The Tufted Titmouse (Baeolophus bicolor) is the most commonly found bird in the park. It can be found in mature deciduous woods. It feeds on insects and seeds, and often forages in groups or pairs. They create their nests of mosses, hair, grasses, leaves, cotton, bark strips, or other similar materials in natural caviites. In late winter or early spring, familial flocks break up and the male starts singing to defend his breeding territory of 2-5 acres. They are gray birds with black on the forehead and a white or buff-colored chest. Adults are about 5-6.5 inches long, with a wingspan of about 9.75 inches. Their song is commonly heard, a droppnig whistle of "peter peter peter peter".
