Principe Sunbird

A small bird of mid-montane forest. Fairly thick-bill, yellowish-tinged underparts, yellow tufts on the sides and a long tail with white outer edge. Female is dark olive above and paler below. Male is black above and grayish below. Similar to other berrypeckers but longer-tailed and shorter billed than Black, lacks the orange in the bill of Obscure and shorter-tailed than Fan-tailed. Voice, a high-pitch, jumbled, twittering song and a thin, whispy call.

Large, dark brown skua with a very robust beak. Several subspecies vary in plumage from largely dark to mottled pale brown. In flight, exhibits a broad white patch on both upperwings and underwings. Usually seen well offshore, less often towards the coast; often follows boats. Lacks the capped appearance of Great and Chilean Skuas, and has darker underwing coverts than those species. The dark morph of South Polar Skua has colder tones and a smaller bill, but field separation is difficult.

A small bird of mid-montane grasslands in western New Guinea. Black face and chest, brown upperparts, yellow rump and tail, yellow sides and white belly bordered with a black line, and a thick, silver-blue bill. Usually seen in small flocks. May have a slight altitudinal overlap with Snow Mountain, but Black-breasted Munia is normally lower and has a black chest. Call, a squealing “week!” repeated constantly.
