Herring gulls live for 20 years, mate for life, and are intelligent social birds. This is a place to appreciate positive interactions with the little skwarkers. They are on the red endangered list in the UK and a protected species, so let's all be nice to them.
A few years back, I lived in a sixth floor apartment and could see the roof of the building across the street. A mother seagull raised a pair of chicks there. They look like the cutest little idiots while they're trying to learn to fly--just hopping and flapping, hopping and flapping.
