Homing Pigeon

On my way home from work today I came across a pigeon that did not fly away as I got close, he/she was really trusting. On closer inspection it was in a poorly state but seemed to be looking for food. I took quick video with my trusty camera and you can see the footage here.

On reflection I think he was probably a tired homing pigeon, as I noticed he had no less that 4 rings on his two legs, and I have never see a feral pigeon with rings. He also looked in really good state i.e. his plumage was neat and tidy no tufty bits.
