The chestnut-backed owlet (Glaucidium castanotum) (often misspelled Glaucidium castanonotum), [3] is an owl which is endemic to Sri Lanka. This species is a part of the larger grouping of owls known as typical owls, Strigidae, which contains most of the smaller owl species. This species was formerly considered to be a subspecies of the jungle owlet.
The chestnut-backed owlet is small and stocky, measuring 19 cm (7.5 in) in length. It resembles the jungle owlet in shape, size and appearance but the upperparts, scapulars and wing coverts are mainly chestnut brown, with darker barring. The underparts are white with blackish shaft-streaks. [4] The facial disc is mainly brown and the eyes are yellow. There is a white neckband. Sexes are similar in appearance, with no sexual dimorphism.
The chestnut-backed owlet is a common resident bird in the wet zone forests of Sri Lanka, and can be seen easily at sites such as Kitulgala and Sinharaja. Historical reports of its distribution by Legge include many parts of the southern half of Sri Lanka, especially the hills and the wet-zone low country extending to the outskirts of Colombo. In recent times, its range has shrunk greatly, and it is now found sparingly in the remaining forests of the wet zone and the adjoining hills at altitudes of up to 6,500 ft (2,000 m) above sea level. [4]
This species is diurnal and is frequently seen in the day, especially in the evening. The flight is deeply undulating. It can often be located by the small birds that mob it while it is perched in a tree. It frequents tops of tall trees, usually on steep hill-sides and hence is often missed. [4] It feeds mainly on insects, such as beetles, but also captures mice, small lizards, and small birds mostly when the young are being fed. [4] The call is a slow kraw-kraw and carries for a long distance. [4] It nests in a hole in a tree, laying two eggs.
In Sri Lanka, this bird is known as Pitathabala Vana-Bassa (පිටතඔල වන බස්සා in Sinhala).
The Sri Lanka whistling thrush is a whistling thrush in the family Muscicapidae. It is a resident endemic bird in Sri Lanka.
The Sri Lanka blue magpie or Ceylon magpie is a brightly coloured member of the family Corvidae, found exclusively in Sri Lanka. This species is adapted to hunting in the dense canopy, where it is highly active and nimble. Its flight is rather weak, though, and is rarely used to cover great distances. In spite of the Sri Lanka blue magpie's ability to adapt to the presence of humans, it is classified as vulnerable to extinction due to the fragmentation and destruction of its habitat of dense primary forest in the wet zone of southern Sri Lanka.
The pearl-spotted owlet is a small bird of prey found in sub-Saharan Africa. They belong to the Strigidae family, otherwise known as the typical owls or the true owls, which contains most species of owl. As part of the genus Glaucidium, or pygmy owls, they are commonly referred to as 'owlets' due to their diminutive size. Pearl-spotted owlets are brownish and heavily spotted white, with two distinct black false 'eyes' at the back of their head. They are often confused with an African barred owlet.
The collared scops owl is an owl which is a resident breeder in south Asia from northern Pakistan, northern India, Nepal, Bangladesh, the Himalayas east to south China, and Taiwan. It is partially migratory, with some birds wintering in India, Sri Lanka and Malaysia. This species was formerly considered to be included within what is now separated as the Indian scops owl.
The brown wood owl is found in India, Bangladesh, Sri Lanka, Indonesia, Taiwan, and south China. The brown wood owl is a resident breeder in south Asia. This species is a part of the family of owls known as typical owls (Strigidae), which contains most species of owl. It belongs to the earless owl genus Strix.
The vernal hanging parrot is a small parrot which is a resident breeder in the Indian subcontinent and some other areas of Southeast Asia. It undergoes local movements, driven mainly by the availability of the fruit, seeds, buds and blossoms that make up its diet. They frequent the banyan tree for the fruit and plantain trees for the nectar from the flowers.

The Sri Lanka spurfowl is a member of the pheasant family which is endemic to the dense rainforests of Sri Lanka. In Sri Lanka, this bird is known as haban kukula - හබන් කුකුලා in Sinhala.
Pygmy owls are members of the genus Glaucidium. They belong to the typical owl family, Strigidae. The genus consists of 29 species distributed worldwide. These are mostly small owls, and some of the species are called "owlets". Most pygmy owl species are diurnal, meaning they are most active during dawn, dusk, and daytime, and they mainly hunt large insects and other small prey. While primarily prevalent in North American countries—including the United States, Canada, and Mexico—Pygmy owls are considered threatened subspecies under the United States Endangered Species Act. More specifically, these owls can be found lurking in the mountain ranges of western United States territory, including California.
The jungle owlet or barred jungle owlet is native to the Indian Subcontinent. The species is often found singly, in pairs or small groups, and they are usually detected by their calls at dawn and dusk. There are two subspecies, with that found in the Western Ghats sometimes considered a full species.
The Albertine owlet is a small species of small owl in the family Strigidae, native to the Albertine Rift montane forests.
The collared owlet, also known as the collared pygmy owl, is a species of owl in the family Strigidae. Its natural habitat is submontane and montane forests with open spaces and is distributed throughout oriental Asia. It is the smallest owl in Asia, at 15 cm (5.9 in) and 60 g (2.1 oz).
The African barred owlet is a species of small owl in the family Strigidae found in much of southern, central and eastern Africa. The taxon may be four species rather than a single species.
The chestnut owlet is a subspecies of owl to the African barred owlet in the family Strigidae. It is found in west and central Africa in two allopatric subspecies that possibly could be classified as separate species.
The Asian barred owlet also known as the Cuckoo owlet is a species of pygmy owl native to the forests and shrublands of mainland Southeast Asia to the foothills of the Himalayas of northern Pakistan. It is a smaller owl, measuring 22–25 cm (8.7–9.8 in) making it one of the larger pygmy owls. They are primarily insectivorous but will eat lizards, small rodents and birds as well.
