Winter is a also great time to create a brush pile. By collecting yard debris like branches, twigs, and fallen leaves, you can create cover for birds and small mammals, like rabbits, and at the same time offer a hibernation place for some species of turtles, salamanders, and insects. The mourning cloak butterfly, for example, overwinters as an adult in woody debris and may use your brush pile. Many butterfly species and other insects will lay their eggs or overwinter as pupae in brush piles. Fallen leaves can also be used as mulch to protect plant roots from freezing temperatures, or composted and used as organic fertilizer next summer.
Water can be scarce for wildlife in winter when natural sources are frozen.
While most creatures are seeking drinking water, birds are also looking for bathing water. Bathing helps birds to stay warm by keeping their insulating feathers in tip-top condition. Keeping your bird bath clean and free from ice will help birds and other creatures to survive the winter. Heated bird baths, which keep the water just warm enough to keep from freezing and use little electricity, are also available. Winter is the time for backyard wildlife watchers to brush up on their identification skills.
