The screeching one evening while on holiday was quite distinctive, and persistent. We could hear it from indoors, so we ventured out in the dark to explore, and were rewarded with the sight of two baby owls sitting in a tree just a few feet away. Based on their size and colouration we reckoned they were Tawny owls, and they sat there for quite a few minutes, calling until a parent flew in to check on them briefly before disappearing again.
Sadly we only saw them on that one night. Although we heard them for several nights afterwards, they clearly didn’t want to come close enough to be photographed again!
