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.
识别特征
This is a small bird, 12.5 cm (4.9 in) long, of fairly drab appearance. It is brownish with lighter and darker streaks above, and off-white below and on the supercilium. It is browner above than the common treecreeper (C. familiaris), with a contrasting rufous rump. It has a long curved bill and long stiff tail feathers.<p>The song starts with two of the shree calls characteristic for this species and its close relatives. Then follow one or a few warbling calls, and finally (usually) two up- and downslurring notes. Each sound is about 0.3 seconds long, and the whole song takes about 2 to 2.5 seconds. It drops in pitch at a constant rate from around 7.5 kHz initially to 6 kHz, slurring down to 4 kHz once or twice in the end.
分类信息
It has three subspecies, from west to east:<p>This treecreeper was formerly included in the common treecreeper (C. familiaris), but is now believed to constitute a distinct species. It is the southeastern representative of the Holarctic lineage of treecreepers, most closely related to its sister species C. familiaris and to the North Atlantic superspecies short-toed treecreeper (C. brachydactylata) and American treecreeper (C. americana).<p>Though the Certhiidae are very diverse in the Himalayan region, the other species found there belong to a lineage distinct from Hodgson's treecreeper. While the present species is an allopatric offshoot of the Holarctic group, the other Himalayan treecreepers are parapatric members of a group that probably radiated out from the subtropical southern China region.<p>The English and scientific names of this species commemorate Brian Houghton Hodgson, a 19th-century English naturalist and ethnologist working in British India.

Collared Lark
Amirafra collaris
An elegant lark with rich rusty upperparts and white feather fringes that create a scaly effect. The complete dark band across the chest and the dark streaking on the nape are unique; the white eyebrow and throat create a bold face pattern. Underparts are pale and clean. Resident in dry thorn savanna on red sands. Its long whistle “wheeeeooooo” is sometimes accompanied with a wing-clapping display in which the bird rises 10–15 meters before parachuting back to the ground. Foxy Lark is similar to Collared in shape and coloration but lacks the dark breast and neck markings.
Numfor Leaf Warbler
Phylloscopus maforensis
A small dull-colored warbler with an indistinct pale eyebrow, a dull greenish upperside, a pale throat, and dull yellowish underparts. Usually shows an indistinct wingbar. Singles, pairs, and small groups inhabit lowland and hill forest, including secondary forest. Often joins mixed-species flocks. Sings a variable high-pitched warble mixed with twittering phrases. Easily identified as the only warbler in its limited range. Separated from other small yellowish birds such as flowerpeckers and sunbirds by the shape of the bill.
Jabiru
Jabiru mycteria
Huge, massive-billed, and unmistakable stork of tropical lowlands. Found in marshes and flooded fields, but nests high in large trees. Sometimes seen feeding in wetlands in loose association with other wading birds, which are all much smaller. Flies strongly and often high overhead, sometimes even soaring like a vulture. Plumage is wholly white (no black in wings in flight) but the naked head and neck are black, with a broad red band at base of the neck.
