Sorry, quite long ...
I grew up on Eyre Peninsula and still have a house in a coastal town on EP that I visit regularly.
I have concerns about how our State departments have handled the survival of these cockatoos ... even before the bushfires and the drought.
You see, for years the birds have used non-native Aleppo pines as a food source. There has been a push in recent years to eradicate Eyre Peninsula of the pine trees because they are a declared pest, yet the gums the cockatoos prefer were gradually reducing because of bushland being cleared to create more space for cropping.
The cockatoos, it seems, are the only ones to suffer from the removal of the trees, which were originally planted as wind-breaks but really did spread quite badly. Nothing likes to grow beneath an Aleppo and if it wasn't for the birds I would agree with their eradication.
Several years ago my mother went to the local newspaper (at which I used to work) in an attempt to raise awareness about the need to look at the impact of removing the Aleppos, but the reaction was pretty much that she was a batty older lady who didn't know what she was on about.
On a positive note, I recall a school group providing nest boxes as a substitute for the nesting hollows that were destroyed by the fires.
On another subject, I found a photo I took a couple of years ago of a flock of major mitchell cockatoos taking a drink at an old farm trough. It's not the best, but some members might like to look at it if I can remember how to post pics.
