U.S. bird species declining - ENN

"More than one in four U.S. bird species is declining in numbers or at risk of disappearing, according to a new report from the National Audubon Society.

"The birds' conditions, worrisome on their own, should be taken as a broader indication of the health of the country's ecosystem, despite successes such as the recoveries of the bald eagle and peregrine falcon, the group said."
