Lower Tamar Lake

Quick visit produced good if not distant views of at least 3 Kingfishers, two headed past the hide but were to quick for me and my lens, only this record shot as some sort of proof. Another on the far bank from the hide sat high in a small tree ocassinally flying over the lake, were it would hover at about 10 ft before diving close to the water but never in. Could it have been chasing and catching dragonflies? Too far to tell withouth the scope.
