Birds such as broad-winged hawks, cardinals, snowy owls, and pileated woodpeckers are also found in this biome. Mammals include white-tailed deer, raccoons, opossums, porcupines, and red foxes. Animals that live in the temperate deciduous forest must be able to adapt to the changing seasons. Many understory plants have leaf adaptions to cope with low light levels, and the need to exploit moving flecks of light on the forest floor.
