This is the second of a four part series on our province’s most resilient animals. You can find out more about mammals that are active through the winter here.
You may have assumed that the mammals you don’t see during the winter are hibernating, but that isn’t always the case. In fact, some mammals use an ‘in between’ strategy that involves a lot of deep sleeping with some activity to pass the time in colder weather. Continue reading →

This year, our focus is on those animals that brave the challenges of our cold and snowy climate. This is the first of a four part series on our province’s most resilient animals. Continue reading →

Snake dens are usually located in rock crevices or caves, or small mammal burrows. The temperatures within hibernacula remain just above freezing during the winter because of the insulating effects of the earth. Continue reading →
