Nearly two-thirds of North American birds studied will go extinct if global warming hits 3 degrees Celsius (5.4˚F), a new report from the National Audubon Society finds.
Orioles, eagles, grouse and gulls are among 389 types of bird -- 64% of 604 species assessed on this continent -- that are highly or moderately vulnerable to climate change, the study says.
The stark warning follows research published last month that showed the US and Canada had lost 2.9 billion birds in about the last 50 years.
The existential threat to birds also impacts humanity. As canaries warned coalminers of invisible death in the industrial era, now birds of every shape and size can be life-or-death alerts in the age of global warming.
