I was lucky on February 18th to find a Common Teal which is the Eurasian form of Green-winged Teal. It was the second time in two years I found one at Brookville Park in southeast Queens NY. This was even an earlier date than last years find, which was on March 1st. You can find last year's post here which details some of the nuances in separating Eurasian from American Green-winged Teal. Below are a couple of photos showing both forms.
