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.
Until recently, the Dusky and Sooty grouse were considered one species, the Blue Grouse. Broadly speaking, they are large, grayish grouse found in wooded, often mountainous areas, but they differ substantially in, plumage, behavior, and habitat preference. For instance, Dusky Grouse can be found in wet, dense forests at sea level, while Sooty Grouse may be found in sagebrush with scattered trees. Both species are notoriously hard to detect, making them underreported in many data sets. Audubon’s climate model predicts a 60 percent loss of current winter range by 2080, a very troubling statistic even for these notoriously furtive species.
