The forest canopy is home to the red tree vole and the northern flying squirrel. Several species of birds nest in the dead snag trees, including ospreys and spotted owls. Further down, under the canopy, animals such as bats and birds find shelter in the bark of the trees. You may hear the whistling call of a varied thrush, the shriek of a Steller's jay or the hoarse croak of a raven. In the understory, winter wrens and small mammals make their homes.
Gray squirrels search for acorns around the tanoak trees.
Along the edges, where the dark forest meets the river, you will find abundant wildlife. These areas get more sunlight and support plants that many of the animals use for food. You may see a black bear dining on blackberries, or a blacktail deer nibbling on tender willow leaves. The edges also support a healthy population of small mammals such as brush rabbits and deer mice. These become prey for the predators, such as the gray fox and bobcat.
