The Barn Owl appears to be a more opportunistic feeder in the southern Bahamas than on the North American continent. Although rodents are the predominant item of diet in both places, samples of food remains from the islands contain a higher proportion of non-rodent material, especially of birds, than do continental samples. These results probably reflect the lower abundance of rodents on islands. Skulls representing new locality records for two species of birds (Porzana carolina and Spindalis zena) and two species of bats (Lasiurus sp. and Artibeus jamaicensis) are part of the skeletal debris collected at feeding sites of Barn Owls in the southern Bahamas.
