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.
Most alcids breed in dense colonies near the sea, but not this one. Kittlitz’s Murrelets nest in isolated pairs at high elevations well inland in Alaska and Siberia. Not surprisingly, the species is little known. But what we do know is distressing, as the species is in sharp, possibly catastrophic, decline. Audubon's climate model, focusing on climatic conditions in winter, forecasts additional trouble: an almost complete loss of the current range. Melting glaciers, warming seas, and increased disturbances from extractive industries are among the challenges this murrelet faces.
