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.
Although locally common in oak scrublands, the Black-capped Vireo is a Federally-listed Endangered species. Its favored habitat is under siege from a host of threats: overgrazing, “weed” control, fire suppression, development, and brood parasitism by cowbirds. Audubon’s climate model shows huge growth—by 300+ percent—of suitable climate space for this vireo, but that result will likely not translate into an actual range expansion. Since the bulk of suitable climate space predicted by the model is centered in California coast, far from where the species occurs, it would be virtually impossible for this vireo to colonize that area. Of particular concern is that only 5 percent of currently suitable climate space for the Black-capped Vireo is considered by the model to be stable.
