Biak Coucal
Centropus chalybeus
A poorly known, mid-sized coucal endemic to Biak island. All black plumage, distinctive yellow iris, straightish bill and a fierce-looking face. Found in dense forest and secondary habitat at all levels and devilishly difficult to see. The only coucal species found on Biak. Vaguely similar to Torresian Crown, but Biak Coucal is more skulking with longer tail. Quite vocal and heard far more often than seen. Call, a series of deep, upDslurred “wup!” notes given at varying speeds.

Blue-breasted Fairywren
Malurus pulcherrimus
Small bird with a very long blue-gray tail held cocked, found from southwestern Western Australia to the Eyre Peninsula of South Australia, where it prefers coastal heath and drier woodland areas. Breeding male has a bright blue helmet, bluish-black breast, blue patch on back, and chestnut shoulders. Female grayish overall, with long blue-gray tail and reddish bill. Nonbreeding male resembles female but has black bill and narrow pale eyering.
White-winged Swallow
Tachycineta albiventer
Common swallow in tropical lowlands with a glossy blue-green back. Large white wing patches are easily visible in flight and on perched birds. Forked tail and gleaming white rump are also obvious in flight. Typically forages low over water. Pairs or groups frequently perch on snags in rivers and lakes.
White-breasted Parrotbill
Paradoxornis ruficeps
Chunky parrotbill with a large head and a relatively short tail. Very similar in appearance to Rufous-headed and Pale-billed Parrotbills, but note brighter coloration and whiter underparts. Forages in small flocks, often with other species, in foothill forest bamboo clusters; also in reedbeds and tall grass. Song is a descending series of 4-5 whistles: “wee-dee-dee-dee-dee.” Calls include a loud, sputtering machine-gun chatter.
