The Common Terns have taken to sitting on the platform where the herons like to fish at Warnham Nature Reserve. I walked into the Heron Hide having seen a large brown bird from a hide further down the millpond landing in the reeds near there, thinking it might be the Purple Heron spotted a few days earlier. No sign of the big brown bird but I was greeted by the sight of a heron being repeatedly dive-bombed by a pair of terns who were trying to force it off the platform. It was attempting to catch fish but their repeated attacks were preventing it from doing so until suddenly between attacks it managed to catch and devour quite a sizeable fish before eventually the terns succeeded in driving it away!
