Doves are stocky birds with short wings and long tails. They forage on the ground, picking seeds and fruit with jerky steps and a bobbing head. Mourning Doves make a mournful cooing sound that can sound somewhat like an owl.
Members of the family Paridae, chickadees and titmice are small perching birds with strong feet. They also have short thin bills used for gleaning insects and seeds. Both nest in cavities and will sometimes use bird boxes.
