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.
Look out over a northern meadow in June and you may see a black-and-white bird fluttering over the grasses, singing a bizarre but cheerful jumble of clicks, buzzes, and trills: the song of a Bobolink. Though Audubon's climate model projects this species ideal climate space may increase by more than half, only one-fifth of the species’ current range will remain stable, and the map clearly shows this with the range shifting noticeably to the north. Fortunately, this grassland species is well adapted to seeking out and colonizing new areas. If grasslands can develop in the new climatically suitable areas, the Bobolink may be able to ride the wave of northward shifting climate space.
