Ecosystem and habitat
These Asian barred owlet species have moderate forest dependence. They normally occur in altitudes from 0 to 2700 meters. Their artificial ecosystems and habitats include rural gardens, orchards and plantations.The natural ecosystems and habitats of these Asian barred owlet species include open oak and pine forests, tropical and subtropical moist lowland forests, evergreen forests, temperate forests, moist montane forests and moist shrublands.
Diet and feeding behavior
The diet of Asian barred owlet consists mainly of large insects. Beetles, grasshoppers, crickets, mantids, locust, cicadas and termites are their primary food.These Asian barred owlets are known to prey on frogs, lizards, rodents and small birds. They catch their prey in flight. Occasionally, they forage on the ground or glean their prey from the foliage and branches of trees.
Reproduction and breeding habits
The breeding season of the Asian barred owlet species is during April and May in India. The laying season is from April to June in Nepal. They are monogamous and territorial.The nesting sites of these owlet species include tree cavities and old woodpecker holes. The clutch may contain four to seven eggs. The female does most of incubation and the male feeds the female.
The Asian barred owlet chicks hatch out in four weeks. The female broods the chicks for a week and the male provides food. Later both the parents feed and care for the young. The nestlings fledge 30 to 34 days after hatching.
Migration and movement patterns
These Asian barred owlet species are non-migratory, resident birds. The birds in higher altitudes move to lower levels and plains during winter.Post breeding, the juvenile owlets may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
