Taxonomy

There are three recognised subspecies of ''Petroica boodang'': the nominate subspecies ''P.b.boodang'' is found in mainland southeastern Australia; ''P.b.leggii'' is found in Tasmania and Flinders Island in the Bass Strait; and ''P.b.campbelli'' occurs in southwestern Western Australia.

Description

Like the rest of the Australasian robins, the scarlet robins are stocky

. The males have black heads, backs and tails, black and white wings, a scarlet 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.

Territories are established and breeding commences before the migratory flame robin arrives in its range (where the two co-occur). 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. The

size is between one and four eggs, with three being the average. The eggs are grey, green or pale blue, and marked with brown to 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. The chicks hatch after 14 to 18 days. At first, they are brooded by the female and fed by the male; when brooding ends, they are fed by both parents. Nesting success is generally low, between 8 and 40%. Scarlet robin nests are raided by snakes, and they are victims of
