North America has lost nearly 3 billion birds since 1970, a study said Thursday, which also found significant population declines among hundreds of bird species, including those once considered plentiful.
"Multiple, independent lines of evidence show a massive reduction in the abundance of birds," said study lead author Ken Rosenberg, a senior scientist at the Cornell Lab of Ornithology and American Bird Conservancy, in a statement."We expected to see continuing declines of threatened species. But for the first time, the results also showed pervasive losses among common birds across all habitats, including backyard birds.
Other threats to birds include deaths because of free-roaming cats, collisions with glass, toxic pesticides and insect decline. Climate change compounds all of these problems and also accelerates the loss of the habitats that birds need, experts say.
