 In the United States, screech owl pellets have contained bands from a tufted titmouse, black-capped chickadee, and American goldfinch.In 1966, a golden eagle pellet in Oregon was found to contain a band placed on an American wigeon four months earlier, and away in southern California.The hair, bones and other body parts (such as limbs, skin fragments, and even faeces) of rodents found in owl pellets may carry viable rodent viruses and bacteria.
