Thebay owls (Phodilus) are agenus ofOld World owls in the familyTytonidae. The defining characteristics of bay owls are their smaller bodies, in comparison to thebarn owlsTyto in the same family, and their U- or V-shaped faces.[1] These owls can be found across southern Asia from southern India and Sri Lanka to Indonesia within forest and grassland ecosystems.[1]
The genusPhodilus was described by the French zoologistIsidore Geoffroy Saint-Hilaire in 1830.[2] Most taxonomists include two extant species in the genus; a third formerly included has now been transferred toTyto.[3][4] The name is from theAncient Greekphōs for "light" or "daylight" anddeilos for "timid" or "cowardly".[5]

TheItombwe owl (Tyto prigoginei) was formerly classified in this genus as the Congo bay owl, but morphological evidence shows that it is a member of the genusTyto.[3][4]
Although bay owls are typically smaller at 22–29 cm (8.7–11.4 in) long, they bear some resemblance to the barn owls.[1] Other characteristics of the bay owl are groupings of feathers that resemble ears, and a divided face disk.[1] Bay owls have also been described as having U-or V-shaped faces.[1][3] The wings are rounded; they and their tail are chestnut-brown, with a few narrow, dark bars.[6] Their tarsi, or leg/foot bones, are relatively short and fully feathered to the joint.[3] Their toes are yellowish-brown with pale claws.[3] Their throat has a creamy colour and their underparts are often a pale yellowish-brown, with speckles of blackish-brown.[3]
The bay owls can be found in regions from India to Southeast Asia and Indonesia.[1] It is uncertain where their ancestors lived as the phylogeny of all species of bay owls has not been examined.[7] These owls can be found in both forests and grasslands, but are fairly scattered in their distribution.[7] However, their primary habitat is within dense evergreen forests, where the owls may roost during the day in the opening of tree trunks or branches sheltered by palm tree leaves.[1] They are often found roosting no more than 2 m (6 ft 7 in) off the ground.[1] They are most vulnerable in this state and not very alert.[1]
