Medium-sized typical nightjar, with a strong rufous collar. Both sexes have small pale marks in the outer wing and at the tail corners. Found in a variety of open habitats, including woodland, savanna, cultivation, and forest edge. Calls are a distinctive series of whistles: “dear lord deliver us!” and a simple series of low “chwaa” notes. Most similar to Rufous-cheeked Nightjar, but darker, with a brighter and more distinct rufous collar. Male has less white in the wing than Rufous-cheeked Nightjar.
