Janet mentioned that black coackatoos flocking might be a
precursor indication of rain. Which set me thinking. Does anyone
else know of incidents (either fact or fable) where birds, by their activities
or behaviour, seem to provide an advance indication/foreknowledge of coming
physical events - rain, thunderstorms, earthquakes, flood, locqust plague,
etc, in advance of any indications being obvious to humans?
And of course, there is the ongoing problem of 'how do
the waterbirds know that Lake Eyre has been filled'.
