Continued my mission to find Little Owls today, and found another site - just as I started heading back home! Went back in the evening as I thought that there might be Barn Owls nearby (there weren't this evening), and there was a Little Owl again. However, I think that it may be the other one of a pair as the markings look a bit different.
Whilst out, I came across a clutch of Yellowhammers. One day I'll get a decent shot of one of these birds!!
