Obi Golden-Bulbul
Hypsipetes lucasi
A thrush-sized bird with a heavy bill, olive-green upperparts, and a yellow underside. Particularly note the yellow cheeks and the yellowish patch beside the bill, making the dark eye stand out from the face. Pairs and small groups inhabit forests, edges, scrubland, and plantations. Confined to the island of Obi. Separated from female Black-chinned Whistler by unscaled throat, solid yellow underside, and yellow facial sides. Vocalizations include an inflected high-pitched whistle, “tseeooeee.” Also gives a staccato, two-note “wit-cheer” with a longer second note, plus nasal “too-too” calls.

Natal Spurfowl
Pternistis natalensis
A medium-size brownish francolin with distinctive yellow nostrils and a bright orange-red bill and legs. The back is mottled brown, and the underpart feathers are edged brown and white, giving it a marbled scaled appearance. Juveniles are similar to adults, with duller legs and bill. It is common in savanna, preferring thicker understory. The call is a loud raucous “kak-kreek” that variably accelerates and decelerates. Red-billed Francolin differs from Natal Francolin by having barred (not scaled) underparts and a yellow eye-ring. Swainson’s Francolin differs from Natal Francolin by having red facial skin and dark blackish legs.

Whitehead's Broadbill
Calyptomena whiteheadi
Magnificent emerald-green giant of a broadbill, with distinctive black mottling and streaking. Males have black streaking on the underparts which females lack. A specialty of Borneo’s central highlands, where it can be found in montane forest with extensive tall pristine growth. Typically seen singly, but occasionally also in pairs or small flocks, especially at fruiting trees. Gives a sharp metallic “tlak!”, followed by a grating rattle.

Numfor Paradise-Kingfisher
Tanysiptera carolinae
A long-tailed kingfisher of forest and gardens on Numfor Island where it is the only paradise-kingfisher. Dark blue body with deep blue crown and shoulder patch, bright red bill and long, white raquet-tail, rump and undertail. Like other paradise-kingfishers, slowly pumps its tail while perched. Song, a rising and quickly accelerating series of nasal notes, starting slowly and ending in a rapid trill “waaaaaak wak ak k-k-k-k-k-k…..”. Pairs fan and raise tail while duetting.
