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.
Hardy and adaptable, the Greater Yellowlegs has been showing up on recent years’ Christmas Bird Counts with increasing frequency, especially well inland in the southern U.S.—a trend that may accelerate in the decades ahead. Audubon’s climate model forecasts areas with suitable climate to more than double in extent in winter, with the species wintering north well into the Midwest and Great Lakes region. However in the summer season, trouble appears ahead, as only 19% of the current range is predicted to be climate stable. As will affect other boreal breeders, a key consideration for the future will be forest health—a matter of considerable concern.
