The Australian owlet-nightjar (Aegotheles cristatus) is a nocturnal bird found in open woodland across Australia and in southern New Guinea. It is colloquially known as the moth owl. It is the most common nocturnal bird in Australia, and despite suffering from predation and competition by introduced species it is not considered threatened. [1]
Nightjars can occupy all elevations from sea level to 4,200 m (13,800 ft), and a number of species are montane specialists. Nightjars occupy a wide range of habitats, from deserts to rainforests but are most common in open country with some vegetation. [8] The nighthawks are confined to the New World, and the eared nightjars to Asia and ...

[3] [4] Although frogmouths were formerly included in the order Caprimulgiformes, a 2019 study estimated the divergence between Podargus and Batrachostomus to between 30 and 50 mya and forming a clade well separated from the nightjars and being a sister group of the swifts, hummingbirds, and owlet-nightjars.
Apodimorphae is a clade of strisorean birds that include the extant families Trochilidae (hummingbirds), Hemiprocnidae (treeswifts), Apodidae (swifts), Aegothelidae (owlet-nightjars), and many fossil families. This grouping of birds has been supported in a variety of recent studies.
