About the size of the Collared Scops Owl. Sexes alike. This little owl is very like the last species in shape, size, and general apperance but it is chestnut on back, scapulars, and wing-coverts, and has white underparts marked with blackish shaft-streaks, and bars on the flanks. Some specimens have white spots on the outer scapulars. Irides bright yellow; feet pale yellow.It is shy and wary, and as it frequents the tops of tall trees, usually on steep hillsides, it is seldom seen. It is very diurnal in habits, often hunting and calling in broad daylight. The Mukalan Bassa feeds mainly on insects, such as beetles, but also captures mice, small lizards, and small birds, on occasion; most likely, the larger vertebrate forms of prey are taken only when young are being fed.The breeding season is from March to May, the eggs being laid on the bare wood in a hole in the trunk or limb of a tree. The two glossy white eggs measure about 35 × 28.2 mm.

This owl appears to have been fairly common in Legge's time in many parts of the southern half of the Island, especially the hills and wet-zone low country extending to outskirts of Colombo; but its range has undoubtedly shrunk very greatly since then, and it is now found sparingly in the remaining forests of the wet zone and adjoining hills up to 6,500 feet.

Distribution and habitat
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 up to 6500 ft above sea leve.

About the length of Common Coucal, but more slenderly built and with, proportionally, a much longer tail. Sexes alike, except that the female has white irides-those of the male being brown. This handsome bird cannot mistaken for any other species on the Sri Lankan list.It inhabits tall forest, and lives either solitary, in pairs, or in small flocks. It is shy and restless, a dweller in the tree canopy, where, like the last species, it cleverly threads its way through tangled twigs, creepers and foliage.The breeding season is in the first half of the year and probably again in August-September. The nest is described as a shallow saucer of grass, roots and twigs, very carelessly put together, and placed in high bushes in forest with thick undergrowth. The two or three eggs are white, with a chalky surface, and they measure about 35.8 X 27 mm.
The Red-Faced Malkoha is regularly seen at Sinharaja and few other remaining rain forests, frequents associating with feeding waves. It is also found in scattered riverine habitats in the dry zone, such as Lahugala, Wasgamuwa, Manik Ganga and Kubukkan Oya.

Description

This is a large species at 46 cm with a long graduated tail. Its back is dark green, and the uppertail is green edged with white. The belly and undertail are white, the latter being barred black. The crown and throat are black, and the lower face white. There is a large red patch around the eye and the bill is green. Sexes are similar, but juveniles are much duller.The red-faced malkoha takes a variety of insects including caterpillars, giant stick insects, mantises and small vertebrates such as lizard. It occasionally may eat berries but this needs confirmation.Unlike most cuckoos, this is a quiet species, making only the odd soft grunt.

Size of a House Sparrow. Sexes alike, but the female is duller, coloured than the male, and has only a trace of pale-blue throat-patch; young birds have the head all green, but otherwise resemble their parents. It is strictly arboreal, never descending to the ground. Although often solitary, companions are never far away, and it keeps them informed of its movements by constantly uttering, while o the wing, a sharp three-syllabled whistle twiwittwit...twitwitwit. The lorikeet is a convivial little bird, delighting in juicy fruits, the nectar of flowers, and the juice of palms collected in toddy-drawers' pots.The lorikeet breeds in the first half of the year, and sometimes again in July-September. Its breeding habits are highly remarkable. The eggs are white and nearly spherical, measuring about 19.3 X 16 mm.
This brilliantly-coloured little parrot is found everywhere in the hills up to 4,000 feet, and in the north-east monsoon it ascends a thousand feet higher; it also inhabits the low-country wet zone and parts of the dry zone to the south of the Northern Province.

About the size of the domestic pigeon, but with a long tail. Sexes alike. Young birds are duller, and have only a trace of he black and white 'chess board' patch on the side of the neck.Exclusively a forest dweller, It lives in pairs though small flocks will form where food is abundant. It is strictly arboreal, feeding on a variety of small jungle fruits and berries, among which the fruits of the wild cinnamon are much liked.The breeding season is from February to May, and again from August to October. The nest is the usual pigeon-type, scanty platform of twigs; it is placed among foliage and twiggery in the canopy of a forest tree, or in the top of a tall sapling, usually at height of fifteen to twenty feet. The single, white egg measures about 38.5 X 28.2 mm.

This handsome pigeon is confined to the hill forest of Sri Lanka, though it has a close relation (the Nilgiri Wood Pigeon), of very similar appearance and habits, in the hills of South India. It s normal range is from 3,000 feet upwards to the highest elevations, but it wanders about a great deal and sometimes descends as low as 1000 feet in the damp forests of the wet zone.

This species nests in damp evergeen woodlands in the central highlands, building a stick nest in a tree and laying a single white egg. Its flight is quick, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. Most of its food is vegetable. Normally silent it utters an owl-like hoo call in the breeding season.The Sri Lanka wood pigeon is 36 cm in length. Its upperparts and tail are dark grey, and the head and underparts are lilac, becoming paler on the belly. There is a black-and-white chessboard pattern on the nape.

Slightly smaller than the Common Coucal, from which it may at once be distinguished by its leg, like-green beak; its wings, too, are much darker chestnut, and the sheen on the head and neck is purple, not blue. Sexes alike.A very shy and elusive bird, it is far better known by its calls than by sight but, wherever the wet-zone forests have been spared the axe, it is still fairly common its range, however, is rapidly dwindling and as it shows no sign of being able to adjust itself to new conditions, there can be no doubt that its days will soon be numbered - with those of several ither endemic forest birds - unless wise foresight reserves extensive forest sanctuaries in the wet zone.

This coucal is found only in the forests of the wet zone, west, south-west and south of the main mountain massif, which it ascends to 2,500 feet, or perhaps higher.
