Click on the picture above & press play when it opens to see what the Tube looks like to feathered commuters who are only about five inches high. I don't know how he managed to take it without more people looking at him. He said "Did it at night coz I figured prob less obvious - till I found out a pigeon with a cam round it's neck is totally obvious - esp at night."
He's also done an excellent job keeping his head relatively still. I think it's a cool little video and perhaps people will stop calling pigeons vermin now. When did you ever see a rat with a video-cam? Pigeons are in a league of their own as fare evading commuters, although sometimes I'd rather they didn't sit on the seats!
