Elegant Crescentchest
Melanopareia elegans
A striking little bird, shaped like a robust gnatcatcher. Note the bold black-and-buff head pattern, black chest fading to rufous flanks, and bright rufous on the wings. Tail is long and narrow. Unmistakable if seen well, but compare with Marañon Crescentchest, which has silvery wing edges and more richly-colored underparts. Secretive; singles or pairs skulk in dense thickets and understory of dry woodland and second growth, up to 2,300 m. More often detected by song; listen for a series of loud, popping chip notes.
Identification
The elegant crescentchest is 14.5 cm (5.7 in) long. Males weigh 16.0 to 20.2 g (0.56 to 0.71 oz) and females 15.5 to 19.0 g (0.55 to 0.67 oz) Males of both subspecies have a black crown, nape, and mask and a creamy supercilium. The back and rump are olive-brown. Its throat is white or pale buff that is darker around the margins and a black "bib" is below it. The upper chest is dark chestnut fading to tawny on the flanks and belly. The nominate female is similar, but the crown is sooty and there is no dark chestnut on the chest. The female M. e. paucalensis is like the nominate except that its crown is the same olive-brown as the back.
Taxonomy
The crescentchests (genus Melanopareia) were previously included in family Rhinocryptidae, the tapaculos. A 2010 publication confirmed earlier work and created their present genus. The elegant crescentchest and the Marañón crescentchest (Melanopareia maranonica) might form a superspecies. Two subspecies of elegant crescentchest are recognized, the nominate Melanopareia elegans elegans and M. e. paucalensis.

Range and habitat
The elegant crescentchest is found discontinuously along the coast of Ecuador from Manabí Province south into Peru as far south as the Department of La Libertad. The nominate is in Ecuador and M. e. paucalensis is in Peru, and birds in far southern Ecuador might be intergrades between the two subspecies. Its principal habitat is scrub and undergrowth in semi-arid woodland; it can also be found in more humid disturbed areas. In Ecuador it ranges from near sea level usually to 2,000 m (6,600 ft) and locally to 2,400 m (7,900 ft). It Peru it reaches only as high as 1,700 m (5,600 ft).

Behavior
The elegant crescentchest's diet has not been reported. It forages alone by hopping through dense cover on and near the ground.<p>Almost nothing is known about the elegant crescentchest's breeding phenology. Three nests have been described. They were constructed of dry strips of cactus and weeds, were enclosed with a side entrance, and hidden on the ground.<p>The elegant crescentchest's song is "a series of..."chuck" notes" [1]. Its scold call is "a dry penetrating churr" [2].

Other Birds
Banded Woodpecker
Chrysophlegma miniaceum
Small but brightly-colored woodpecker with a spiky crest. Slight variation across its range, but all birds have a dark orangish face, dark chestnut wings, black-and-white-striped underparts, and a dark tail. Female duller overall, with a plainer face. Inhabits lowland and foothill forests, edges, and gardens, where it can be reasonably common. Often seen singly, but can be encountered in closely-foraging pairs. Favors tall thick trunks. Gives sharp “kek” or “week” call notes. Difficult to confuse with any other small woodpecker.
Band-tailed Antbird
Hypocnemoides maculicauda
Small short-tailed antbird found around still and slow-moving water in humid forest. Medium gray; tail black, with a broad white terminal band. Males have a black throat; females are lighter underneath. Forages low at the water’s edge and in vegetation overhanging the water around oxbow lakes and streams. The male’s song is an ascending series of whistles accelerating into a harsh descending series; it can be attention-grabbing with its grating snarling ending.
Falcated Duck
Mareca falcata
An East Asian teal-like duck. Males are distinctive, with an iridescent head that flashes green and copper, a silvery body with distinct scalloping, extremely long curved tertials, long pale scapulars, and a triangular white throat patch outlined in dark green. Brownish females resemble female Gadwall but have a dark bill. Breeds in northern interior marshes and winters on rivers, lakes, and coastal wetlands, often in flocks with other ducks.
