I took this a couple days ago and believe it to be the locally very common Glaucous Winged Gull. Cropped from a horizontal. 50D, 500mm f/4, at f/4, 1/250 and ISO400. Dave
Liked the low angle, wing blur and the water splash a lot. One thing that bothers me is the contrast. You might want to play with the contrast in RAW conversion. Nice timing.
