||19 cm. Small nightjar, described from one female specimen. It looks vaguely similar to female Fiery-necked Nightjar C. pectoralis. Voice It is presently not known how to identify this species but if sound recordings of unidentified nightjars prove to be of this species, then its song is very similar to C. natalensis.

This enigmatic species remains known with certainty from a single specimen, although sound recordings indicate that it may be more widespread. It is thus very difficult to assess its status. It is currently classified as Endangered because it has a very small range, within which forest clearance is likely to be causing declines. If future survey work confirms its presence elsewhere, as is already being suggested in two new countries, this would significantly increase its known range and call for re-assessment of its threatened status.

|Range Description:||Caprimulgus prigoginei remains known from a single female collected in August 1955 at Malenge, in the Itombwe Mountains of the eastern Democratic Republic of Congo (Dowsett-Lemaire 2009). A sound recording of two nightjars, in Itombwe at c.1,700 m in 1996, very probably refers to this species (T. Butynski in litt. 1999). Identical tape-recordings were obtained in northern Congo in 1996 (Dowsett-Lemaire and Dowsett 1998a) and south-east Cameroon in 1997 (Dowsett-Lemaire and Dowsett 2000a), suggesting that the species may be more widespread. Additional records of nightjars that probably refer to this species (Butchart 2007) have come from Gabon in 1985 (F. Dowsett-Lemaire in litt. 2006, Brosset and Erard 1986), and Congo (Dowsett-Lemaire and Dowsett 1998a, F. Dowsett-Lemaire in litt. 2006) and Cameroon (Dowsett-Lemaire and Dowsett 1998b) in the 1990s.|

|Population:||The population of this species is assumed to be small (fewer than 10,000 individuals) based on the fact that there are no confirmed records since the original specimen was collected in 1955. It is placed in the band 2,500-9,999 mature individuals here, equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: The species is suspected to be in decline owing to the continued clearance of forest for cultivation and livestock-grazing (Omari et al.1999). The likely rate of decline has not been estimated.
