The Senegal furry beak ( Lybius dubius ), also known as the furry beak bearded bird , is a species from the African bearded bird family (Lybiidae). The species occurs in Africa north of the equator. Because of this northern distribution area, the Senegal furry beak, together with the purple mask bearded bird, is one of the bearded birds scientifically described as early as the 18th century.
No subspecies are distinguished for the Senegal furrowbill. The IUCN classifies the Senegal furrow bill as not endangered ( least concern ).
Appearance
The males reach a wing length of 10.7 to 11.9 centimeters. The tail length is 7.8 to 9 centimeters. The beak is between 3.1 and 3.7 inches long. Senegal furrows are thus one of the largest species within the tooth-bearded bird genus. They weigh about 100 grams. Females and males have similar body measurements. There is no pronounced sexual dimorphism .
Males and females are shiny black on the top of the body from the forehead to the control feathers. They only have a white spot on their lower back. The cheeks and the ear covers are red. A very narrow black stripe divides the red face and runs from the upper beak base to the sides of the neck. The chin and throat and the sides of the neck are bright red. At the base of the beak there are black, bristle-like feathers that point forward. A black band runs across the center of the chest. The chest and the middle of the abdomen are red and interspersed with white. The thighs, the rear part of the flanks and the under tail-coverts are black. The strong beak is horn-colored to yellow and the upper beak can also be overlaid with orange or red. The featherless skin around the eyes is yellow, the eyes are pale to bright yellow. The legs and feet are orange-yellow to reddish yellow.
Fledglings are feathered similar to the adults, but are more dull overall.
It can be confused with the double-toothed bearded bird , which is smaller and does not have a black chest band. The black breast furrow beak is black on the throat and chin.
Distribution area
The Senegal furrowbill is a West African species of bird and occurs from the south of Senegal and Gambia as well as Guinea-Bissau to the south of Mali, Burkina Faso, the southwest of Niger, the north of Nigeria and the north of Cameroon. In the south, the distribution area extends to Guinea, the Ivory Coast, Ghana, Togo, the north of Benin, Nigeria, Cameroon and the west of the Central African Republic. In their altitude distribution, Senegal furrow beaks are limited to locations below 1,500 meters.
Way of life
The Senegal furrowbill inhabits relatively dry regions that have a population of large trees such as African baobab trees , acacias and figs and in the vicinity of which there are thickets. It also colonizes the edges of cultivated land, abandoned farms and plantations, gardens, isolated forest areas and secondary forest. It has not yet been investigated what effects desertification and deforestation have in the south of its range. It cannot be ruled out that this will result in an expansion to the south. The Senegal furry beak is a showy species of bird that occurs in small flocks of up to five adult birds. The food spectrum consists mainly of fruits. It probably also eats insects. However, so far there are hardly any details about its way of life and its reproductive biology.
