Parrot population data and a question for birding aus members

[Sonja Ross <>]

Hi Don,

One reason in Victoria is that September and October tend to be our wettest
months so birders may possibly spend less time out birding.   It could also
be that if the birds are breeding in our spring, at least for part of the
time, one of a pair could be sitting one eggs.

Another could be that April is often Easter when people are often out
camping and birding.  Successful breeding would also show up in increased
numbers then before winter.
