@stux This is amazing! I wonder what triggers this behaviour.
video description
@stux a video of a seagull standing on another seagull in flight. After a while, the top seagull takes off for a few centimetres, only to land on the lower seagull's back again. Apparently there is a strong wind, so the two seagulls don't move very much relative to their surroundings.
