1854 - Western Yellow Robin, Eopsaltria griseogularis
Eopsaltria griseogularis 1
The western yellow robin (Eopsaltria griseogularis) is a species of bird in the Australasian robin family, Petroicidae, native to Australia. Described by John Gould in 1838, the western yellow robin and its Australian relatives are not closely related to either the European or American robins, but they appear to be an early offshoot of the Passerida group of songbirds. Ranging between 13.5 and 15.5 cm (5+1⁄4 and 6 in) long, it has grey upperparts, and a grey breast and head, broken by whitish streaks near the bill and below the eye, with a conspicuous yellow belly. The sexes are similar in appearance. Two subspecies are recognized: subspecies griseogularis, which has a yellow rump, and subspecies rosinae with an olive-green rump.
The species inhabits open eucalypt jungle, woodland, and scrub, generally favouring habitats with significant understory. Its range comprises the Southwest of Western Australia and the state's southern coastline, as well as the Eyre Peninsula in South Australia. It breeds in a cup-shaped nest in a tree. Predominantly insectivorous, the western yellow robin pounces on prey from a low branch or forages on the ground. Although it is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species, it has declined in parts of its range.
