Seen it happen in Greenock town center ,although I booted the seagull about 20 ft in air ,it was trying to kill a wee squeaker running about road another older lady hit the seagull with her bag . I got hold of the wee bird and put it out of harms way but the seagull went right after it soon as left the scene . The video it looks like it's a pretty young bird maybe 4 weeks old .seagulls they are the real rats with wings .
