottlenecks over time, there is still concern for the survival of smaller ...

“Whenever there’s a winter weather advisory, we always know that we’re in for some hurting as far as how many animals we’re bringing in,” said Jane Macmurchy of Animal Charity of Ohio.
The mice are born without hair (naked) and live nearly two years. They hibernate an estimated 7–8 months - from September or October through late May or early June [ 6 ] - building themselves a soft vegetation nest, typically at a location with a northerly aspect. [ 7 ]

When the temperatures begin to drop, snakes go into a state called brumation.This event acts as a type of hibernation for cold-blooded animals. “Cold temperatures cause reptiles and amphibians ...
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
