Stomach contents comprised large insects including five grasshoppers (Orthoptera) and a wasp (Hymenoptera). Another sighting of the species, on 2 October 2015 , from Camp Lemonnier is available on eBird ( P. Kaestner ; http://ebird.org/ebird/view/checklist/S25404346). We did not observe the species during the 2016 survey. The specimen record and our observations indicate that the species may be more seasonally common than thought , with more detailed observations being warranted to further document the status of Plain Nightjar in Djibouti .
