Name: Barn Owl - Tyto alba
Other Common Names: Monkey-faced Owl; Ghost Owl; Golden Owl.
Subspecies: There are as many as 46 races of Common Barn owl recognized across the world. There is only one race recognized in North America. As many as 5 more are described from Central America (1 in the Bahamas, 1 in Cuba, 1 from the Isle of Pines, 1 from Hispanola, and 1 from Guatemala south to the Panama Canal). The ranges of these are not well defined and also need review so are not listed here. T. a. pratincola is found in S. W. British Columbia south and east through most of the U. S. (except some of the northern-central states) and Mexico. This is the largest race (physical size) of Barn Owl in the world.
