A photographer has captured the mesmerising sight of thousands of wader birds flying in Norfolk. Photographer and guide Paul Goldstein says he has visited Snettisham Nature Reserve literally hundreds of times, yet is always intoxicated by the spectacle. The Wimbledon-based snapper explains: "Several times a year vast murmurations of waders, particularly knots, perform magical formations and patterns over the Wash's shallow waters in North Norfolk. "When the early light catches thousands of wings simultaneously, combined with the haunting rustle of countless wingbeats, it is pretty close to avian witchcraft. "It is an RSPB flagship just round the corner from Springwatch's autumn and spring stronghold, and it's easy to see why."
