Australian Owlet Nightjar – Calls

The Australian Owlet-nightjar (Aegotheles cristatus) is small nocturnal bird found throughout Australia and also in southern New Guinea. This adaptable species can be found in many different habitat types, almost anywhere there are suitable hollows for roosting and nesting. Owlet-nightjars can be difficult to locate during the day as they hide in their roosts, however, they can occasionally be seen sunning themselves at the entrance to a hollow.

The best way of determining the presence of this species is listening for their calls at night. Australian Owlet-nightjars make a variety of sounds, the most commonly heard calls include a series of soft churring notes. The calls of this species are one of the most commonly heard sounds of the Australian bush at night.
