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.
The Blue-winged Teal, unlike many other migratory waterfowl, is much less adapted to withstanding cold temperatures, and most winter in Mexico and Central America. Audubon’s climate model projects a significant shift in summer range by 2080, with only 39% of the present remaining stable and nearly completely away from the current core of its range. As with many other species, the summer climate space of this elegant little duck will likely move northward. While the suitable areas for wintering in the United States may increase, it remains to be seen if this species will be able to follows the shifting climate suitable areas in the summer.
