Cinnamon Teal
Spatula cyanoptera
Small duck with chalky-blue patches on the upperwing (visible in flight). Breeding males unmistakable with rich reddish-brown color overall. Females are buffy-brownish overall and intricately patterned. Look for rather plain face and longer, more spatulate-shaped bill than Blue-winged Teal. Widespread and fairly common throughout western North America and South America, as far south as Tierra del Fuego. Usually found in shallow wetlands or marshes, where it can occur in pairs or flocks, sometimes mixed with other species of ducks.
识别特征
The adult male has a cinnamon-red head and body with a brown back, a red eye and a dark bill. The adult female has a mottled brown body, a pale brown head, brown eyes and a grey bill and is very similar in appearance to a female blue-winged teal; however, its overall color is richer, the lores, eye line, and eye ring are less distinct. Its bill is longer and more spatulate. Male juvenile resembles a female cinnamon or blue-winged teal but their eyes are red. They are 16 in (41 cm) long, have a 22-inch (560 mm) wingspan, and weigh 14 oz (400 g). They have 2 adult molts per year and a third molt in their first year.

分布与栖息地
Their breeding habitat is marshes and ponds in western United States and extreme southwestern Canada, and are rare visitors to the east coast of the United States. Cinnamon teal generally select new mates each year. They are migratory and most winter in northern South America and the Caribbean, generally not migrating as far as the blue-winged teal. Some winter in California and southwestern Arizona. Two subspecies of cinnamon teal reside within the Andes of South America. The smaller sized S. c. cyanoptera is widespread within low elevations (<1000m) such as the coast of Peru and southern Argentina, whereas the larger size subspecies S. c. orinomus occupies elevations of 3500–4600 meters in the central Andes.

Martens's Warbler
Phylloscopus omeiensis
A bright and attractive small warbler with many virtually identical relatives. Breeds in foothill and montane forests, where it favors areas with a dense understory. Descends into lower elevations in the winter, when it often moves around with mixed flocks. Bright green above and yellow below, with a gray-and-black-striped crown and a bright yellow eyering; note intermediately strong crown patterning and distinct yellow eyering, often weak but not broken above the eye. Song is a series of lively whistles and chirps uttered in discrete bursts.
Bornean Wren-Babbler
Ptilocichla leucogrammica
Large, stout wren-babbler. Highly dependent on pristine lowland forests; populations now declining and increasingly fragmented across Borneo as that habitat is rapidly deforested. Shy, foraging quietly under dense cover and amongst fallen trunks, usually in pairs or small groups. Best detected by song, a simple but beautiful two-note series of mournful, clear whistles: “doooo-deeee.” If seen well, note whitish face, white-and-black-streaked underparts, brown back, and pot-bellied appearance.
Black-backed Puffback
Dryoscopus cubla
A small, canopy-loving black-and-white shrike with a fiery red eye. When excited, males can raise fluffy white feathers on the rump to resemble a puffball. The sexes differ, with males clean-cut and females duller and more cream-and-gray in coloration. Singles and pairs frequently join mixed-species flocks foraging agilely for insects, working the canopy of dense broadleaf woodland and riverine, lowland, and montane forest. Black-backed Puffbacks are often detected by their characteristic song: a loud click followed by a whistled wheeeoo,” the combination given repeatedly.
