The bay owls are barn owls of the genus ''Phodilus'', subfamily Phodilinae. Bay owls appear similar to other barn owls; they are generally smaller, have ear-like feather tufts, and have a more divided and U-shaped facial disk. Most classification schemes recognize three species in this genus: the oriental bay owl (''Phodilus badius''), the Sri Lanka bay owl (''Phodilus assimilis'') and the Congo bay owl (''Phodilus prigoginei''). ''P. prigoginei'' is not well known and was initially considered a subspecies of ''P. badius''; today, however, it is not clear whether the African species would not be better placed in ''Tyto'' or a monotypic genus. It is similar to the other ''Phodilus'' species in being smaller than typical barn owls, and having the more U-shaped facial disk; however, the ear-like feather tufts are hardly visible. An apparently extinct population from Samar Island might constitute a fourth species, but the only known specimen has been lost. ==References== *Bruce, M. D. (1999): Family Tytonidae (Barn-owls).
