"A quarter of all bird species in the United States have declined in population since the 1970s, according to a report issued by the National Audubon Society.Of more than 800 native U.S. bird species, 201 are included on the group's Watchlist 2000...the decline or loss of bird and other species occurs in relation to major ecological changes that have potentially broader implications.Bird populations, reproductive rates, and behavior change in response to conditions that also affect the quality of life for people and other wildlife, such as habitat degradation, poor water quality, and depleted fisheries."
