Marañon Crescentchest

Melanopareia maranonica

Gorgeous little bird with a small range in the Marañon Valley of northwestern Peru and adjacent border areas of Ecuador (south of Zumba). Note the black mask, white eyebrow and throat, rich chestnut underparts, and white edges to wing feathers. Similar to Elegant Crescentchest, but wings lack chestnut patches and are more strongly marked with white; ranges do not overlap. Marañon Crescentchest inhabits arid scrub where it stays low, often on the ground. Typical song is a series of 20 or more evenly spaced clicks.

识别特征

The Marañón crescentchest is 16 cm (6.3 in) long. A female specimen weighed 23 g (0.81 oz). The male's crown and nape are black and its back and rump grayish olive. The chin and throat are white or light buff, and the throat is bordered on its sides and bottom with darker buff. It has broad black band just below the throat that merges into a chestnut breast; below the breast it is tawny. The female has a similar pattern. However, the black band is narrower and the underparts from that band to the tail are an ochraceous tawny.

分类信息

The crescentchests (genus Melanopareia) were previously included in family Rhinocryptidae, the tapaculos. A 2010 publication confirmed earlier work and created their present genus. The Marañón crescentchest is monotypic. It and the elegant crescentchest (Melanopareia elegans) might form a superspecies.

行为

The Marañón crescentchest's diet has not been described; it is presumed to be insects and perhaps seeds and other vegetable matter. Nothing is known about the species' breeding phenology, but its nest is assumed to be a cup like those of other Melanopareia species.<p>The Marañón crescentchest's song is a "series of rich notes: tu tu-tu-tu'tu'tu'tu'tu'tu'tu'tu" [1]. It has a variety of calls [2].
