Two negatives make a positive so not Not A Knot makes it a Knot.
At WH tonight, an odd looking wader, along with the usual suspects. I thought it might be a Knot, but in Temminck's-like fashion, poop, scoop, home, Collin's, scope, car, run, view.
It was a Knot, in winter plumage, and confirmed by local wise man Lindsey McDougall, who was equally intrigued. A good bird for the patch, and plenty of Barn Owl action too.
