Made a trip to Dunge today. With heavy rain forecast this was more in hope than expectation. At the ARC Pit I saw a Great White Egret in flight and a Hobby flashed past. We thought we'd try the patch before the deluge but as we got out of the car it was starting to rain a bit and I made the bad decision to leave the camera behind. We sheltered on the right of the first hide and scanned the patch. We saw a couple of Arctic Terns among the Common before my eagle-eyed companion managed to pick out a Roseate Tern, which then proceeded to fly towards us along the shore edge right past the hide. I ran for the camera and managed a record shot after chasing it along the shingle. I was reflecting on the pictures that might have been, when the message came of 2 White-winged Black Terns on Burrows Pit. We hurried to the reserve where we had good but fairly distant views of these stunning birds in pouring rain, which sent us home earlier than usual.
