Hi Aaron,
Photographing gulls can be a rather entertaining process; unlike many other bird types they are content to flock about you, particularly if they think there is food on offer.
With this photograph the immediate thing I want to do is crop some of the foreground, and also remove the bird at the top that has its wings in front of its face. This can be easily done by using the clone tool.
Now, if you get the chance there is another technique that I would
try when it comes to photographing these birds. See if you can organise
yourself a remote trigger for your camera (there are several versions available
including wired and wireless options) and then try placing the camera on a very
low tripod with a wide-angle lens.
Set the focus and exposure to manual mode
and then move back and start throwing the few hot chips in the direction of
your camera. Rather than chasing the birds to get a photograph I think you will
suddenly discover that you can capture great photos of their social interaction,
particularly as they argue amongst themselves.
Just one small tip; wrap some plastic or Gladwrap about the camera prior to letting the gulls get close. Guano can be rather messy to clean off a DSLR!
