About Catamblyrhynchus diadema Lafresnaye, 1842
The plushcap, with the scientific name Catamblyrhynchus diadema Lafresnaye, 1842, reaches around 14 cm (5.5 in) in total length. Males have an average weight of 14.9 g (0.53 oz), while females average 13.4 g (0.47 oz). This species has a chestnut-colored body and a golden-yellow forecrown, which is the soft plush structure that gives the bird its common name. The area from the nape to the wings is black. Males and females have similar plumage, though males are slightly larger than females. Juvenile plushcaps are simply duller-colored versions of adult birds. Two recognized subspecies have distinct traits and ranges: C. d. citrinifrons, which occurs in Peru and has a paler cap, and C. d. federalis, which occurs in coastal Venezuela and is brighter in color than the nominate subspecies C. d. diadema. Plushcaps inhabit montane forests or secondary woodlands associated with Chusquea bamboo, which they use for foraging. They reside at high elevations, ranging between 2,300 and 3,500 m (7,500 to 11,500 ft).
