The Dotterel is still present this evening and showing very well around the limestone pavements. Thanks to Mike Nesbitt for the photo above. See Rob Sandham's pictures here - http://www.webirdnorthwales.blogspot.com/
As Rob and Mike have testified the bird will walk towards you if you keep your distance. No need to chase it aound to get a few feet closer like some 'big lens' photographers have apparently been doing!
