Since it’s a pretty miserable day out there, I’ve been tidying up a few photos from recent trips. In the process, I stumbled across this bird (from Bulgaria a few weeks ago), which provoked some discussion in the field at the time, and never conclusively got identified. The shots aren’t great, against a rather murky grey sky, unfortunately.
However, given the limitations of the pics, what do you reckon it is? I have an idea, but am not convinced. So, leave me a comment with your ID, and explain why!
