White- winged Black Tern

On Sunday 6 September, a tweet from Tony S stating there was a WWBT at Ormesby Broad had me driving over there and from the bridge by the busy road looking over to the far end we saw 2 Common Terns perched on posts and eventually the excellent juvenile White- winged Black Tern constantly flying over the water it sported a grey black back or saddle with darkish around the mid rear of the cap and a black edge to the primaries, it had typically dipping marsh tern flight and flew over tp the reeds on the left in the mid distance.
