Another sound in the night

One of my hobbies is to record the sounds of the night around my farm, and also in wild country further west.

I recorded this sound a few months ago.

It is not a sound I have heard before, and I have been recording audio for several years now.

I suspect it is an owl or other bird, but I have not matched the sound to any online bird recordings.

The owl commonly found in this area is the boobook, which sounds very different from this.

This sound happened only once that night, and did not repeat on nights either side of the recording date.

I am keen to know – any ideas?

EDIT: I have since been told it is one of the sounds made by the boobook owl.
