Dogwood berries do not stay on the tree as long as other fruits and berries. By mid-winter, dogwood trees are usually bare. Bluebirds do feed on other berries such as pokeberries, Virginia creeper, sumac, rose hips, mistletoe, hackberry, cedar, holly and many other wild and ornamental dried fruits and berries.
