As a boy, Jon Day was fascinated by pigeons, which he used to rescue from the streets of London. Twenty years later he moved away from the city centre to the suburbs to start a family. But in moving house, he began to lose a sense of what it means to feel at home. Returning to his childhood obsession with the birds, he built a coop in his garden and joined a local pigeon racing club. Over the next few years, as he made a home with his young family in Leyton, he learned to train and race his pigeons, hoping that they might teach him to feel homed. Having lived closely with humans for tens of thousands of years, pigeons have become powerful symbols of peace and domesticity. But they are also much-maligned, and nowadays most people think of these birds, if they do so at all, as vermin.
