The Dollarbird – Eurystomus orientalis
The Dollarbird is the sole Australian representative of the Roller family, so named because of their rolling courtship display flight. The Dollarbird visits Australia each year to breed. Heavily built, flat-headed dark blue bird with a short bright red bill. In flight has a characteristic white circle, or ‘dollar’, on each underwing. Juvenile lacks red bill. May resemble mynas in flight, but note longer wings, larger head, and more powerful, less frantic flight. Nests in cavities; typically tree hollows. Frequently perches on power-lines or in the tops of tall dead trees.
It has mostly dark brown upperparts, washed heavily with blue-green on the back and wing coverts. The breast is brown, while the belly and undertail coverts are light, and the throat and undertail glossed with bright blue. The flight feathers of the wing and tail are dark blue. The short, thick-set bill is orange-red, tipped with black. In flight, the pale blue coin-shaped patches towards the tips of its wings, that gave the bird its name, are clearly visible. Both sexes are similar, although the female is slightly duller. Young Dollarbirds are duller than the adults and lack the bright blue gloss on the throat. The bill and feet are brownish in colour instead of red.
