Brighton: the British seaside town of chips-in-newspaper helter-skelter fun, the pebble beach Londoners flock to in good weather, the ideal boutique, boho-chic summer city break. But in December to February? It’s low season and things are a bit quieter – unless, that is, you’re a bird. As tourists desert Brighton’s famous pier in winter, starlings from across the South Downs move in. At dusk they amass in their hundreds of thousands, performing dazzlingly balletic murmurations, rippling like water in the sky, then, as if on unseen cue from Mother Nature, they pour beneath the pier to roost in one great swooshing torrent.
