Audubon: Common backyard birds disappearing
Some of the most common birds seen and heard in American back yards are becoming a less frequent sight and sound in much of the United States, according to a study released by the National Audubon Society.
Oman&#39;s Arabian Oryx sanctuary this week  became the first site to be removed from UNESCO&#39;s World  Heritage list after the rare species dwindled and the  government cut the park size by 90 percent.
