In a not so surprising story, the habitat for birds continues to dwindle as man encroaches more on the natural environment.
According to recent testimony to U.S. Congress by scientists, government officials and conservation groups, 20 common bird species have lost 68 percent of their populations in the past 40 years.
“A growing proportion of the landscape is occupied by humans,” said Wayne Thogmartin, a scientist at the U.S. Geological Survey, which measures bird populations. “A large part is irrevocably lost to birds. The question is what populations do we want to keep. If we want more, we need to find ways to create habitat.”
