A brief stop at West Ferry first thing produced a single Whimbrel feeding along the distant shoreline. Through the telescope, the bird's 'jiz' was obvious. What was also notable was that it was clearly submissive to two nearby Oystercatchers, taking flight when either of them lunged at it. I don't think I have ever seen Oystercatchers intimidating Curlews in this way, and wondered if this might be a helpful identification feature at long range.
