Subspecies

Monotypic species

Genus

The genus Tyto includes all barn-owls (family Tytonidae) except for the bay-owls (subfamily Phodilinae, genus Phodilus) – that is, the true barn-owls, the grass-owls and the masked-owls collectively making up the subfamily Tytoninae. They are darker on the back than the front, usually an orange-brown colour, the front being a paler version of the back or mottled, although there is considerable variation even amongst species. Tyto owls have a divided, heart-shaped facial disc, and lack the ear-like tufts of feathers found in many other owls. Tyto owls tend to be larger than Bay-owls.

Physical charateristics

Male blackish grey above with white spots. Facial disc dusky to brownish, underparts buff with dark spots. Female darker and more spotted on underparts. Belly and legs all whtie,

Conservation

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
