Orioles, eagles, partridges and seagulls are among the 389 types of birds – 64% of the 604 species evaluated on this continent – that are highly or moderately vulnerable to Climate Change, says the study.
The existential threat to birds also affects humanity. While the Canaries warned coal miners of invisible death in the industrial age, birds of all shapes and sizes can now be warning of life and death in the age of global warming.
But if humanity can somehow escape the proverbial coal mine in time and maintain the 1.5 degree Celsius target in the Paris Accord, 76 percent of the most vulnerable species must survive, the Audubon study says.
"Our findings in this report are the fifth alarm in a five-alarm fire," says David O'Neill, Audubon Chief Conservation Officer, at study called Degree Survival: 389 species of birds on the edge.
He called for immediate action to slow the warming of the planet to save birds and more.
"It's a combination of changes in temperature, rainfall and vegetation," says Brooke Bateman, senior climate scientist at Audubon. "And birds will have to move and change to keep up with these changes. And in addition, we also have the pressure of changes in sea level rise, urbanization, extreme weather events that will affect these changes." species no matter where they go. "
Formed in 1905, when the demand for feathered hats nearly drove Florida waders to extinction, the National Audubon Society is one of the oldest conservation groups in the world. And thanks to the obsessive record keeping of devout observers, Audubon scientists were able to extract from a database of 140 million bird study records in Mexico, the US and Canada.
Using the latest climate models from the Intergovernmental Panel on Climate Change, they examined the habitats of 604 North American species. Given projected increases in drought, heat, fire, rain and other factors, they found that 389 of the species studied would probably not survive in a warmer 3 degrees world.
Bateman was in second grade when he first heard the haunting of the common loon on a lake in Wisconsin. This was her "spark bird" that awakened her to a "wonderful and wonderful world of birds".
"Last year I brought my 5 year old daughter and she heard the loon for the first time. And it's like magic, you see it on their faces."
But as a vivid example of what science calls the "baseline shift syndrome," the daughter of the daughter may never have the same experience.
"The (loon) track will completely shift out of the US with climate change," says Bateman. "Then you will no longer be able to go to the same place and hear the bird call anymore."
And more alarming than the loss of music and flashes of color in the backyard feeder is what birds like the American robin tell us about the speed of change.
"In fact, robins are hibernating in many places more often than they used to and won't go away," says Bateman.
And at the risk of exhausting the analogy, she says that every time you see a robin in December, think of that canary in the coal mine.
"Birds are tellers. Birds tell us. They are the ones telling us what is going on in the environment. And so, we tell Audubon that the birds are telling us that it is time to act."
