Drop in migratory bird numbers: study

AM - Drop in migratory bird numbers: study
Quote:
Like the frog, birds are considered an accurate barometer of the state of the environment.
Fewer migratory birds is a cause for concern.
A new study has found Australia's massive migratory bird population has plummeted over the last 25 years with up to 75 per cent disappearing.
It's the first major long-term survey assessing the shore birds from Broome to Sydney.
