Description

The New Zealand owlet-nightjar was the largest species of owlet-nightjar, weighing an estimated 150–200 g. The species was also either flightless, as suggested by its small wings, or a very poor flier (the species has a strong keel). The diet probably consisted of invertebrates, as well as frogs and lizards.

Despite a small number of reports of small owls being found in the 19th century that may have been New Zealand owlet-nightjars, the species is thought to have become extinct around 1400 AD.
