Janet Gardner, an Australian National University biologist, led a team of scientists who measured museum specimens to plot the decline in size of eight species of Australian birds over the past century.
The research, published last week in the British journal Proceedings of the Royal Society B: Biological Sciences, found the birds in Australia’s southeast had become between 2 per cent to 4 per cent smaller.
Over the same century, Australia’s average daily temperature rose 1.3 degrees Fahrenheit (0.7 deg C), with the sharpest increase since the 1950s.
