These photos are of the subspecies N. h. cearae which is paler than the nominate subspecies found further south. As its name suggests it is a smallish nightjar.

On this rocky outcrop at Morada Nova there must have been at least a dozen birds

We found two nests or rather scrapes in the sand or in a hollow of the rocks. Photo 4 shows a bird just returning to sit on its egg. The clutch seems to be of a single egg. Curiously, the birds sit on their eggs to keep them cool during the heat of the day.

There are recordings on xeno-canto, a distribution map from NatureServe and additional information available via Avibase.
