Bitterns are fairly common but very discreet winter visitors, blending with the reedbeds most of the time. Sometimes, though, they are caught up in fairly open areas and it's really very funny watching them as they try to look like reeds in the middle of nowhere! This one was on the fringe of vegetation, and a few seconds later it walked into the safety of the nearby reedbed, just in front of the Vravrona Archaeological Museum.
