The CEO of the British Trust for Ornithology, Juliet Vickery, describes an encounter with a patrolling male woodcock 30 years ago, watching it circle its territory from high in the sky. Apart from this display these waders are very hard to see, usually inhabiting dense woods and heathland, which also makes them hard to monitor. However thanks to generations of volunteer observers, we know that the distribution of breeding woodcock in the UK is sadly less than half of what it was in the 1960s.
