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.[citation needed]

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. >

Ruby-crowned Tanager

Blue-headed Vireo
Vireo solitarius
Attractive, colorful vireo with thick white spectacles. Note dark blue-gray head, yellowish sides, and bold white wingbars. Breeds in forested areas, typically mixed coniferous and deciduous. Migrants can be found in any wooded area, often in flocks with other small songbirds. Winters from the southeastern U.S. to Central America. Blue-headed is the brightest of the "Solitary Vireo" complex, and usually identifiable by range alone. Compare especially with Cassin's Vireo on the wintering grounds, but note Blue-headed is more colorful and contrasty. Especially look for contrast between the dark gray face and white throat. Some birds are best left unidentified. Song is sweeter and slower than other vireos in breeding range.
