Radde's Warbler
Phylloscopus schwarzi
Small, chunky songbird. Brown overall with a pale throat, thick pinkish bill, and a black-bordered white supercilium that is buff-tinged in front. The smaller Dusky Warbler has brownish tinge toward the back of the brow. The similar Yellow-streaked Warbler is a grayer shade of brown, has a clean white supercilium, and has different vocalizations. Favors open taiga forest and forest edge for breeding, often in wet brushy thickets or along streams. Sings from both exposed and hidden perches, giving a ringing trill with several variations. Difficult to detect on the wintering grounds, where it skulks in dense vegetation in both wet and dry areas; listen for its frequently repeated “chuk” and “pit” calls.
识别特征
This is a warbler similar in size to a willow warbler. The adult has an unstreaked brown back and buff underparts. There is a very long prominent whitish supercilium, and the pointed bill is thicker than that of the similar dusky warbler. The legs are paler than dusky's, and the feet look large, reflecting the more terrestrial lifestyle of this warbler. The sexes are identical, as with most warblers, but young birds are yellower below. The call is a soft chick.

分布与栖息地
Radde's warbler breeds in southern parts of Central and Eastern Siberia as far east as Korea and Manchuria. It is a migratory species and spends the winter in Bangladesh, Cambodia, Laos, Myanmar and Thailand. In its breeding range, Radde's warbler is found in open deciduous woodlands with some undergrowth and bushy woodland margins, often near water. In its winter quarters it occupies the fringes of forests, thick scrub and bushy places near woodland. Like most Old World warblers, this small passerine bird is insectivorous.

White-lored Warbler
Myiothlypis conspicillata
Gray and yellow warbler found only in the Santa Marta Mountains of Colombia. Note the white crescents above and below the eye, white stripe between the eye and the bill, and the dark crown stripes. Usually encountered in pairs that stay quite low inside cloud forest. Gives a squeaky, high-pitched series of notes, and pairs often sing together. Regularly seen in El Dorado Nature Reserve, often near the lodge.
Red-legged Crake
Rallina fasciata
Small, brightly-colored crake of wet patches in dense forests; occasionally can be found in parks and edge areas with suitable habitat. Brown with an orange head and zebra-striped sides. Bright red patch of bare skin around the eye gives it a somewhat startled appearance. Candy-red (instead of dark) legs distinguish it from Slaty-legged Crake, and dainty, smaller-billed appearance distinguish it from Ruddy-breasted and Band-bellied Crakes. Generally shy and unobtrusive, moving quietly through wet vegetation. Tends to be difficult to see, but generally common and reliable in Singapore and some areas of Thailand.
Horned Curassow
Pauxi unicornis
Very distinctive and very rare curassow of the central Bolivian Andes. Note distinctive blue vertical “horn” above the orange bill. Due to small range and high hunting pressure, only known from a few remote sites in the middle elevation forest of Santa Cruz and Cochabamba departments, Bolivia. Very wary and skittish, most easily detected by low, deep calls. You are part of an exclusive club if you see one of these in the wild.
