Nearly three-quarters of all bird species in north-east Australia and more than a third in Europe could become extinct unless efforts to stop global warming are stepped up, a report said yesterday.
The World Wildlife Fund report said bird groups, such as seabirds and migratory birds, were very sensitive to climate change.
"Large-scale bird extinctions may occur sooner than we thought," WWF's director of climate change policy Hans Verolme said in the report.
"If high rates of extinction are to be avoided, rapid and significant cuts to greenhouse gas emissions must be made," the WWF said.
Rising sea levels, changes in vegetation and altered temperatures are among the effects of climate change linked to greenhouse gas emissions that impact negatively on bird species worldwide, it said.
