Tumbes Sparrow
Rhynchospiza stolzmanni
Desert-loving sparrow found only in northwestern Peru and southwestern Ecuador. It has gray underparts, a brown back, a striped head, and a large bill; there is no similar species in its range. Rather solitary; usually feeds on the ground, where it can be hard to see in the low scrub it prefers. Occasionally comes up to perch on an exposed branch to sing or look around.
识别特征
The Tumbes sparrow is a medium-sized sparrow some 14.5 cm (5.7 in) long. The beak is broad and conical, with the upper mandible blackish and the lower mandible horn-coloured. The head has a grey crown with a lateral chestnut stripe that continues as far as the nape, a white superciliary stripe and a brown eyestripe. The upper parts are greyish-brown, shaded with buff, and boldly streaked with black. The wings are blackish-brown with pale edges to the feathers. The greater and median wing-coverts are blackish with chestnut edges and pale tips, and the lesser coverts are chestnut, resulting in a rather obscure barring to the wings. The angle of the wing is pale yellow. The tail is blackish-brown with pale edges to the feathers. The throat is white and the underparts are greyish-white. There is a dark moustachial stripe at the base of the beak. The song can mainly be heard in the breeding season, and consists of a repeated, clear metallic note, reiterated up to five times "chew-chew-chew-chew" interspersed with some trills.

Andaman Coucal
Centropus andamanensis
A large, pale-brown, ground-dwelling cuckoo with rusty wings and back. Skulks in bushes and low cover, where it moves clumsily as it searches for small invertebrates, small mammals, and birds to prey on. Like other coucals, it is a cuckoo that builds its own nest. Common throughout its range in gardens, groves, disturbed forests, paddyfields, etc. The song is a series of deep and resonant “hoop” notes.
Pale-eyed Blackbird
Agelasticus xanthophthalmus
Medium-sized blackbird found locally in habitats with wet grass. Shiny black, with a white or light yellow eye and sharply pointed black bill. Giant Cowbird occasionally has a pale eye and may appear similar, but is much larger than Pale-eyed Blackbird; told apart from the similar Velvet-fronted Grackle by its pale eyes, longer, more pointed bill, and shorter tail. Found in wet grasslands and grassy margins of oxbow lakes, where it forages singly, in pairs, or in small groups.
Collared Finchbill
Spizixos semitorques
An unmistakable medium-sized songbird: dark olive-green with a black head, white collar, gray “whiskers” on the face, and black-tipped tail. Namesake yellow bill is stout and slightly curved, unlike the dark thin bills of most bulbuls. Often seen perched on telephone wires, treetops, and rooftops. Forages methodically in lowland and foothill forests, gardens, and brushlands (below 1500 m). Regularly gathers in flocks, but not a common component of mixed-species flocks. Song a series of three-syllabled warbles; calls include rising “chirrup” and series of “whit” notes.
