Banded Ground-Cuckoo
Neomorphus radiolosus
Impressively large, roadrunner-like bird of wet foothill rainforest. It’s one of the rarest and most sought-after birds of northwestern Ecuador and western Colombia. Note large size, long tail, chestnut back, and black-and-white scaled underparts. Terrestrial; most likely to be encountered following large swarms of army ants. Sometimes snaps its bill very loudly. Song is a series of soft, very low-pitched, rising notes given at regular intervals.
识别特征
The banded ground cuckoo is about 46 cm (18 in) long, about half of which is its tail, and weighs about 400 g (14 oz). Adults have a heavy decurved bill with a black to dusky maxilla and a grayish mandible tipped with blue-gray. Males and females have the same plumage. Adults have a black forehead and crown and a shaggy, glossy, blue-black, erectile crest. Their face is dark with bare blue skin behind the eye. Their hindneck is glossy blue-black and their upper back black with white edges giving a scaly appearance. Their lower back and rump are rich maroon-chestnut and their uppertail coverts metallic green. Their tail is black with a purple and green gloss on the upper side. Their wings have black outer primaries and purplish-red and black inner primaries and secondaries. Their underparts except the undertail coverts are black with the same scaly appearance as the lower back; the coverts are plain black. Juveniles' scaling is mostly ochraceous with some white on the breast and their crest is blackish without blue.

分布与栖息地
The banded ground cuckoo is found in the Chocó Ecoregion on the Pacific slope of southern Colombia and far northern Ecuador. It is "rare and localized, and occurs at very low density throughout its distribution." It inhabits wet to very wet tropical primary forest. In elevation it mostly ranges between 700 and 1,200 m (2,300 and 3,900 ft) though it has been observed both higher and lower.

Burchell's Starling
Lamprotornis australis
A large, long-tailed, iridescent blue-green to purple glossy starling with barred wings, and a round-tipped tail. Pairs, groups, and small flocks are resident in dry savanna, especially near thorn trees, where they have become common in camps and often associate with humans. The species feeds on the ground, walking with long strides and sitting low in trees, searching for insects, small vertebrates, and plant matter to eat. The similar Meves’s Starling differs from Burchell’s Starling by being bluer and smaller, with a more strongly graduated tail that is proportionately longer.
Lowland Akalat
Sheppardia cyornithopsis
A small shy akalat found in the lower levels of tall forests, often in dark shady areas near water. Note the reddish-brown back and wings, the gray face, and the bright red-orange chest contrasting with a white belly. Almost always found in lowland forest, but a few local populations are found higher up in the foothills. Within its range, most likely to be confused with Forest Robin, but note Lowland Akalat’s plain gray face and distinctive vocalizations. Song is a series of clear, melancholy whistles given with slight pauses in between, “wheeer, gowheer,” as well as faster, more resonant and metallic series of whistles.
Black-winged Ground Dove
Metriopelia melanoptera
Rather plain, medium-sized dove of the Andes and foothills. Often fairly common on open grassy and stony slopes, at bogs, around animal corrals, and villages in agricultural areas. Usually in pairs or flocks, sometimes mixed with sierra finches and other seed-eating birds. Feeds on ground, but often perches on prominent rocks; flushes with a loud rattling wing whistle. Note diagnostic orange teardrop under eye and white “shoulder” flashes that show best in flight. Smaller than Eared Dove, without big black spots on wings.
