Definition
Lawes's parotia (Parotia lawesii) is a species of bird-of-paradise in the family Paradisaeidae, endemic to the highland forests of eastern New Guinea.
Overview
This medium-sized passerine inhabits montane and sub‑montane rainforest at elevations of roughly 1,500–2,500 m. The species is best known for the male’s elaborate ornamental plumage and complex courtship dances, which have been extensively documented in field studies of avian sexual selection. The female is cryptically coloured, providing camouflage while nesting.
Etymology / Origin
The specific epithet lawesii honours William George Lawes (1839–1907), a British missionary and linguist who worked in New Guinea. The name was formally applied by the English zoologist George Robert Gray when the species was described in 1858.
Characteristics
- Size: Adults measure about 28 cm (11 in) in length.
- Male plumage: Predominantly black with iridescent bronze and greenish highlights. The head displays a spectacular arrangement of six elongated, wire‑like occipital plumes that can be fanned outward. The breast and flank feathers form a glossy, metallic “cape” used in display.
- Female plumage: Brownish‑olive upperparts with paler underparts; lacks the ornamental head plumes.
- Behavior: Males perform a “ballerina” display on cleared forest patches, leaping, hopping, and spreading their breast feathers while shaking the head wires to produce a shimmering visual effect. Vocalizations during display consist of soft, rhythmic clicks and whistles.
- Diet: Primarily frugivorous, supplementing with insects and other arthropods captured on the wing or gleaned from foliage.
- Reproduction: The species is polygynous; females construct cup nests on low branches, lay a single egg, and provide all parental care.
- Conservation status: Assessed as Least Concern by the IUCN, though habitat loss from logging and mining creates localized pressures.
