Bombs away.

I was hoping this very distant heron would fly nearer to give me a better picture. In the few minutes I waited, the poor bird was dived on about twenty times by aggressive gulls. Even the deployment of dirty bombs wasn't enough to shift the grey (and now with added mucky white) one from its perch.
Probably not quite what was intended for the large theme, but it was a very big seagull dollop.

Many thanks to BobsBlips for hosting.
