The Bald Eagle, the Common Loon, Baltimore Oriole and Brown Pelican are just a few of the 326 North American bird species identified by researchers as threatened by climate change.

The study by Audubon Society Chief Scientist Gary Langham and his colleagues examines 30 years of climate data and tens of thousands of bird observations from across North America to find links between population trends and climate conditions. Those trends are further extrapolated to predict the future of individual species.

Some bird species will be able to adapt to changing conditions, find new habitats or adapt to alternate habitats. However, according to the researchers findings 126 species of birds will lose 50 to 100 percent of their current habitat by 2050 and an additional 188 species will lose 50 percent or more of their habitat by 2080.

“It’s a punch in the gut. The greatest threat our birds face today is global warming. That’s our unequivocal conclusion after seven years of painstakingly careful and thorough research. Global warming threatens the basic fabric of life on which birds – and the rest of us – depend, and we have to act quickly and decisively if we are going to avoid catastrophe for them and for us,” said Langham in a statement.

The team behind the report, funded in part by the US Fish and Wildlife Service, hopes that their findings will enable scientists, conservationists, land managers and policy makers to take steps to help protect threatened species.

“Millions of people across the country will take this threat personally because birds matter to them. For bird lovers, this issue transcends nasty political posturing; it’s a bird issue. And we know that when we do the right things for birds, we do the right things for people too. Everyone can do something, from changing the plants in their backyard to working at the community and state level to protect the places birds will need to survive and promote clean energy. We are what hope looks like to a bird,” said Audubon President and CEO David Yarnold.

In conjunction with the report, the Audubon society has created a web portal that includes maps, photographs, technical reports and in-depth stories on the bird species in jeopardy.
