Barn Owl - That heart-shaped face is characteristic of barn owls. This species is not only the most widespread owl species, but also one of the most widespread of any bird species. It also has over 22 other names, including ghost owl, death owl, hissing owl and delicate owl.
Eastern Screech Owl - Found throughout eastern North America from Canada to Mexico, this short and stocky species has a misleading name. It doesn't actually screech, but makes a descending tremolo call. Still, it is usually heard rather than seen. photo: Shutterstock
