Audubon Report: Global Warming Threatens Half Of North America’s Bird Species

As the world gets warmer, the Baltimore oriole will no longer be found in Maryland. The Mississippi kite will move north, east and almost out of its namesake state. And the California gull will be found less often in the Golden State.

Those are among the conclusions in a National Audubon Society report that looks at the potential effects of global warming on birds by the year 2080.

Over the next six decades or so, the critical ranges of more than half the 588 North American bird species will either shrink significantly or move into uncharted territory for the animal, the report states.
