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.
This bird’s natural history is completely constrained by the availability of free-flowing streams and rivers. Sightings even a few feet away from rushing water are notable. American Dippers occur in winter as far upstream as there is open water; downstream, they don’t like the water too warm. Audubon's climate model forecasts a dynamic climate future for the dipper, with only 12% of its current summer climate space remaining available by 2080. Smaller shifts will likely take place in this species’ winter climate space as well, but the summer season may drive its future.
