The double-collared crescentchest (Melanopareia bitorquata) is a species of bird in the family Melanopareiidae. It is found in eastern Bolivia and adjacent areas in Brazil.[1][2]
The crescentchests (genus Melanopareia) were previously included in family Rhinocryptidae, the tapaculos. A 2010 publication confirmed earlier work and created the present genus.[3][4] The International Ornithological Congress (IOC) recognizes the double-collared crescentchest as a species.[1] However, the South American Classification Committee of the American Ornithological Society (AOS) and the Clements taxonomy consider it to be a subspecies of collared crescentchest (Melanopareia torquata bitorquata).[3][5]
Descriptionedit
The double-collared crescentchest has a similar pattern to that of the collared crescentchest but the colors are deeper or different in several areas. Its upper parts are olive brown rather than brown and the underparts a deep ochre instead of buff. It has the same black-bordered white supercilium but the "collar" at the back of the neck is a deeper rufous shade and has a black border.[6]
Distribution and habitatedit
The double-collared crescentchest is found in Bolivia's Santa Cruz Department and the western edge of Brazil's Mato Grosso State. It inhabits cerrado, a biome characterized by a mix of savannah and woodlands.[6]
Behavioredit
The double-collared crescentchest's diet has not been described but the species is assumed to be insectivorous.[6] Examples of its song are here [1].
Statusedit
The IUCN has not assessed the double-collared crescentchest.
