New Caledonian nightjar
species of bird in the Caprimulgidae family

The New Caledonian nightjar (Eurostopodus exul) is a poorly known species of nightjar in the family Caprimulgidae.
It is endemic to New Caledonia.
Description
The species was first described by Ernst Mayr in 1941, from a specimen collected in New Caledonia on the Whitney South Sea Expedition in 1939. Mayr initially described the species as Eurostopodus mystacalis exul, believing it to be a subspecies of white-throated nightjar.
Based on the type specimen, this nightjar has silvery-grey plumage with dark blotches and streaks, with a black crown and dark, grey-brown underparts. It lacks the nuchal collar seen in some Caprimulgiformes, but does display a white patch on its throat.
Conservation
It is considered possibly extinct, as it is known only from the holotype which was collected in 1939.
The specimen was of a bird taken in coastal savanna. The possibility of decline in population was probably caused by predation by introduced cats and rats, alongside habitat destruction.
The public source identifies “New Caledonian nightjar” as species of bird in the Caprimulgidae family. This brief keeps that definition visible, then builds a research path around Caledonian, nightjar and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “New Caledonian nightjar”, the useful work is to connect “species of bird in the Caprimulgidae family” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 9, 2026. The linked authority identifier is Q15879807. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1941 and 1939.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
