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.
Birds with “Boreal” in their name should set off alarm bells in any discussion of climate change, as the boreal forest is one of the biomes believed to be at greatest risk from warming temperatures and disrupted precipitation regimes. Audubon's climate model predicts that this forest owl, a quintessential inhabitant of spruce–fir forests across the northern hemisphere, will suffer major losses in the face of climate change. Boreal Owls in the southern portions of the species’ range—extending south to New Mexico—may disappear altogether. Their forest domains, already deteriorating from fire suppression and insect outbreaks, may be nearly wiped out by climate change.
