The Oriental Scops-owl is a small bird of prey with 9 subspecies.
The horned owl builds nests in tree holes, wall holes and other depressions to breed and raise offspring, and can generally raise 4-6 chicks in one breeding season. The breeding season in the Indian subcontinent is from February to May. During courtship, males and females will sing in duets. The male first sings near potential nesting sites, which are usually trees or wall holes. This species also uses nest boxes. They call by entering the hole and singing at the entrance. The female lays 3-4 white eggs per nest, which are placed on the ground of the nest. The female incubates alone, while the male provides food.
The global population size of the horned owl has not been quantified, but the species is reported to be regionally abundant (delHoyo et al., 1999), and global population estimates include: in China, about 10,000-100,000 breeding pairs and about 1,000-10,000 migratory individuals; in Taiwan, the migratory population averages less than 1,000; in Korea, the migratory population averages 100-100,000 breeding pairs and 50-10,000 individuals; in Japan, about 100-100,000 breeding pairs and about 50-10,000 individuals in migration; in Russia, about 100-10,000 breeding pairs and about 50-1,000 individuals in migration (2009). Trend reason: The population is suspected to be stable without any evidence of decline or major threats.
