You men are funny, but Jim V. and then Ralph got the correct diagnosis.
However, when I chimped that shot on the camera, my first thought was that the shutter blew.....fired another shot, and it was OK. Only then I realised what must have happened.
you can definitely tell it's a gull, with the shape of the wing and the gray middle and white outer edging
a blown shutter means a straight line across the frame, or a black shot or a wildly overexposed shot, not like a white clouds of dust on the image hehe
to me it looks like the duck is simply breaking the sound barrier and as that is much more likely than the rare chance for a blown shutter i'm surprised that was not your first thought
Nah, the duck's not breaking the sound barrier, but the gull is. And if it's a supersonic gull, just think of the hypersonic velocity of its wings! Cavitation, anyone?
