Brown-necked Raven

Poorly-known and seldom-seen thrush endemic to Bougainville, in the northwestern Solomons, where it inhabits montane forests. Dark overall, with orange bill, eyering, legs, and feet. Behavior poorly-known, but like other Island-Thrushes, likely forages at all levels of forest, especially on the ground. Vocalizations are poorly understood.

A long-tailed bird of montane forest. Black back and white base to the upper tail, more extensive in the male. Male has iridescent blue-green underparts, head and bib with rufous breast band and thin, rufous stripe down the side of the neck. Female has a black head and a barred belly. Feeds on fruit and searches for insects on mossy branches and epiphytes. Range of Ribbon-tailed Astrapia may just meet, but Splendid Astrapia female has white in the base of the upper tail. Call, a clicking sound.

The only crested tit in most of its range. Black front with yellow cheek and yellow eyebrow. Yellowish-green upperparts, white-spotted wings, and yellow-and-black underparts. Females and juveniles are duller, with shorter crests, central stripe thinner and incomplete, and yellowish parts becoming dull white. A bird of the hills, it is most abundant between 500 meters and 1800 meters of elevation, but rarely descends to lower elevations. Seen in pairs or family groups, often joining mixed-species foraging flocks in the non-breeding season. Forages in the canopy, emitting loud whistles and harsh chatters.
