oi! gerrof my garden bench!

So, another day working at home, with not a lot worth photographing going on, apart from this damn pigeon sitting on the garden bench. We were wondering why there was a rather large amount of poo on the bench, and thought it was due to the positioning of the bench under the numerous wires strung across the garden. But no, it seems like they're just sitting and s*itting. gah!
