The Sharp-tailed Grouse is the smaller and more forest-dwelling cousin of the two prairie-chickens. Audubon’s climate model projects a range shift and significant decrease in available summer area of climate space. Much of the model’s remaining summer available area, however, is within the current range of the species, so the 76 percent loss in summer range is of considerable concern. The species’ winter range appears is also predicted to shift, with under half remaining stable through 2080.
The colors indicate the season in which the bird may find suitable conditions-- blue for winter, yellow for summer (breeding), and green for where they overlap (indicating their presence year-round). The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there.
The outline of the approximate current range for each season remains fixed in each frame, allowing you to compare how the range will expand, contract, or shift in the future. The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000).
The next three frames predict where this bird's suitable climate may shift in the future--one frame each for 2020, 2050, and 2080.
