smaller babblers and warblers

Australian birds are getting smaller and global warming is probably to blame, new research suggests.

Chief researcher Janet Gardner, from the ANU’s research school of biology, said the results reflected that animals tended to be smaller in warmer climates.

Dr Gardner said the extent of change in the south-eastern Australian species examined, including the grey-crowned babbler, hooded robin and speckled warbler, was surprising.
