side by side comparison
Identification of female type Green-winged Teal has been a little pet interest of mine for a while. Have even written about it a few times elsewhere. Here then a nice refresher and update from Slimbridge WWT warden, James Lees, comparing adult females of captive Green-winged Teals and Eurasian Teal, side by side: Can you see all the little, but helpful differences? YES you can identify them in the field!
Great job James, ta very much. All photos copyright James Lees at Slimbridge WWT, Feb 2012
