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.
There are currently only about 350 Whooping Cranes in the wild today, making it one of the most endangered birds on the continent. But that’s a vast improvement: in 1941 there were only 21. Audubon's climate model projects an 85 percent loss of current winter range by 2080, possibly making conditions at their primary wintering location, Aransas National Wildlife Refuge in Texas, less amenable to the species. With just this one main wintering location, a single hurricane might deal a fatal blow to the entire species. Breeding sites in Canada and Idaho were not captured by the model and thus no summer result was produced.
