Rufous-headed Robin
Larvivora ruficeps
A shy ground-dwelling songbird with a highly restricted range. Male is unmistakable, with a bright rusty-orange hood and a white throat thickly bordered in black. Its tail is also rusty and black, but this is often difficult to see; listen for its melodic and surprisingly powerful warbling song, reminiscent of a thrush’s. The female is brown overall without any key distinguishing characteristics. Darker face and no traces of blue anywhere on the body help distinguish it from similar Siberian Blue Robin. Breeds in subalpine forests with a dense understory in a small area of central China. Very rare and possibly nearing extinction.
识别特征
This is a small robin (average length 15 cm) with orange-rufous head, a black face, and a white throat with black bordering. Back, upper breast and flanks are grey, most of the belly and underparts are white. The tail is black with rufous fringes and blackish tips to outer feathers. The song is powerful and clearly phrased, and most similar to that of the Ryukyu robin.
分类信息
The rufous-headed robin was previously placed in the genus Luscinia. A molecular phylogenetic study published in 2010 found that Luscinia was not monophyletic. The genus was therefore split and several species including rufous-headed robin were moved to the reinstated genus Larvivora.<p>Within the genus Larvivora the rufous-headed robin is genetically most closely related to the rufous-tailed robin (Larvivora sibilans). These two species form a sister group to a clade comprising the Japanese robin (Larvivora akahige) and the Ryukyu robin (Larvivora komadori).

分布与栖息地
The species has been recorded from only seven confirmed or probable breeding sites in the Qin Mountains of Sichuan and southern Shaanxi, and is also known from a very few scattered migrant records. While good population estimates are absent, it is assumed to have a very localized distribution and small total population size of no more than 1,500-3,800 individuals.<p>It inhabits mixed coniferous and deciduous forest and scrubland in a very narrow altitude band (2,400-2,800 m above sea level), apparently making use of successional scrub in valley bottom areas subject to flash-floods.<p>Using known breeding records of the rufous-headed robin, ecological niche modeling predicts that there should be suitable habitats for this species in north and central Sichuan, south Gansu, south Shaanxi and south-east Tibet.

保护状况
Populations of the rufous-headed robin appear to be on the decline. The species was classified by the IUCN as Vulnerable until 2012 and was uplisted to Endangered in 2013, based on the rarity of recent sightings, which is taken to indicate an ongoing population decline. The main threats are believed to be habitat loss and degradation, likely exacerbated to an unknown degree by capture of live specimens for the caged bird trade.

Pinnated Bittern
Botaurus pinnatus
Cryptic heron of freshwater marshes in tropical lowlands. Usually in areas with tall grasses or rushes, rarely in open situations. When alarmed, often freezes motionless with neck upstretched. The neck is finely barred horizontally, but the body plumage is vertically streaked (not horizontally barred and banded, as on immature tiger-herons). Compare with immature night-herons, which have streaked, not finely barred necks.
Eastern Bluebird
Sialia sialis
Adult males are striking royal blue above with bright orange throat and breast and bright white belly. Females are paler overall; grayish with orange on breast and sides of neck, and white belly. Favors fields and open woods. Often in small groups. Frequently perches on wires or fence posts. Nests in cavities. Listen for its soft, chortling calls.
Lewin's Honeyeater
Meliphaga lewinii
A medium-sized olive-gray honeyeater with a pale yellow cheek patch and a relatively stout bill. Cheek patch is often a crescent compared to the circular patch on Graceful Honeyeater and the oval path on Yellow-spotted Honeyeater. Adults have a bluish eye, while the similar Graceful Honeyeater has a blue-gray eye and Yellow-spotted Honeyeater has a brown eye. Listen for the rapid staccato machine-gun call of Lewin’s compared to the loud repeated whistles of the Yellow-spotted Honeyeater and the more simple, single note call of Graceful Honeyeater. Of the three easily confusable species, this is the only one found away from the tropics; it occurs in wetter forests and gardens all along the eastern coast of Australia.
