Images taken the two previous days were a bit confusing as the black bill tip coupled with an 'apparent' diffuse trailing edge to the wing gave it a 'Common' feel.....
These three images were from a consecutive burst and it's only at the extremes of the wing-beat that the 'solid' edge is convincingly apparent. The long tail streamers and translucent primaries (all of them) are there though!
The upperwing shows the classic plain grey appearance. I just love Terns as they bank with the tail feathers splayed out :-)
A 'Black' would be nice? I keep saying that......
