A warm one last night and we had the balcony door open and heard a very strange bird call from a tree not ten yards away. I have tried to identify it and can only find one with a similar call, a Spotted Owl, it is a very sweet call. Pretty loud too, from only ten yards away.
The problem is that it is a near-threatened species owl, from the USA.
An escaped pet I wonder, it would have to be a captive bred bird because it appears on the Cites list.
