The prigogine nightjar ( Caprimulgus prigoginei ) is a little-researched bird species from the nightjar family (Caprimulgidae). It is found in the eastern Democratic Republic of the Congo and possibly in Cameroon , the Republic of the Congo, and Gabon . The type epithet honors the Russian-Belgian ornithologist Alexandre Prigogine (1913–1991), who in 1955 collected the only known specimen.

features

The holotype , an adult female, measures 19 cm. The upper side and the elytra are brown with dark brown, yellow-brown and dark yellow spots and speckles. There is no neck collar. The chest is spotted brown with a yellow-brown and dark yellow banding. The belly and flanks are lighter with brown banding. Small, dark yellow spots can be seen on the second, third and fourth outermost wrist wings. The outermost tail feathers have narrow, white tips, the remaining tail feathers have narrower yellow-brown or dark yellow tips. The iris is not described. The beak is blackish, the legs and feet are reddish brown. The district call may consist of a series of short “tchoc” tones.

Habitat and way of life

The type specimen was caught in the transition zone between wooded lowland and mountain regions at an altitude of 1280 m. Nothing is known about the way of life. The diet probably consists of insects.

status

The Prigogine nightjar is classified by the IUCN in the “endangered” category . The specimen collected by Alexandre Prigogine in August 1955 comes from Malenge in the Itombwe Mountains in the province of Kivu in what is now the Democratic Republic of the Congo. The preparation is kept in the Royal Museum for Central Africa in Tervuren near Brussels. Assumptions that this species still exists are based on sound recordings of the voice from the Itombwe Mountains in 1996 and identical sound recordings from Gabon in 1985, from the north of the Republic of Congo in 1996 and from southeastern Cameroon in 1997. The The main threat comes from habitat loss through deforestation.
