Red-capped Robin

The red-capped robin (Petroica goodenovii) is a small passerine bird native to Australia. Found in drier regions across much of the continent, it inhabits scrub and open woodland. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 10.5–12.5 cm (4.1–4.9 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive red cap and red breast, black upperparts, and a black tail with white tips. The underparts and shoulders are white. The female is an undistinguished grey-brown. This species uses a variety of songs, and males generally sing to advertise territories and attract females. Birds are encountered in pairs or small groups, but the social behaviour has been little studied. The position of the red-capped robin is unclear; it and its relatives are unrelated to European or American robins, but they appear to be an early offshoot of the songbird infraorder Passerida. The red-capped robin is a predominantly ground-feeding bird, and its prey consists of insects and spiders. Although widespread, it is uncommon in much of its range and has receded in some areas from human activity. == Taxonomy == The red-capped robin was…
