Golden-naped Woodpecker
Melanerpes chrysauchen
Medium-sized woodpecker, distinctive in its limited range. Buffy below and black above, with barred black-and-white flanks. White stripe runs down center of back. Head pattern distinctive: black mask, yellow forehead, red crown, and yellow nape. Female similar but has black, not red, on crown. Most similar to Black-cheeked Woodpecker but no range overlap; also compare Hoffmann’s and Red-crowned Woodpeckers (but note Golden-naped’s solid black wings, not barred, and black mask). Found singly or in pairs, usually in forested areas and edges.
识别特征
The golden-naped woodpecker grows to a length of about 18 cm (7 in). It is similar in appearance to the beautiful woodpecker but their ranges do not overlap. The sexes are similar apart from the male having a yellow fore-crown and a red central-crown, while the whole crown of the female is yellow except for a narrow central transverse black band. Both sexes have a yellow nape, and a black mask surrounding the eyes and running to the nape. There is a small white patch behind the eye. The lores, cheeks, chin, throat and breast are pale yellow, buff or grey. The lower breast, belly and flanks are barred in black and white, and there is a red patch on mid-belly. The mantle is mainly black and the wings brownish, with the tips of the flight feathers white. The back and rump are mainly white, sometimes blotched with black, and the tail is black with white barring on the outer feathers. The iris is brown, the beak is greyish-black and the legs are greyish-olive.

Baker's Imperial-Pigeon
Ducula bakeri
A large, strikingly dark pigeon with an entirely dark upperside, a purple throat, a gray head, and a chestnut belly and underwing. Found mainly on large islands above 600 meters of elevation, but occasionally coastal. Unlike any other pigeon in Vanuatu. Most common call is a series of about 15 accelerating and shortening hoots.
White-tailed Swallow
Hirundo megaensis
A small swallow with white underparts and dark blue upperparts. The tail shows an unusual pattern: a dark rim around large white panels both above and below. Found very locally in southern Ethiopia in open thorn savanna, in areas with many large termite mounds. Often in pairs. Similar to Gray-rumped Swallow, but easily separated by the white in the tail. Could be confused with Common House Martin, but has white in the tail rather than a bold rump patch.
Striated Antbird
Drymophila devillei
Streaky long-tailed, slender antbird of bamboo forests. Black-and-white streaked, with an orange-red wash belly and lower back. Longer-tailed than similar warbling-antbirds. Found exclusively in spiny bamboo thickets, where it forages singly or in pairs in the crowns of the bamboo. Listen for its distinctive song, a series of grating notes accelerating into a rising series of whistles.
