Striated Softtail
Thripophaga macroura
Distinctive-looking rufous bird, heavily streaked with a bright cinnamon tail. Note the orange chin patch. Found in humid forest with dense vine tangles, where it forages by gleaning from the understory to the subcanopy and often accompanies mixed-species flocks. The song is two clear notes flowed by a rattle. The superficially similar but larger Pale-browed Treehunter lacks the orange chin and has a more robust bill.
识别特征
The striated softtail is 17 to 18 cm (6.7 to 7.1 in) long. The sexes have the same plumage. Adults have a buff supercilium and pale lores on a otherwise buff-streaked brown face. Their crown, back, rump, and uppertail coverts are dark reddish brown streaked with black-edged reddish-rufous to rufous-buff. Their tail is pale tawny to cinnamon-rufous. Their wings are mostly dark rufous with dusky tips on the flight feathers. Their chin and upper throat are orange-rufous to yellowish orange. The rest of their underparts are dull brown with buff streaks that fade on the belly and undertail coverts. Their iris is deep chestnut brown, their maxilla dusky horn to silvery gray, their mandible bluish gray with a dusky horn tip, and their legs and feet dull greenish gray. Juveniles have a dull brown chin and throat, less well-defined streaks on the back than adults, and mottled rather than streaked underparts.

Eastern Cattle-Egret
Ardea coromanda
Small, compact white heron with relatively short yellow bill. More often seen in dry habitats than other egrets, but also frequent in rice paddies and shallow wetlands. In the breeding season, look for bright orange head and breast, as well as a brighter bill. Leg color varies from reddish or yellow during the breeding season to black during the nonbreeding season. Juveniles have dark bill. Always note relatively short, thick neck and short legs compared with other egrets. Often gathers in flocks, frequently following large animals and field machinery.
Dusky Lark
Pinarocorys nigricans
A robust, elongated thrush-like lark with dark, lightly scaled upperparts, heavily streaked pale underparts, and a boldly marked face. Pairs breed (July-October) in open broadleaf woodland, often in recently burned areas. Small post-breeding flocks disperse south and occupy suitable habitat in an unpredictable manner, sometimes irrupting. Pairs or loose flocks walk on the ground foraging for insects and seeds, flicking their wings. The Groundscraper Thrush differs by being larger and having a plain (not scaled) back.
Western Spindalis
Spindalis zena
Uncommon in thickets, forest edge, and gardens, where found mainly at fruiting trees and bushes. Usually in pairs or small flocks, and often quite inconspicuous. Handsome male is unmistakable, with bold head pattern, golden-yellow and dark reddish body plumage, and bold white wing pattern. Female is notably drab, grayish olive overall with a small white mark on the wing, and a ghosting of the male wing pattern.
