Black-capped Tinamou
Crypturellus atrocapillus
Subtly colorful tinamou of dense habitats in the lowlands and Andean foothills. Almost exclusively found in bamboo thickets, but also occasionally found in dense riverside vegetation and secondary growth, including around agriculture. Rarely seen, but frequently heard throughout the day; it usually gives about one call note per minute, a springy “bwow”. The most helpful visual field mark is its bright orange legs; it also has a black or dark gray cap, and brown plumage with cold gray head and neck, and reddish orange throat.
识别特征
The black-capped tinamou is approximately 28 to 30 cm (11–12 in) in length. Its upper-parts are brown, mottled and barred blackish, throat and neck are rufescent, breast is dark grey, and the remainder of underparts are cinnamon to buff. Its cap is blackish and legs could be pale red or bright red. The females are more heavily barred above.
分类信息
All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.<p>The black-capped tinamou has two subspecies as follows:

行为
Like other tinamous, the black-capped eats fruit off the ground or low-lying bushes. They also eat small amounts of invertebrates, flower buds, tender leaves, seeds, and roots. The male incubates the eggs which may come from as many as 4 different females, and then will raise them until they are ready to be on their own, usually 2–3 weeks. The nest is located on the ground in dense brush or between raised root buttresses.
保护状况
It has an estimated global extent of occurrence of 120,000 km2 (46,000 sq mi). It is rated as least concern status by the IUCN

New Caledonian Imperial-Pigeon
Ducula goliath
Enormous, long-tailed, mostly dark slaty-blue pigeon with dark rufous belly and vent. Tail dark chestnut at the base and dark gray towards the tip. Found throughout New Caledonia, preferring hilly or montane forest and most common in areas with high-quality habitat. Larger than any other pigeon or dove species on New Caledonia. Listen for its far-carrying low-pitched booming song, especially early in the morning.
Hodgson's Treecreeper
Certhia hodgsoni
Beer-bellied tree-climber with intricately patterned brown upperparts, white underparts, and a decurved bill. Combination of rusty rump, unstriped brown tail, and clean underparts distinguish this species from other similar treecreepers in its range. All but identical to Eurasian Treecreeper, but no range overlap; confined to the Himalayas and Central China. Favors conifers but can also be found in mixed and broadleaf forests. Song begins with a few high thin notes and devolves into a buzzy twitter.
Bokmakierie
Telophorus zeylonus
A large, sturdy olive-gray and yellow bushshrike with a distinctive black chest band that arcs up to the bill base, forming a broad necklace. In flight the dark tail has striking yellow tips. The juvenile is dull and lacks the chest band. Pairs are bold in shrubby and open country, where they forage low in bushes or grass clumps, hopping on open ground or running between clumps looking for invertebrates. The species has a varied and complex repertoire of songs and calls, the most characteristic of which is a duetted onomatopoeic “bok-mak-ie-rie,” often delivered from a conspicuous perch.
