Eyebrowed Thrush
Turdus obscurus
A long, slightly curving white eyebrow gives this species an elegant, sophisticated appearance. Typically keeps to cover on the ground and in mid-levels of trees but occasionally ventures into the open to feed, particularly during migration. Alert and quick to flush. Adult male has gray head, brown back, and orange belly. Females are brownish overall with more faded orange on the underparts. Breeds in eastern Siberian forests, typically in damp areas near water, or areas with dense understory. Winters in more open habitats, such as parks, but not as fond of open spaces as blackbirds. Well-spaced song phrases consist of rich warbling and ringing buzzy whistles. Also gives a high, piercing “tsssst!”

分类信息
The eyebrowed thrush was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the thrushes in the genus Turdus and coined the binomial name Turdus obscurus. The scientific name comes from Latin Turdus meaning "thrush" and obscurus meaning "dark" or "dusky". Gmelin based his account on the "Dark thrush" that had been described in 1783 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham noted that "This is Sibirian species and found in the woods beyond Lake Baikal" but did not explain the source of his information. The species is monotypic: no subspecies are recognised.

其他鸟类
Planalto Tapaculo
Scytalopus pachecoi
Small, nondescript bird that is usually very difficult to spot. Mostly dark gray with a cinnamon vent with dark bars. Females are browner. Occurs in primary forests and old second growth, including Araucaria forest with dense understory; especially fond of areas with terrestrial bromeliads. The song is a very long and monotonous repetition of a single note.
Rainbow Bee-eater
Merops ornatus
Brightly colored bee-eater with yellow face with black mask, green and blue underparts, black tail streamers. Rust-colored underwing obvious in flight. Flocks hunt flying insects; often perch in trees and powerlines. Typically rather vocal, with a repeating insect-like ‘prr-prr’ call.
Middendorff's Grasshopper Warbler
Helopsaltes ochotensis
Like most other members of its genus, this songbird can be excruciatingly difficult to see in the dense forest edge growth or wetlands it prefers. Brown with a pale supercilium and belly, faint streaking on the crown and back, and a rufous burnish to the rump and upper tail. Very similar to Pleske's and Gray's Grasshopper-Warblers but has a more contrasting brow and belly than those two and is substantially smaller than the latter. Song is dry and rattling, comprised of a series of double notes followed by longer, more mellow-sounding ones. Calls are similarly dry and short.
