Wartook bird

Hey everyone,

My partner and I are stumped by a bird we heard on our recent stay at Wartook, near Horsham and the Grampians, in the Wimmera area of Victoria. He thinks he only heard it at night; I think I may have heard it in the daytime as well as in the night. We never saw it, so have no idea what it looked like.

It's call went: oooh-i ooih-i ooh-ooh.

Any ideas would be appreciated :)

Thanks,
Sue and Anthony
