North American porcupine
Bats are infrequently reported as prey in most of the range but an unusually close association was detected in Valdosta, Georgia, where most of the prey, 65% of pellet contents and 37 total bats, were southeastern myotis. Barred owls are also known predators of both eastern spotted and western spotted skunks, the latter estimated to weigh when taken. Much larger mammals are sometimes recorded in the foods of barred owls, but there are few details known about the age, condition or circumstances (i.e. they may have been consumed as carrion or, perhaps more likely, young or infirm specimens were taken). Some such prey species recorded have included the Virginia opossum, the North American porcupine, the striped skunk and the domestic cat. Adults of all these species are known to count amongst the prey of great horned owls which is better suited than barred owls to take particularly large prey given its powerful morphology.
