About Oriolus sagittatus (Latham, 1802)
This species, commonly called the olive-backed oriole, has a non-bright colouration. It has an olive-coloured back marked with small dark streaks, and a pale chest marked with black streaks. Females have wings edged in cinnamon, and individuals of both sexes have reddish bills and reddish eyes. In contrast to the green oriole, which specialises in damp, densely vegetated habitats in tropical far northern areas, the olive-backed oriole is more adaptable in its habitat preferences. It favours more open woodland environments and tolerates drier climates, though it does not live in desert regions. Olive-backed orioles are common to very common in the northern part of their range, and are seen less often further south, but their distribution extends as far south as south-eastern South Australia. Their overall range stretches from the far north of Western Australia, across the east and south coasts to Victoria, and reaches into the south-eastern corner of South Australia. Most olive-backed orioles breed during the tropical wet season, but some individuals migrate south to breed during the southern summer.
