The plushcap (Catamblyrhynchus diadema) is a species of bird in the tanager family Thraupidae and it is the only member of the genus Catamblyrhynchus.
The plushcap is one of the most distinctive of all Neotropical passerines in both its appearance and behavior. The plushcap was in its own family until recently when it was grouped with the tanagers. It is very distinct both physically and in its behavior. The bill is broad and black. The body is a chestnut color with a bright golden-yellow forecrown. The forecrown is made up of stiff feathers. It has been speculated that these short, dense feathers are less susceptible to feather wear and more resistant to moisture than typical feathers. This may be an adaptation for its specialized feeding mode, in which it probes into dense whorls of bamboo for its prey items (Hilty et al. 1979). Juveniles are just duller versions of their parents. They are found at high elevations from northern Venezuela south to Argentina, including the coastal mountains of Venezuela and the Andes of Colombia, Ecuador, Peru, Bolivia, and extreme northwestern Argentina. They live in montane forests and secondary forests near bamboo. They forage for insects inside the bamboo. They will eat small insects, berries, and small plant matter.
The bird is very distinct and is not confused with many other birds. It stands out from the other tanagers, only possibly being confused with the golden-crowned tanager despite the golden-crowned tanager being blue. Its natural habitat is humid montane forests and it is always found in close association with Chusquea bamboo. It is typically found at elevations between 1,800 and 3,500 m.
The plushcap was formally described in 1842 by the French ornithologist Frédéric de Lafresnaye from a specimen collected in Colombia. Lafresnaye introduced a new genus Catamblyrhynchus and coined the binomial name Catamblyrhynchus diadema. [2] The genus name combines the Ancient Greek katambluoō meaning "to blunt" and rhunkhos meaning "bill". The specific epithet is from the Latin diadema which in turn comes from the Ancient Greek diadēma meaning "royal head-dress". [3] The type locality is Bogotá in Colombia. [4] The plushcap was at one time placed in the family Emberizidae [4] but molecular phylogenetic studies have shown that it belongs in the tanager family Thraupidae. [5]
Three subspecies are recognised: [6]
The plushcap is about 14 cm (5.5 in ) long and males weigh on average 14.9 g (0.53 oz ) and females 13.4 g (0.47 oz). [7] It has a chestnut body and a golden-yellow forecrown (the plush part of the name). From its nape to its wings, it is black. The males and females look similar but the males are slightly larger than the females.
The subspecies C. d. citrinifrons is found in Peru and has a paler cap while C. d. federalis is found in coastal Venezuela and is brighter than C. d. diadema.
While the plushcap is usually quiet, when it does vocalize it has a long series of chirps and twitters.
Plushcaps prefer to live in montane forest or secondary woodland by Chusquea bamboo which they use to find food. They stay at high elevation, between 2,300–3,500 m (7,500–11,500 ft ). [1]
The diet consists of small insects, berries, and plant material, and they typically forage in small groups within mixed species flocks of wide diversity. The plushcap looks for insects by probing and pushing its bill into the stems and leaf nodes of the bamboo and prying them open. They also forage by running their bill along the stems of bamboo with a series of tiny biting motions. Plushcaps will often hang upside down while searching for the insects.
Plushcaps are considered of least concern due to their wide range in South America but it is thought that the number of individuals is declining. They tend to be common in their range. [1]
The tanagers comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds.
The giant conebill is a small passerine bird, one of the tanager family. It is closely related to the regular conebills Conirostrum though it differs in its larger size and nuthatch-like foraging habits.
The grass-green tanager is a small South America bird in the tanager family Thraupidae. It is the only member of the genus Chlorornis.
Tangara is a large genus of birds of the tanager family. It includes 27 species. All are from the Neotropics, and while most are fairly widespread, some have small distributions and are threatened. They are fairly small, ranging in size from 11.5–15 centimetres (4.5–5.9 in). This genus includes some of the most spectacularly colored birds of the world.
Typical conebills belong to the tanager genus Conirostrum. They are small tanagers (9–14 cm) found in the forests of South America. They feed in pairs or small flocks by gleaning insects from foliage.
The black-chested mountain tanager is a species of bird in the family Thraupidae.
The grey-hooded bush tanager is a species of South American bird in the tanager family Thraupidae. It is the only member of the genus Cnemoscopus. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
The white-sided flowerpiercer is a fairly common and widespread species of Flowerpiercer. Flowerpiercers are a genus of birds within the Tanager family Thraupidae, with specially adapted bills that enable them to pierce the sides of flower blossoms to access the nectar. The white-sided flowerpiercer is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The masked flowerpiercer is a species of bird in the tanager family, Thraupidae. It is found in humid montane forest and scrub in Venezuela, Colombia, Ecuador, Peru and Bolivia. Flowerpiercers got their name from the fact that they have a sharp hook on the tip of their upper mandible which they use to slice open the base of flowers to get at the nectar.
The black-capped hemispingus is a species of bird in the family Thraupidae. It is found in the Andes mountains of Colombia, Ecuador, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
The golden-collared honeycreeper is an uncommon species of Neotropical bird in the tanager family Thraupidae. It is the only member of the genus Iridophanes.
The white-winged tanager is a medium-sized American songbird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found from Mexico, through Central America, across northern South America and as far south as Bolivia.
The golden tanager is a species of bird in the family Thraupidae. It is widespread and often common in highland forests of the Andes and Venezuelan Coastal Range in north-western South America.
The black-capped tanager is one of the many species of Neotropical bird in the family Thraupidae. It lives in mountains of Ecuador, Colombia and Venezuela year-round. This bird can often be found in open landscapes, alone or in pairs, hiding under branches of trees and bushes. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
