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.
Jaegers—including the dashing, acrobatic Parasitic—inhabit two realms particularly susceptible to the effects of climate change: the Arctic in summer and open oceans in winter. Today Parasitic Jaegers nest across a broad swath of dry, often rocky and hilly, tundra in North America and Eurasia, but Audubon's climate model forecasts a sizable loss of about one-third of areas with suitable climate in summer. Areas with suitable climate for wintering birds are forecast to decline more sharply. However, that dire prediction is tempered somewhat by the fact that most of the Parasitic Jaeger’s offshore wintering grounds lie outside U.S. waters.
