I came across this 1st winter Green-winged Teal type thing while sifting through the large flock of Teal. Unfortunately the Teal were extremely distant and not helped by the fact that i had left my zoom eye piece in the car. This bird still had some juvenile Scaps and flank feathers but to my eyes the white vertical stripe just didn't look strong enough. It was possible that a few juv feathers were still concealing some of the white but i wasn't convined it would get much thicker. Closer views and maybe another 2 weeks would have helped.
