The bay owls (Phodilus) are a genus of Old World barn-owls. The defining characteristics of bay owls are their smaller bodies, in comparison to other barn owls, and their U- or V-shaped faces.[1] These owls can be found in South to Southeast Asia, and parts of central Africa within forest and grassland ecosystems.[1]

Taxonomy and systematicsEdit

The genus Phodilus was erected by the French zoologist Isidore Geoffroy Saint-Hilaire in 1830.[2] Some taxonomists place two species in the genus, while others include three.[3] The name is from the Ancient Greek phōs for "light" or "daylight" and deilos for "timid" or "cowardly".[4] Most classification schemes recognize three extant species in this genus:[5]

DescriptionEdit

Although bay owls are typically smaller, they bear resemblances to other 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 attributed with U-or V-shaped faces.[1][3] Their wings are rounded and their tail is chestnut-colored, 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 color and their underparts are often a pale yellowish-brown, with speckles of blackish-brown coloring.[3]

Distribution and habitatEdit

The bay owl can be found in regions from India to Southeast Asia and Indonesia, as well as parts of central Africa.[1] It is uncertain where the ancestors of these avians lived as the phylogeny of all species of bay owls has not been analyzed.[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 meters off the ground.[1] They are most vulnerable in this state and not very alert.[1]
