Climate change possible cause of bird species decline

LAS VEGAS — Climate change could be to blame for the collapse of bird populations in the desert along the Nevada-California border, scientists said.

The number of bird species has fallen by an average of 43 per cent over the past century at survey sites across an area larger than New York state, according to a new study by researchers at the University of California, Berkeley.

Science Says: Hotter weather turbocharges US West wildfires
