the early bird

Australia’s migratory birds are arriving earlier and leaving later and global warming is likely to be a reason, a study has found.

Macquarie University PhD students Linda Beaumont and Ian McAllan and Associate Professor Lesley Hughes have analysed the movements of migratory birds visiting south-eastern Australia since the 1960s.

They have compared the arrival of 34 species and the departure of 12 species over the past 40 years.

Temperature change in Australia of about 0.5 degrees since the 1960s was very likely to influence migratory patterns, Ms Beaumont said.
