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.
A migratory species, the Eared Grebe nests in interior marshes of the western US and southwestern Canada. It winters widely in the southwestern U.S. and in Mexico. Although it doesn’t shun saltwater, it does prefer inland lakes. Audubon’s climate model predicts a bleak future of the species in North America, with its summer range completely shifting and contracting by essentially 100%. Thankfully, the species also lives in the Old World (where it is called Black-necked Grebe) and in central Mexico. One hopes that those breeding populations fare better than is projected for the ones in the U.S. and Canada.
