Melanopareia maranonica
The Marañón Crescentchest (Melanopareia maranonica) is a small, striking passerine bird, measuring approximately 15-16 cm (5.9-6.3 in) in length and weighing around 20-22 grams. Its most distinctive feature is a prominent black crescent-shaped band across its otherwise rufous breast, contrasting sharply with a white belly. The head is slate-gray with a fine white supercilium and a black malar stripe, while the back and wings are olive-brown. This species is monomorphic, with males and females...
This species primarily inhabits arid scrubland, dry tropical forest, and deciduous woodland, often favoring dense undergrowth and thorny thickets. It is typically found at elevations ranging from 200 to 1,500 meters (650-4,900 feet) above sea level.
Its diet consists predominantly of insects and other small arthropods, which it forages for by gleaning from the ground and sifting through leaf litter.

It is diurnal, with peak activity in the early morning and late afternoon, often roosting hidden within dense v...
The Marañón Crescentchest is strictly endemic to the arid and semi-arid Marañón River basin and its immediate tributaries, spanning northern Peru and extreme southern Ecuador. Its primary distribution lies within the dry inter-Andean valleys of Peru, particularly in the regions of Cajamarca, Amaz...
