White-capped Monarch
Monarcha richardsii
A stunning medium-sized monarch. Glossy purple-black above and on the face and chest, rusty below, with a bluish-gray bill. Conspicuous white on the head extends back into a half-collar. Mostly found in primary and secondary forest, but apparently tolerant of disturbance. Common call is a wavering, haunting, ghost-like whistle. Also gives chattering scolding notes.
识别特征
The white-capped monarch is a medium sized bird with a glossy black back, and darker black around the throat and face and a tawny belly. Its most prominent feature is its white cap on the back of its head from its nape to above its forehead, forming an eye-ring around its eye and ending in a half-collar. Juveniles look similar, but have less white on the face.
分类信息
This species was originally described as Piezorhynchus richardsii by Edward Pierson Ramsay from a specimen collected on Rendova Island. He named it in honour of Lieutenant R. N. Richards, a personal friend.

行为
Like all Monarchs, males are territorial. Studies using specimen mounts provided evidence that the strong plumage, particularly the white cap of males may serve as a social signal.

Copper Sunbird
Cinnyris cupreus
The breeding male has coppery iridescence across the head, though it looks black in poor light. Non-breeding male and female are dull and nondescript, with plain, unstreaked underparts. Found in a wide variety of open habitats, including woodland, scrub, gardens, and cultivation. Absent from thick forest. Gives a variety of vocalizations, including quick scolding calls, an accelerating series of “tip” notes, and a typical sunbird scrambled song. Identifying non-breeding male and female can be tricky, but they are smaller and plainer than most similar sunbirds.
Glacier Finch
Idiopsar speculifer
A fat and rather “neckless” finch (actually a tanager) of bogs or adjacent rocky slopes in the high Andes. Found in pairs or small groups, feeding on the ground. Note the overall blue-gray plumage with a large white crescent under the eyes; white wing patch can be hidden at rest but shows as white flash in flight. Compare with smaller White-throated Sierra Finch.
Yellow-bellied Flycatcher
Empidonax flaviventris
Small flycatcher, extremely similar to several other species. Generally shy and inconspicuous; breeds in spruce forests often near boggy areas. Migrants tend to be found in denser wet areas within woods. Olive-greenish above with distinctive yellow wash on throat and belly. Black wings with bold white wingbars. Nearly identical to Western Flycatchers, but limited range overlap. Within range, main confusion species is Least Flycatcher. Bright yellow throat and belly is usually enough to identify Yellow-bellied Flycatcher, but some worn birds can be very similar. Song is similar to Least Flycatcher ("chebek") but more slurred, with a soft buzzy tone. Not frequently repeated like Least Flycatcher. Soft whistled call note, "pwee," unlike Least's sharp "whit" call.
