The Ashy-faced Owl is endemic to the island of Hispaniola, and is one of just two barn-owls (Tytonidae) present in the New World. It resembles the widespread Barn Owl (Tyto alba), which colonized Hispaniola in the 1970's, but is much darker overall, with a gray face. The Ashy-faced Owl shares many behavioral traits with the Barn Owl, hunting for small mammals in open areas at night and nesting in hollow trees, caves, and man-made structures. The two species are not known to hybridize. In the past, two subspecies of Barn Owl from the Lesser Antilles (T. a. nigrescens and T. a. insularis) have been included within Ashy-faced.
