A new study from researchers at The Australian National University (ANU) rolls back the curtain on half a century of evidence detailing the impact of climate change on more than 60 different bird species.
It found that half of all changes to key physical and behavioural bird characteristics since the 1960s can be linked to climate change.
The other 50 per cent is due to other unknown environmental factors that have changed at the same time as our climate.
The research, published in the Proceedings of the National Academy of Sciences and carried out in conjunction with James Cook University (JCU), focused on birds in the United Kingdom and the Netherlands.
"We have shown that climate change is a major driver of these changes in the birds, but there is more at play here than we originally thought," lead author Dr Nina McLean, from the ANU Research School of Biology, said.
