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.

Principe Thrush
Turdus xanthorhynchus
A large brown thrush with pale blue-gray eyes, a bright yellow bill, and scaly underparts. The juvenile is flecked with buffy above. The only thrush on Príncipe, where it is a rare resident in lowland and mid-elevation forest between 100 and 800 meters, preferring ravines and valley floors. Song is a varied whistled medley that is mostly given at dawn and dusk, and alarm call is a typical thush-like “dzzrt.”
White-fronted Ground-Tyrant
Muscisaxicola albifrons
Largest ground-tyrant, usually identified readily by (relatively) big size and high Andean range. Usually seen as singles or pairs foraging on bogs, but also ranges into adjacent rocky puna habitats. Plumage rather plain overall with contrasting dirty whitish forehead patch; pale wing edgings create distinctive “frosty-winged” appearance in flight. Confusion only likely with smaller Ochre-naped Ground-Tyrant, on which ochre nape can be hard to see.
Montezuma Quail
Cyrtonyx montezumae
A remarkably patterned quail, uncommon and difficult to spot as it runs through open grassy woodlands in dry regions of the southwest U.S. and Mexico. Male looks like he’s are wearing a black-and-white helmet; otherwise look for bold spots and streaks covering body and wings. Female is more subtly patterned with shades of brown; look for rounded, puffy head shape. Between bursts of running, often crouches motionless and becomes nearly invisible. Rarely flies unless flushed at very close range; most often seen crossing a road or trail. Male song is a rich descending whistle with unique ethereal tone like an incoming spaceship.
