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.
Formerly persecuted for being so predatory, the Merlin has staged a remarkable recovery in recent years. Counts have increased at many, but not all, migration monitoring stages, and numbers have generally risen in winter. But the truly dramatic story has been on the breeding grounds, as the species has rapidly spread southward in Canada, the Great Lakes region, and the northeastern U.S. Audubon's climate model projects a reversal of these recent gains, showing a dramatic loss of 97 percent of its current summer range. One thing the Merlin may have going for it—even in the face of climate change—is its recent successes in suburban and urban districts.
