Couldnt believe my luck when after finishing my last nightshift and having 3 hours kip that the Mega alert went off on the pager... Greater Yellowlegs and only an hour and twenty minutes away. I was off. Views were distant and through the camera only posed as record shots. Someone did mention Greenshank but there were no other debates as too anything but the wanted bird, I certainly did not have any knowledge about Greater's but the legs stood out for sure. Sadly it was not to be, as quoted in BWP by Snow & Perrins: "[Serious confusion likely only with the latter(Greater Yellowlegs),but even if particular individual of Greenshank is one of the rare yellow-legged type,]"
I'll leave it at that, sounds more wishful than chasing after just a Greenshank.
