The clutch contains 1, maybe occasionally 2 eggs; the few eggs that have been studied were about 33 x 24 mm in size, but these were possibly small specimens. The male is a velvet black bird with an erectile silvery white forehead crest, iridescent purple blue nape and golden green breast plumes which are structurally colored. The breast plumes have V-shaped barbules, creating thin-film microstructures that strongly reflect two different colors, bright blue-green and orange-yellow. When the bird moves the color switches sharply between these two colors, rather than drifting iridescently. During courtship, the male bird systematically makes small movements to attract females, so the structures must have evolved through sexual selection.

The iris is colored in various amounts of blue and yellow, changing according to the bird’s mood. The male attends a terrestrial court where it shows a complex display courtship involving a dance. However, some females return to the same male each year.

Lawes’s parotia, is a medium-sized passerine of the bird-of-paradise family, Paradisaeidae. Occasionally, the eastern parotia is considered a subspecies of P. lawesii. The few eggs that have been studied were about 33 x 24 mm in size, but these were possibly small specimens. The bird’s home was discovered by Carl Hunstein on a mountain near Port Moresby in 1884.

List of species seen in Wild KrattsThe Lawes’s Parotia, is a medium-sized passerine of the bird-of-paradise family, Paradisaeidae. It is distributed and endemic to mountain forests of southeast and eastern Papua New Guinea. Occasionally, the eastern parotia is considered a subspecies ofP. The species is similar to the western parotia . Like most birds of paradise, male Lawes’s parotia are polygamous.

Polygamy is the practice of breeding with multiple partners. When a male breeds with more than one female at the same time – it is called polygyny…. Wikispecies has information related to Parotia lawesii. This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author’s life plus 100 years or fewer. Some lists regard Eastern Parotia as subspecies of this species. Endemic to the highlands of east-central New Guinea to the southern slopes of the southeast peninsula.
The Lawes’s Parotia is a polygamous bird, as males display to attract as many females as possible. The male carefully clears the land to use it as an area for courtship rituals. During the mating ritual, the male moves his head and loosens the feathers on his chest and sides, following predetermined movements to show the metallic reflections of his chest and nape. After mating, the females build their own nests, incubate eggs and care for their offspring. Adorned with three ornamental spatule head wires from behind of each eye and elongated black flank feathers, that spread skirt-like in courtship display. The female is a brown bird with dark head, yellow iris and dark-barred yellowish brown below.
