Red-thighed Sparrowhawk
Tachyspiza erythropus
A small sparrowhawk of lowland forests in West and Central Africa, about the size of a large pigeon. Look for this species’ white rump and dark blackish head, back, and tail. From below, this species always has a bright white throat and variably reddish underparts that can sometimes be barred. Blunt, rounded wings and a slightly long tail give it a similar shape to the Red-chested Sparrowhawk, but note this species' small size and extremely dark upperparts.
识别特征
A very small, dove-sized sparrowhawk with a distinctive tail pattern. The red-thighed sparrowhawk is sexually dimorphic, the males of the nominate subspecies having very dark grey upperparts with a white crescent on the lower rump which is conspicuous in flight, as are three white broken tail bars on the dark grey tail. In contrast to the blackish cheeks the throat is white with the rest of the underparts pinkish white. The vermilion eye is surrounded by a red eye ring, the cere is orange red and the legs are bright orange yellow. Males of the subspecies A.e. zenkeri have deep rufous underparts and more obvious white spots on the tail. Females are much bigger than the males, with browner upperparts and a more brownish orange eye. Juveniles normally have the underparts barred with brown, sometimes up to the breast. The body length is 23–28 cm (9.1–11.0 in) and the wingspan is 40 cm (16 in).

Ouvea Parakeet
Eunymphicus uvaeensis
Spectacular, relatively large mostly green parakeet with a black face, slight bit of red on the forehead, and thin but prominent “horns” consisting of a crest made up of a pair of black feathers. Typically found in remnant patches of high-quality forest, but visits more disturbed habitat nearby, especially where fruiting trees are present. Found only on Ouvea Island off New Caledonia. Note distinctive voice: relatively low-pitched, nasal trumpeting notes, notably lower-pitched than the voice of Coconut Lorikeet.
White-tailed Tropicbird
Phaethon lepturus
A medium-sized white seabird with black marks on the wings and a yellow beak. The long white tail streamers are visible from a great distance. Nests on coastal and inland cliffs on the main islands. Often seen flying over canyons and along cliffs. At sea usually flies high above the water. Calls are loud clucks and squawks. Smaller and more graceful in flight than Red-tailed Tropicbird.
Ambon White-eye
Zosterops kuehni
A small songbird with a conspicuous white eye-ring, a green face and upperparts, a bright yellow throat, a white belly, and a yellow base to the undertail. Pairs and small groups occur in the lowlands in forest, edge, sparsely wooded areas, and gardens. Restricted to Ambon, except for a few records from Seram. Separated from Warbling and Lemon-bellied White-eyes by its white belly, and from Seram White-eye by its green face and forecrown. Song comprises a rapid, pleasant warble. Also gives penetrating “tzew” notes.
