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 Zone-tailed Hawk is named for the white bands that partition the tail into different “zones.” In North America, it is mainly a migratory species, with most individuals vacating the U.S. to winter in Middle America. While Audubon's climate model doesn’t tell us anything about future breeding conditions, it does show a 100 percent loss of current winter range by 2080. The species is a widespread resident in South America, so it remains to be seen if more southern birds will move in to replace the potentially lost range.
