Sometime ago, Dave was telling me about single "Golden Plovers" with big eye stripes - something crossed my mind (not the greatest of journeys I know!) - so I rang him & he went through the Collins guide with me on the phone & came to the conclusion that it was an AGP. I rang Brian who was at Marloes Mere, he turned up 5mins later & came to the same conclusion.
I must thank Dave & Brian for their help in confirming my suspicions about this big tick for me & a really good find for the Gann
