The Norfolk Pacific robin (Petroica multicolor multicolor), also known as the Norfolk Island scarlet robin or Norfolk Island robin, is a small bird in the Australasian robin family, Petroicidae. It is the nominate subspecies of the Pacific robin (Petroica multicolor) that is endemic to Norfolk Island, an Australian territory in the Tasman Sea, between Australia and New Zealand.
Taxonomy
The Pacific robin used to be considered conspecific with the scarlet robin (Petroica boodang) of Australia, but was separated in 1999, with the Norfolk Island form part of the Pacific robin assemblage.[1]
Description
The Norfolk Pacific robin is similar to many other subspecies of the Pacific robin, as well as to the scarlet robin. The adult male is distinctive, the upperparts being mainly black with a large white spot on the forehead, white bars on the wings and vestigial white tips to the tail. Its breast and upper belly are bright red with the lower belly white. The female is much duller in colouration, being mainly brown with a pinkish breast. Immatures are similar to females. It is the largest of the Pacific robin subspecies, though slightly smaller than the Scarlet Robin.[1]
Distribution and habitat
The robin is restricted to Norfolk Island, where it is largely confined to the Mt Pitt section of the Norfolk Island National Park and remnant patches of forest nearby. It mainly inhabits the native subtropical rainforest, with lower densities in other wooded habitats. It prefers areas with a dense understorey and an open ground layer with deep, moist litter for foraging in.[2]
Behaviour
Feeding
The robin feeds on a wide variety of invertebrates.[3]
Status and conservation
After a period of decline to the 1980s, when the birds disappeared from many parts of the island, the population of the Norfolk Pacific robin apparently stabilised and was estimated at 400-500 pairs in 1988 with little change in 1997. Ongoing threats include habitat degradation and predation by black rats and feral cats. It is considered Vulnerable because of the restricted size of the population and area of its distribution.[4] Ongoing conservation management actions include control of rats and feral cats to minimise predation as well as control of invasive weeds to minimise habitat degradation. It is proposed to reintroduce the robin to nearby Phillip Island when the regenerating habitat there is suitable.[5]
