Doria's Hawk
Megatriorchis doriae
A large, inconspicuous raptor of lowlands and foothill forest interior. Brown back and long tail with strong barring, pale underparts with strong sparse streaking, pale eye-brow and a thick dark eye-stripe. Ambushes birds from a perched position. Has been known to take bird-of-paradise at lek sites. Similar to Long-tailed Honey-buzzard, but Doria’s Goshawk doesn’t soar, is slightly larger with a dark eye and yellow rather than white legs. Call, a short, slow series of strong, shreaking calls.

分布与栖息地
Doria's goshawk is endemic to lowland rainforests of New Guinea and Batanta Island. This bird is rarely seen and there is little record of it because the bird is not easily noticed and does not draw attention to itself. This is partly because of its camouflage and its other habits. After being monitored for seven years observation at Tabubil, Western Province of Papua New Guinea, there was only one sighting of the bird. The bird’s habitat is more specifically the New Guinea lowlands, as well as shrubs or trees that grow mainly in coastal saline or brackish water, seasonal tropical forests. Its habit is to be below forest cover or shade. The bird does not fly or rise high in the air. The bird's habitat has been decreasing as deforestation continues.

保护状况
Due to ongoing habitat loss, Doria's goshawk is evaluated as Near Threatened on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES. The conservation status of this species is that it is close to meeting the requirements for a threatened category in the future. The habitat of Doria’s goshawk was destroyed, which has a direct impact on its small and declining population. >

Fraser's Sunbird
Deleornis fraseri
A sunbird masquerading as a warbler, this medium-sized sunbird of forest and forest edge is often found in small groups or mixed-species flocks searching the understory deliberately for insects. Overall yellow-green with more olive tones to the head. Has distinctive pale spectacles around its eye and a large, slightly decurved bill. Could be confused with longbills, but note Fraser’s Sunbird’s decurved bill and noticeable spectacles around the eyes. Calls include a short, dry “tiktiktik!” The song is a longer set of sunbird-like notes with noticeable pauses in between, varying in quality from clear whistles to trills: “dree, djier, drtil, drtil.”
Crimson-crested Woodpecker
Campephilus melanoleucos
Large red-headed woodpecker, widespread from Panama to Paraguay. Found in lowland forest and edges, often perched conspicuously high up on a snag or large tree. More apt to be seen in open habitats compared with Red-necked Woodpecker, but significant overlap. Male is distinctive with barred underparts and almost entirely red head with a black-and-white patch on the cheek. Female distinguished from other large woodpeckers (such as Lineated) by very broad white stripe on face and white V on back. Listen for loud knocking drum as well as various chattering noises.
Malaita Cicadabird
Edolisoma tricolor
The male is a striking tricolored cicadabird: pitch black below and on the face, with a medium-gray cap and back, and a pale-gray bar on the shoulder. The tail is also black. The female is powder-gray with a paler shoulder patch. Found in forest only on the island of Malaita, in the Solomon Islands. Male is similar to Central Melanesian, but distinguished by its paler upperparts and darker underparts. Call is a rasping, upslurred “vvr-reeeoo.”
