Researchers with Ducks Unlimited Great Plains Region have been hard at work this summer, nest dragging on the 2,500 acre research ranch in North Dakota. They have discovered over 150 nests for a variety of waterfowl species, including Mallards, Blue-Winged Teal and Gadwalls. Recently, there were two successful hatches of Blue-winged Teal on camera. There are many more nests that will be hatching soon.
