Indian Blue Robin
Larvivora brunnea
Male is slaty-blue with a white eyebrow, dark face, and orange underparts. Female is matte brown with buffy underparts; females in the Chin Hills have a slate-gray back. Furtive and skulky; male sings from deep cover, giving a series of sharp whistles devolving into a burst of trilling and chattering notes. Prefers dense, damp undergrowth in wet forests, often in proximity to streams and gullies.
Identification
The Indian blue robin is similar in size to the related bluethroat at 15 cm long. The adult male has blue upperparts and rufous underparts. A bright white supercilium contrasts with a black mask that continues down the neck. The lower belly and undertail are also whitish. The female is olive brown above and buff below with a light eye-ring and rufescent rump. The breast and flanks are buffy.<p>Young birds are dark brown with buff spots.
Taxonomy
The Indian blue robin was described by Hodgson who placed it in a new genus Larvivora but it was later placed in the genus Luscinia. A large-sample molecular phylogenetic study published in 2010 found that Luscinia was not monophyletic. The genus was therefore split and several species including Indian blue robin were moved to the reinstated genus Larvivora. Larvivora is a sister of the species Brachypteryx cruralis, Brachypteryx leucophrys and Brachypteryx hyperythra.

Behavior
The Indian blue robin is insectivorous and feeds mainly on the ground. It skulks in undergrowth and hops on the ground, frequently flicking and fanning its tail. The breeding season is May to July and the nest is a large cup of vegetation placed on the ground between the roots of large fir tree or in depression. The nest is lined with roots, hair and down. The usual clutch is 4 light blue eggs. Only the female is believed to incubate but both sexes take part feeding the young. The cuckoo Cuculus canorus has been recorded in old literature as a brood parasite of the species.<p>These birds arrive in the Himalayan breeding grounds in May and leave in September. Southward migration begins in August. During the migratory season they may be found as passage migrants all over peninsular India. In winter they are found mainly in the hill forests of southern India, the Western Ghats and in Sri Lanka. They arrive in mid-September and leave the winter quarters in mid-April. Males appeared to be commoner than females in a survey conducted in the Nilgiris suggesting either differences in the timing of migration of males and females or variation in wintering areas. At Point Calimere they have been regularly trapped during October and November on their return migration from Sri Lanka but rarely on the southward migration with suggestions that they may follow different routes.<p>The habitat in which they are found is usually dense and dark forest with undergrowth and leaf litter. They sing and call in their winter grounds. The song consists of a sudden and sharp series of whistles ending in a rapid series of notes. They also utter a sharp and low clicking alarm note.

Other Birds
Yellow Longbill
Macrosphenus flavicans
An unusual warbler with a long bill and yellow eyes. Brownish above and dull yellow below with a gray head and whitish throat. Found in rainforest, mainly in dense tangles at middle levels, usually in pairs or small groups. Similar in appearance to other longbills, but with a good view, separated by the coloration of the underparts. Most often detected by the distinctive song: a long series of clear whistled notes in which each note is slightly lower in pitch. The pattern is similar to that of Sabine’s Puffback, and the individual notes sound very batis-like.
New Hanover Munia
Lonchura nigerrima
A small, little-known bird of grasslands and clearings on New Hanover in the Bismarck islands. Black underparts, back and face, brown wings, yellow rump and tail, and a silver-gray bill. Probably the only munia on New Hanover Island. Usually seen in flocks. Somewhat similar to New Ireland & Buff-breasted Munia of neighbouring New Ireland, but New Hanover has a black belly. Voice, gives quiet, tinkling notes and a nasal flight call.
Evergreen-forest Warbler
Bradypterus lopezi
Mid-sized warbler with a long, spiky tail. Varies geographically, with most birds dull brown or olive-green, though there is a bright rufous subspecies around the Albertine Rift. Found in forest at middle and high elevations. Skulks in dense undergrowth; remarkably shy and elusive. The song is a series of several “chu-wit” couplets that increase in volume. Similar to Cinnamon Bracken- and Bangwa Warblers, but in most of the range distinguished by much less rufous overall coloration. Around the Albertine Rift, distinguished from Cinnamon Bracken-Warbler by the lack of a well-defined white throat.
