In going through some old photos, I have a photo which was taken at Northview Golf Course, Vancouver, B.C. in May 2008. I had noted it as a Mallard, which is totally wrong, but not sure if it is a Green-winged Teal. Could someone kindly confirm this? Doesn't look exactly like the one in my Sibley ap. as the colour on the wing looks blue in the photo . Thanks in advance!
