Rufous-tailed Robin
Larvivora sibilans
Combination of strongly scaled breast, rufous tail, and round-headed appearance distinguish this species from others in its range. Small and skulky, sticking to dense shrubbery and shorter trees in its forest breeding grounds, where it favors dense, moist growth in lowland broadleaf forests. Often bolder on migration, emerging into forest edges and gardens. Song is distinctive, a long, wet-sounding descending trill.
分类信息
The rufous-tailed robin was previously placed in the genus Luscinia. A large molecular phylogenetic study published in 2010 found that Luscinia was not monophyletic. The genus was therefore split and several species including rufous-tailed robin were moved to the reinstated genus Larvivora. The rufous-tailed robin is genetically most closely related to the rufous-headed robin (Larvivora ruficeps). These two species form a sister group to a clade containing the Japanese robin (Larvivora akahige) and the Ryukyu robin (Larvivora komadori).<p>The genus name Larvivora comes from the Neo-Latin larva meaning caterpillar and -vorus meaning eating (vorace to devour), and sibilans is Latin for "whistling".

分布与栖息地
The rufous-tailed robin is a migratory insectivorous species breeding in forests in the taiga of northeastern Asia and south to Mongolia, and wintering in Southeast Asia and southern China. It is a rare vagrant to Western Europe. The first record for this bird in Europe was on Fair Isle, Scotland in October 2004. Another was seen in Poland in January 2006. More recently, it was seen in Norfolk, England in October 2011 and again in September 2013, and in Denmark in October 2012.<p>It is a bird of coniferous woodlands and damp broad-leafed woodland with fallen trees and thick undergrowth, particularly spruce and fir with willow, alder, birch, poplar and bird cherry. It is mainly a lowland species but sometimes occurs at altitudes of up to 1,200 m (4,000 ft) above sea level. In its winter quarters it is found in forests, in areas with scattered trees, scrubland, parks and gardens.

行为
This is an elusive bird and difficult to spot as it lurks among concealing branches, remaining stationary for considerable periods. It is terrestrial in its habits and insectivorous, mainly feeding on ants, beetles, spiders and other invertebrates. It often flicks its tail in a characteristic way.<p>Breeding takes place in June or July. The nest is cup-shaped and is often in a hole in a tree or on a stump and usually quite near the ground. It is made from dead leaves, grasses and moss and lined with finer materials. There are usually five or six eggs, either plain pale blue or blueish-grey irregularly blotched with brown. Migration southwards starts soon after the nestlings are reared, in late August in Russia and a few weeks later in Korea. The birds arrive in the vicinity of Hong Kong in November and also overwinter in Thailand, Laos and Vietnam. In the spring they move northwards again, reaching Korea in May and Russia by early June.

Philippine Fairy-bluebird
Irena cyanogastra
A medium-sized to fairly large bird of tall forest from the lowlands to low elevations in the mountains. Black on the face, chest, and edge to the wing, with a blackish-blue body and pale blue crown stripe, wing patch, rump, and outer tail. Note the bright red eye. Female is similar to male but slightly duller. Somewhat similar to Asian Glassy Starling or Blackish Cuckooshrike, but Philippine Fairy Bluebird has distinctive blue patterning on the upperparts. Song consists of medium-pitched whistled phrases, including distinctive “whip!” notes.
Bank Cormorant
Phalacrocorax neglectus
A medium-to-large-sized, stocky, marine cormorant that is a specialist in kelp forests of the Benguela Current, where it is scarce resident. Similar to Cape Cormorant but slightly larger and thicker-necked. Adults have a black (not orange) throat patch and honey-brown (not blue) eyes, giving them a plain-looking face. If seen well, the head is flattish with an indistinct crest that more often manifests as a bulbous forehead. In flight, it is difficult to tell from the abundant Cape Cormorant unless the characteristic white back--most prevalent in the breeding season (but absent in some individuals)--is seen. Immatures are duller but retain the adult’s characteristic shape. Best seen at roosts.
Samoan Myzomela
Myzomela nigriventris
A small, strikingly plumaged myzomela with a bright crimson-red head, chest, back, and rump and black wings, belly, and tail. Thin bill decurved. Female mostly grayish-olive with a bright red rump. Prefers forest habitats, but widespread. Unique coloration of both sexes should identify this species with certainty. Vocally shy. Common call is a high-pitched, insect-like “tseet.”
