After failing to locate the Blue-winged Teal- lifer, at Castle Island during our WEBS count on Sunday morning I went back on Monday afternoon.
A large gathering of Ruff were on the mud under Stakeford Bridge on both days accompanied by 2 late Common Sandpiper on Sunday and a Spotted Redshank on Monday. Two Greenshank and another Common Sandpiper were further up river past Castle Island on Sunday and were replaced by three Little Egret on Monday. I saw a Little Egret in the same place on both days, on the Sleekburn at low tide.
Groups of Teal were scattered across the river and after scanning them all with no luck I got a text from Birding Sometimes saying it was coming down river towards the rowing club. As I looked across I could see it swimming near to the bank albeit distantly. By the time I got around to the other side of the river I saw it fly off back to where I had been. At least I was able to appreciate its name as it flew low over the river.
To my untrained eye I see nothing wrong with it and would like to hear an explanation as to why it is being touted as a hybrid. I'll leave that one to the experts.
