Seagulls are dedicated city dwellers. They wake the city up in the morning and they know what its rooftops and backyards look like. In the city they find hide-outs where their human neighbors never set foot. They find viewpoints from which to spot danger. They find shelter for their young ones, and human rubbish with lots of leftovers to eat. In Seagull City we experience urban life through the eyes of the seagulls, and investigate the co-existence between people and birds in an environment that we usually consider as ours.
