The National Audubon Society released a report this past Tuesday, September 9, indicating that 314 North American Bird species are on the brink, due to shifting and shrinking ranges that have a fundamental cause in climate change. This includes loss of habitat caused by a number of factors including climate shifts and commodification of natural resources such as forests. 126 species are identified in the report that will lose more than 50% of their current ranges, some up to 100% by 2050. Another 188 species face catastrophic loss of range by 2080. The Bald Eagle is expected to loose 73% of its range by 2080. Familiar birds like the Baltimore Oriole, Common Loon, the Purple Finch, and the Wood Thrush may will be significantly effected. Some like the Trumpeter Swan will not survive.

The Baltimore oriole will probably no longer live in Maryland, the common loon might leave Minnesota, and the trumpeter swan could be entirely gone.
Those are some of the grim prospects outlined in a report released on Monday by the National Audubon Society, which found that climate change is likely to so alter the bird population of North America that about half of the approximately 650 species will be driven to smaller spaces or forced to find new places to live, feed and breed over the next 65 years. If they do not — and for several dozen it will be very difficult — they could become extinct.
The four Audubon Society scientists who wrote the report projected in it that 21.4 percent of existing bird species studied will lose “more than half of the current climactic range by 2050 without the potential to make up losses by moving to other areas.” An additional 32 percent will be in the same predicament by 2080, they said.
