Plain nightjar

The plain nightjar (Caprimulgus inornatus) is a species of nightjar in the family Caprimulgidae. It breeds in the southern Sahel, Southern Sudan, the Horn of Africa and the southwestern Arabian Peninsula. It migrates to lower latitudes - including central Congo and northern Tanzania. A rather plain looking nightjar with grey-brown, brown, and rufous morphs. Males have white spots on primaries (4 feathers), large white corners to tail, and no white on the throat (may show black spots on the crown and scapulars like Star-spotted Nightjar). Females have buffy-brown wing spots, and no white on the tail.

Conservation status
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
