About Machaeropterus deliciosus (P.L.Sclater, 1860)
The club-winged manakin, scientifically known as Machaeropterus deliciosus (P.L.Sclater, 1860), measures approximately 9.5 to 10 cm (3.7 to 3.9 inches) in length. One recorded female of the species weighed 12 g (0.42 oz). This species shows clear sexual dimorphism. Adult males have a scarlet forehead and crown, with a dusky stripe running through the eye. The rest of the head and most of the body are primarily chestnut-brown, which is lighter on the face and darker on the belly. The rump and uppertail coverts are blackish, and the flanks have mixed white coloring. The scapulars and tail are black, the wings are black with extensive white on the flight feathers, and some wing feathers are highly modified, as discussed further in the non-vocal sounds section. Adult females have an olive head with a cinnamon tinge on the face, olive upperparts, a whitish throat, yellowish olive breast and flanks, and a pale yellow belly. Both sexes have a dark brown iris, a black bill, and usually grayish pink legs and feet that are sometimes purplish. Juveniles of both sexes look similar to adult females. The club-winged manakin is distributed along the western slope of the Andes, from Risaralda Department in west-central Colombia, south into Ecuador to Pichincha Province. Small additional populations are also found in Ecuador's El Oro and Loja provinces. It lives in wet montane forest of the subtropical zone, as well as mature secondary woodland. In Colombia, its elevation range is between 400 and 1,800 m (1,300 and 5,900 ft). In Ecuador, it is mostly found between 600 and 1,600 m (2,000 and 5,200 ft), and occurs at locally lower elevations.
