Just thought i'd add this to the rescue forum. Goes back a few years, but anyway.
About 1.00am one morning, we were woken up by splashing in our pool. Went down to look, and in there was a boobook owl, in trouble, tiring quickly. I jumped in and managed to get it out. We placed it in a box with a towel etc. We contacted our vet, who is also a wires volunteer. He came down and we can happily report this beauty was given the all clear and released back to the wild,
