Hi all,
some very annoying but interesting behaviour from our local sulphur
crested cockatoos recently. In Helensburgh (NSW) they have learnt how
to open the lids of our garbage bins (otto or wheely bins) and scatter
rubbish everywhere as they rummage through them. So to prevent this I
looped a chain through he lid handles, great I thought they can't lift
that and it kept them out for a week or so. Then one afternoon I came
home to find they had spent the day neatly chopping off one of the
handles cutting it through right where it joins the lid and the chain
dangling.
They still couldn't open it though and as of about 5 days have not
returned. Seems to me it shows some level of intelligence to work out
if they removed the handle they could remove the chain. Wondering
though if it might also be evidence they can't count, that is they did
it once, no result so no point doing it again, but without knowing there
are two handles to deal with?
The bloodwoods (I think a corymbia sp in any case) are in heavy flower
around here and the Royal NP right now, so as usual the cockatoos spend
time in the trees snipping off the inflorescences and dropping them to
the ground otherwise untouched, they don't seem to eat anything just
chew them off and drop them to the ground. Often wondered what's in for
them to spend so much time snipping away.
regards,
Chris Ross
