Genus Machaeropterus

Club-winged Manakin - Like several other manakins, the Club-winged Manakin produces a mechanical sound with its extremely modified secondary remiges. The manakins have adapted their wings in this odd way as a result of sexual selection. Charles Darwin noted how females could cause evolutionary change simply by the influence of their mating preferences. Thus, in manakins, the males have evolved adaptations to suit the females' attraction towards sound. Wing sounds in many manakin lineages, however, have evolved independently. Some species pop like a firecracker, and there are a couple that makes whooshing noises in flight. The Club-winged Manakin, with its unique ability to produce musical sounds, is indisputably the most extreme example of sexual selection in manakins.

Fiery-capped Manakin - It is found in the southern Amazon Basin of Brazil, southeast Peru, and northern Bolivia; also Venezuela. Its natural habitat is subtropical or tropical moist lowland forests.

Striped Manakin - It is found in Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
