US Bird Count Shows Climate Change Affecting Migration Patterns

Thousands of birdwatchers in the United States, Canada, Latin America and the Caribbean were out in force from mid-December to the beginning of January (December 14-January 5) counting birds. They took part in the 115th “Christmas Bird Count,” sponsored by the National Audubon Society, a U.S. bird conservation organization. Data collected from the annual event is helping scientists understand how environmental changes affect birds. VOA’s Deborah Block joined a group of birdwatchers in the wetlands at Mount Vernon, Virginia -the famous home of the first U.S. president, George Washington.
