The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
At first glance, a male Gadwall is a rather dull bird, but look closely and you’ll see incredibly intricate patterns of black, gray, and white. Audubon's climate model’s future projection for the Gadwall is similarly dual in nature. While its winter range is projected to be largely stable and potentially increasing (by 27 percent), 91 percent of the species’ summer range is projected to disappear. The total amount of available space is projected to atrophy by a potentially catastrophic 87 percent. If there’s any hope for the Gadwall, it’s that this is a numerous and widespread species, with many thousands (if not millions) also living in the Old World.
