What is the Australian Owlet Nightjars predator?

There is no bird species known as "Australian Owlet Nightjar". It seems you may have misheard or confused the name. Could you clarify the bird species you are referring to?

To help me understand, please provide:

* The full name of the bird species: Is it an owlet-nightjar, or a specific species of nightjar?

* Any other details you remember: What did it look like? Where did you see it?

Once I have this information, I can help you find the predators of that specific species.
