Vanikoro Flycatcher
Myiagra vanikorensis
A small flycatcher. Male is deep glossy blue-black on the back, hood, and tail. Chest and belly are ochre red. Female resembles male but is paler and lacks the dark throat. Found in most habitats up to 1100 meters of elevation, preferring forest edge and open woodland. Song is an excited “chwee chwee.” Call is a short harsh scolding chatter.
识别特征
The Vanikoro flycatcher is a small passerine, 13 cm long and weighing around 13 g. It has a large, slightly hooked black bill and black legs. The plumage varies between the sexes; the male has dark blue-black plumage over the head and throat, back, tail and wings, and a washed out red belly with a white rump. The pattern for the female is similar, but paler overall (orange instead of red, slate grey instead of dark blue) and with the orange of the belly also coming up the throat as far as the bill. There is some variation based on subspecies; the female of the race dorsalis of the northern Lau Group has a white throat, whereas the male of kandavensis has much richer orange underparts. The juvenile birds resemble females but also have white scalloping on the wings.
分类信息
The Vanikoro flycatcher was described by the French zoologists Jean Quoy and Joseph Gaimard in 1832 from a specimen collected on the island of Vanikoro in the Solomon Islands. They coined the binomial name, Platyrhynshos vanikorensis. It is closely related to the insular Melanesian flycatcher, Samoan flycatcher, Makira flycatcher and Solomon flycatcher, as well as the Australian leaden flycatcher. The Vanikoro flycatcher was originally described in the genus Platyrhynchos. This species should not be confused with the similarly named Vanikoro monarch which also uses Vanikoro flycatcher as an alternate name. Alternate names for the Vanikoro flycatcher include the red-bellied flycatcher, Vanikoro broadbill, Vanikoro myiagra and Vanikoro myiagra flycatcher.<p>Five subspecies are recognized:

分布与栖息地
The Vanikoro flycatcher is capable of living in a wide variety of habitats. It naturally occurs in forest and forest edge habitats from sea level up to 1100 m, but has also adapted to living in disturbed human altered habitats, including gardens and cultivated areas, so long as a few trees survive. The species is insectivorous, taking a variety of insects by sallying from perches and snatching them in the air or from the undersides of leaves. In addition to insects Vanikoro flycatchers will also eat lizards and small fruits. Individuals, pairs or even small groups forage in the canopy in undisturbed forest but will use other areas in disturbed areas; they will forage around buildings are highly inquisitive.

行为
In Fiji the Vanikoro flycatcher breeds from September to February. The nest is a small cup of plant fibres, grass stems and roots, decorated on the outside with lichen and leaves and lined with animal hair. The nest is placed high in a tree on a horizontal branch. nest construction is undertaken by both sexes, as in incubation and chick rearing. The clutch of pinkish-white freckled eggs usually numbers 1–2. Predators, like the Fiji goshawk and the local race of the peregrine falcon, are aggressively mobbed.

Blue-throated Bee-eater
Merops viridis
A bright green insect hunter with a long bill and triangular starling-like wings. Adult has a bright blue throat, orange-brown crown and nape, and long trailing central tail feathers. Sexes are alike. Juveniles have a paler blue throat, no orange-brown coloration, and no long tail extensions. Often hunts from exposed perches such as telephone lines or snags, on which it rubs its venomous quarry so as to disarm it. Call is a bright, inflected “chileep.”
Helmeted Woodpecker
Celeus galeatus
Fairly large woodpecker. A usually rare inhabitant of extensive humid forests. Note cinnamon face, red head with a prominent crest, and white stripes on the side of the neck. Solid black back and wings, and heavily barred below with a pale rump. Males have a red moustache. A mimic of the much larger Robust Woodpecker.
White-headed Sawwing
Psalidoprocne albiceps
A small, fork-tailed, sooty-brown swallow with different plumages for the sexes: distinctive male has a pure white head and narrow black eye stripe; female has a mostly ashy head with white throat. Immature lacks white on the head. Pairs use clearings and edges of evergreen forest, open woodland, and cultivation. Resident in East Africa, but an intra-African breeding migrant in Zambia and Malawi between October and May. Superficially more similar to swifts than other swallows. Note the differences in flight style: flightier with deep wing beats and rapid changes of direction, as opposed to the more stiff-winged flight of swifts.
