English: Scarlet Robin

The Scarlet Robin (Petroica boodang) is a common red-breasted Australasian robin in the passerine bird genus Petroica. The species is found on continental Australia and its offshore islands, including Tasmania. The species was split into two in 1999 by Schodde and Mason,[2] and as the original collection by Gmelin was from Norfolk Island, this retained the name of multicolor and is now known as the Pacific Robin (which is found from Norfolk Island to Samoa).

Description

Like the rest of the Australasian robins, the Scarlet Robins are stocky passerines with large heads. They range in size from 12 to 13.5 cm in length and weigh between 12 and 14 g. The plumage is sexually dimorphic. The males have black heads, backs and tails, black and white wings, a red breast and white belly, forehead and rump. The female matches the male in pattern but is duller, with brown plumage instead of black, a much more washed out red on the breast and a buff belly. Juvenile birds resemble the female without the reddish wash on the breast.[3]

Distribution, movements and habitat

The Scarlet Robin is endemic to Australia, where it is found near the coast from southern Queensland to central South Australia, Tasmania and south west Western Australia. The species is mostly sedentary over most of its range, but some mainland populations undergo small local movements in the autumn and winter, either to more open habitats or lower elevations.[3]

The Scarlet Robin is most commonly found in eucalyptus woodland and forest from sea level to 1000 m, particularly the more open habitats with grassy and shrubby understories. During the winter more open environments, including urban habitats, are frequented.[citation needed]

Behaviour

The Scarlet Robin feeds on arthropods such as insects and spiders.[3] It adjusts its foraging behaviour seasonally, feeding mostly on the ground during the winter, but during the summer and spring prey is more commonly snatched from bark and foliage.[4]

Breeding biology


The Scarlet Robin is a territorial and monogamous species, and defends its nesting territories both from others of the same species and pairs of the related Flame Robin.[5] Territories are established and breeding commences before the migratory Flame Robin arrives in its range (where the two co-occur).[5] Both the male and the female participate in selecting the nesting site, but only the female constructs the nest, a task which takes four to ten days.[6] The clutch size is between one to four eggs, with three being the average. The eggs are grey, green or pale blue, and marked with brown olive-brown splotches and spots, usually concentrated around the large end. Only the females incubate the eggs, and the males feed the females on the nest.[6] The chicks hatch after 14 to 18 days. At first they are brooded by the female and fed by the male, once brooding ends they are fed by both parents.[3] Nesting success is generally low, between 8 and 40%. Scarlet Robin nests are raided by snakes and are victims of brood parasitism by various species of cuckoo.[3]
