These mostly white owls have a very distinctive call that can be quite eerie and heard from far away. If you hear a very loud screech after the sun goes down, chances are it's a barn owl or family of barn owls. Their name comes from the fact that they are commonly found in barn attics, they also roost/nest commonly in tree cavities. Since their typical diet consists of rodents/small mammals, you will usually find them around open fields are spaces that have enough of those to sustain them. Since they hunt at night like most owls, they typically come out after sunset and it is rare to see them in daylight.
