WASHINGTON - From grasslands to seashores to forests and backyards, birds are disappearing at an alarming rate in the United States and Canada, with a 29% population drop since 1970 and a net loss of about 2.9 billion birds, scientists said on Thursday.
“The take-home message is that our findings add to mounting evidence with other recent studies showing massive declines in insects, amphibians and other taxa, signaling a widespread ecological crisis,” Marra added. “Birds are the quintessential indicators of environmental health, the canaries in the coal mine, and they’re telling us it’s urgent to take action to ensure our planet can continue to sustain wildlife and people.
The researchers tracked populations of 529 species using decades of bird counts taken on the ground as well as weather radar data that revealed similar declines in the volume of migratory birds. The researchers documented a steep decline for migratory birds. They noted broad declines among birds that migrate to the tropics, where there have been devastating rates of habitat loss and degradation. Migrating birds also face threats at their stopover sites and on their North American breeding grounds.
