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!
