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.
Male Brown-capped Rosy-Finches are indeed brown and rosy, but with a blackish cap, making this species’ name potentially confusing. It currently has a tiny range, breeding only on alpine tundra from southern Wyoming to southern Colorado, and wintering in the surrounding foothills, including in northernmost New Mexico. The pressures it faces are immense: a warming climate will force breeding habitat (alpine tundra) up in elevation. Since the habitat is now restricted to just the very tops of mountains, it will likely disappear completely. Winter habitat (high-elevation forests) is also projected to contract. By 2080, Audubon's climate model predicts that only three percent of the current winter range will have a similar climate to today.
