Remaining Active
Winter can be very challenging for animals.
Some of the same problems which face plants in winter also
face animals: freezing temperatures, lack of water, and fewer
hours of sunlight during the day.
Many seed-eating birds stay and brave out the cold winter
months. The blue tit in the photograph above makes good use of
the nuts in a bird feeder.
In order to remain active, animals need a
good food supply throughout the winter. Large herbivores, such
as deer, do not get cold very quickly and they can usually
find enough food during the winter months. Instead of eating
grass and herbs which may be covered in deep snow, they may
have to eat the bark of trees and the branches and shoots of
bushes.
Carnivorous mammals and birds may bunt for
herbivores which are still active. For example, foxes can
still find mice, voles or rabbits to eat in winter. If,
however, a carnivore specializes in insects (an insectivore)
it may find no food at all in the winter months.
