The five-colored bearded bird ( Capito quinticolor ) is a species of bird in the American bearded family. The species occurs in a small area in northern South America. No subspecies are distinguished. The IUCN classifies the five-colored bearded bird as endangered ( vulnerable ), as its habitat is becoming increasingly smaller due to deforestation.

Appearance

The males of the five-colored bearded bird reach a wing length of 8.5 to 8.2 centimeters. The tail length is 4.1 to 4.5 centimeters. The beak length is 2.0 to 2.2 centimeters. The males weigh an average of 61.4 grams. Females have similar body dimensions. However, there is a striking sexual dimorphism in the plumage color.

The males have a black forehead. The parting extends to the nape of the neck and is bright red. A wide, black band runs from the beak over the eyes and the ear covers to the neck. There is a yellow, V-shaped badge on the otherwise black and blue coat. The chin and throat are white to cream in color, the chest and the sides of the chest are yellowish to gold in color. The center of the chest is the most intense yellow, in some individuals almost orange. There are black, teardrop-shaped spots on the flanks, the legs are sooty black with yellow feathers. The feathers of the under tail-coverts have a black center and are yellowish-white on the sides and the tip. The strong beak is relatively short and pointed. The featherless eye region is slate-colored, the eyes are brown to chestnut-colored or red-brown. The legs and feet are gray, blue-gray, or dark gray.

The females have no red head. They are black on the upper side of the body with fine yellow vertical stripes. The throat is white with fine white spots. The chest and belly are yellow, the spots here are larger and more teardrop-shaped.

It can be confused with the whiskered bird , which does not occur west of the Andes and whose males do not have a red, but a golden-yellow head.

Distribution area and existence

The five-colored bearded bird has only been observed in 14 locations in Colombia and northern Ecuador. Its distribution area here includes plains and the lower mountain regions up to a height of 575 meters. The species is generally considered rare and is relatively common only in two places in the Ecuadorian province of Esmeraldas and in Nariño in southwest Colombia. The forest is being selectively cut down at one of these two locations.

The loss of habitat in the Ecuadorian range was around 3.8 percent in the first decade of the 21st century. In Colombia, too, the loss of habitat has recently increased significantly. The cause is the increasing conversion of the primeval forest into oil palm plantations , an increased use of wood, the cultivation of cocoa and the increased search for gold. This has led to an increasing population density in this region and a significant decrease in the population of the five-colored bearded bird. For this reason, the IUCN classifies the five-colored bearded bird as endangered. The world population is estimated at 85,000 to 250,000 sexually mature individuals.

Way of life

The way of life of the five-color bearded bird has so far only been poorly researched. Its habitat are moist to wet forests of the lowlands. It occurs here at the edges of the forest as well as in tall secondary forests. It hangs mostly in the treetops, but while foraging for food it can also come down to 2.5 meters above the ground. Occasionally he joins flocks of other bird species. The breeding season probably falls between April and August.
