The Birds of Mount Diablo's Woodland

By Jenn Roe

The Oak woodland habitat attracts and assortment of birds where oaks (the dominant tree) and other vegetation offer a variety of food to suit a range of avian eating habits: acorns and other seeds, berries, leaves, wood, sap, roots and pollen. These plant foods attract insects and other edible creatures that add to the list of menu items.

Many birds find shelter here. Some nest in tree cavities, while other species make their home in the canopy of leaves and branches, or under the protection of understory plants.
