A group of American Wigeons coming in for a landing at the Village Creek Drying Beds in Fort Worth, Texas.
Wikipedia has this to say about American Wigeons:
The American Wigeon is a medium-sized bird; it is larger than a teal, but smaller than a pintail. In silhouette, the wigeon can be distinguished from other dabblers by its round head, short neck, and small bill. It is 42–59 cm (17–23 in) long, with a 76–91 cm (30–36 in) wingspan and a weight of 512–1,330 g (1.13–2.9 lb). This wigeon has two adult molts per year and a juvenile molt in the first year, as well.
