Hi Warren
I expect birds will still be being poisoned in the way you describe. The
anti-corella and galah feeling around Wilmington in SA where I live is high.
People don't seem to like any other living thing which disturbs them in
some way. Only a few years ago(not sure what is happening now) corellas and
galahs were being poisoned around silos in SA.
in terms of mice poison killing birds and your question about why are they
going for dead mice when there are plenty of live mice to get, maybe they
are eating the mice while they are still moving. I have seen mice running
and haemorrhaging at the same time back when I use to use the poison.
Around our house i see grey backed butcherbird and magpies eating mice.
