Idaho Birds 'On the Brink' In Dire Audubon Society Report

Posted By on Sun, Oct 5, 2014 at 11:23 AM



A first-of-its-kind study from the Audubon Society forecasts a stunning impact of climate change on North American birds. 

According to the report, nearly 40 species that are common to Idaho are expected to be all but devastated by the change.

The Audubon Society studied 588 North American bird species and more than half are likely to be in trouble. Scientists used three decades of observations to define "climatic suitability" for each species—the range of temperatures, precipitation and seasonal changes each species needs to survive—and then laid that information atop internationally-recognized greenhouse gas emissions scenarios.

Idaho is part of the so-called "central flyway," running from the Arctic Ocean to the Gulf of Mexico and, in particular, the survey predicts that 11 species that fly through the Gem State will lose between 90-100 percent of their summer range due to climate change, including:

- Trumpeter Swans, 100 percent of summer range lost
- Bohemian Waxwing, 100 percent lost
- Merlin, 98 percent
- California Gull, 98 percent
- Evening Grosbeak, 98 percent
- Barrow's Goldeneye, 97 percent
- Ring-necked Duck, 93 percent
- Gadwall, 92 percent
- Hooded Merganser, 92 percent
- Townsend's Solitaire, 92 percent
- Prairie Falcon, 90 percent
