The crescentchests are a
The crescentchests range in length from 14 to 16 cm (5.5–6.3 in), in weight from 16 to 23 g (0.56–0.81 oz) and have relatively long tails compared to the tapaculos. The plumage is striking with a distinctive band across the chest that gives the group their name.[6]
The crescentchests are birds of arid scrub. They generally forage on the ground, but their diet has not yet been recorded. Two species, the collared crescentchest and olive-crowned crescentchest, are widely distributed across central and southern Brazil, Bolivia, Paraguay and northern Argentina. The double-collared crescentchest, which was recently split from the collared crescentchest, is found in eastern Bolivia, whilst the other two species, the elegant crescentchest and Marañón crescentchest, have a more restricted distribution in Peru and Ecuador.[6]
Little is known about the behaviour of the crescentchests. The only species about which anything is known about the breeding behaviour is the olive-crowned crescentchest. That species is a seasonal breeder. The nest of that species is a 15 cm high cup made of vegetable fibres and palm fronds, hidden in grasses or low shrubs close to the ground. The clutch size is two to three eggs, the eggs are white with blotches or black spots.[6]
