Ashy-headed Laughingthrush
Argya cinereifrons
Medium-sized, rufous babbler with a gray hood, beady pale eye, buff throat patch, and blackish bill and legs. Gregarious, usually encountered within small groups low in the understory, or on the ground, in wet forests of the lowlands and foothills. Can join mixed species flocks. Mixture of gray head, black bill and legs, and paler buff underside identify it from all other babblers on Sri Lanka. Variety of untidy vocalizations given, including scratchy notes, whistles, squeals, metallic “churrs” and “chirps”, and chattering calls, all given in combination.
识别特征
The ashy-headed laughingthrush is a rangy bird, 23 centimetre (9 in) in length with a long floppy tail. It is rufous brown above and deep buff below, with a grey head and white throat. Like other babblers, these are noisy birds, and the characteristic laughing calls are often the best indication that they are present, since they are often difficult to see in their preferred habitat.
分类信息
The ashy-headed laughingthrush was formerly placed in the genus Garrulax but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Argya.

分布与栖息地
The ashy-headed laughingthrush is a resident breeding bird endemic to Sri Lanka. Its habitat is rainforest, and it is seldom seen away from deep jungle or dense bamboo thickets in the wet zone. This species, like most babblers, is not migratory, and has short rounded wings and a weak flight.<p>Although its habitat is under threat, this laughingthrush occurs in all the forests of the wet zone, and is quite common at prime sites like Kitulgala and Sinharaja. It builds its nest in a bush, concealed in dense masses of foliage. The normal clutch is three or four eggs.

行为
As with other babbler species, ashy-headed laughingthrushes frequently occur in groups of up to a dozen, and are also often found in the mixed feeding flocks typical of tropical Asian jungle. They feed mainly on insects, but also eat jungle berries.

Himalayan Cuckoo
Cuculus saturatus
Visually indistinguishable from Oriental Cuckoo. Adult male is gray above with a black-and-white-barred belly and a dark gray tail; females usually look similar, but some (known as hepatic morph birds) have cinnamon-brown upperparts with black barring throughout. Intermediate in size between Common and Lesser Cuckoos; distinguished from both species by buffy (not white) under-tail feathers and from Lesser Cuckoos by yellow iris. Song is a series of five notes, with the leading note being sharper and more distinct than the four that follow; compare with Oriental Cuckoo’s series of mellow paired notes. Breeds in a wide range of different lowland and hill forests; also more open habitats outside of breeding season.
Yellow-billed Nuthatch
Sitta solangiae
Small stunningly beautiful nuthatch of tropical and subtropical evergreen forest, typically in hilly areas and valleys. Back and wings are bright blue, and underparts are gray. Purplish face is marked by an elegant inky black eyebrow and forehead; bright yellow bill and eye ring. Roves around in small groups or pairs, sometimes joining mixed flocks, usually moving in the canopy or middle levels. Call is a dry, brisk “chit”.
Flammulated Treehunter
Thripadectes flammulatus
Uncommon medium-sized brownish bird of Andean montane forest from Venezuela through Ecuador and just barely into Peru. Distinctive among treehunters with its bold buffy streaking covering the entire head, back, and body. Rufous wings and tail. Sexes alike. Usually found singly or in pairs moving furtively through the understory of forest, often around bamboo, from around 2,200–3,500 m. Does not typically follow mixed-species flocks.
