Read this and the next two entries to see how Northern Shoveler (above photo) is a teal, very closely related to Blue-winged Teal and Cinnamon Teal. The bright blue leading edge of the inner wing is only visible on the lower male duck on the right side of the photo. Compare with the wings of Blue-winged Teal and Cinnamon Teal in the following two posts to see how they have the same wing pattern and are closely related.
