Cabanis's Ground-Sparrow
Melozone cabanisi
Rather local large sparrow of foothills and highlands in central Costa Rica. Found in brushy woodland and edge and overgrown clearings; usually on or near the ground and often in pairs. Like other ground-sparrows, spends most of its time skulking in shady and often dense cover. Large black spot in middle of chest. Head pattern is distinctive: rusty cap, black forehead and cheek wrapping around a white face with a beady dark eye.
识别特征
It is on average 15 cm long and weighs 28 g. The adult has a stubby dark-grey bill, unstreaked olive-brown upperparts, a rufous crown and mainly white underparts. Young birds are browner above, have yellower underparts, and a duller indistinct head pattern. The rufous of the crown extends to behind the eye and is bordered on its anterior edge with black. This black border is broken by a white eye ring. The forehead is white, bordered below with a thin black line; there is a black malar stripe, and a black central breast patch.

Black-necklaced Scimitar-Babbler
Erythrogenys erythrocnemis
Medium-sized, strikingly patterned songbird endemic to Taiwan, where less common than Taiwan Scimitar-Babbler. Brown above, white below, with rich olive-brown flanks, rusty undertail coverts, and black “necklace” of blobby black streaks. Inhabits foothill and montane forests, where it skulks in undergrowth and shrubby edge. Pairs duet, giving bouncy-sounding hoots; alarm calls harsh and grating.
Yellow-whiskered Greenbul
Eurillas latirostris
Medium-sized, dark olive-green greenbul with distinctive yellow stripes on the sides of the throat. Found in rainforest, montane forest, gallery forest, secondary scrub, overgrown cultivation, and gardens. Generally common, but retiring and usually detected by voice. The vocalizations consist of low “chrow” notes, which are given endlessly in a chatty series throughout the day. Separated from other greenbuls by its yellow whiskers.
Blue-gray Tanager
Thraupis episcopus
Common and widespread powder blue-gray bird of open and semi-open areas with larger trees and hedges, towns, villages, and gardens in tropical and subtropical regions. Mainly feeds at mid-upper levels in trees, eating fruit, and perches readily on phone wires. Rather plain but distinctive appearance, with beady dark eye and fairly stout bill. Populations east of the Andes in South America have broad white wing-bars and look very different.
