Bryster, that seagull could take Godzilla! lol. But seriously, I did the following logic and the seagull seemed big... I pose the logic here so that you can correct me if I'm wrong... The windows are all the same size, the man farthest from the camera could easily fit through one side of an opened window. The seagul seems to me to be almost as tall as the closest window to him. Did that make any sense?
