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.
Strictly coastal species like the Black Skimmer are risk-takers. Coastal storms can wipe out large chunks of any particular region’s population, and the direct and indirect effects of human activity have been largely negative. Audubon's climate model introduces additional challenges for this striking and already beleaguered denizen of barrier beaches and back bays. Climatically suitable areas are forecast to decline by nearly two-thirds in winter. Add to that the specter of rising sea levels, and the Black Skimmer’s best hope may be a range shift inland—a possible outcome according to the model.
