Black-sided robin:

The black-sided robin (Poecilodryas hypoleuca), also known as the pied robin, is a species of bird in the family Petroicidae. It is found in Indonesia and Papua New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.

The genus name is derived from the Ancient Greek words poikilos "little" and dryas "dryad", and the species name hypoleuca is derived from the Ancient Greek words hypo- "under" and leukos "white". Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens, honeyeaters and crows.[2] However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds) within the songbird lineage.[3]

Measuring 13 to 15 cm (5–6 in), the black-sided robin has black and white plumage. The upperparts including the crown, nape, back, wings and tail are black or brownish-black, as is its eye-stripe. It has white eyebrows, throat and underparts and a white patch on the wings. The bill is black, and the eyes are dark brown, and the legs grey or pink.[4]

The black-sided robin is found across New Guinea from the Huon Peninsula west to the western limits of West Papua and West Papuan Islands, although is absent from the transfly region in the south. It inhabits predominantly lowland rainforests and swamp forests from sea level to 1200 m (4000 ft). Within the rainforest it is found singly or in pairs in the understory or on the ground. Shy, it is more often heard than seen. It is insectivorous, and hunts by gleaning and snatching insects from tree trunks and branches, and on the ground.[4]

Justification

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Nominate race has white supercilium from bill to behind eye, white patch beneath eye; crown, side of head and upperparts black; upperwing and tail black, remiges with broad white patch near bases (forming bar on folded wing, prominent stripe in flight); while below, black patch on side of breast; iris dark brown; bill black; legs grey. Sexes alike. Juvenile is plain brown on crown and back, darker brown on chin, breast and flanks, and white on abdomen and undertail- coverts; immature as adult, but retains juvenile wing- coverts. Races differ minimally: steini is browner above than nominate; hermani has upperparts blacker, and white supraloral and wing patch larger.
