This morning I was peacefully eating my breakfast when this horrendous screetching interrupted me. I knew the cocatoos were around & by the sound,there were lots of them. The noise continued, fading in & out, until it seemed to settle into one spot, extremely loud. They could only be in one spot, the gum tree in my neighbours yard. I have captured about a dozen here, but there were others in other parts of the tree. Thank goodness they only stayed settled for about 5 minutes, before moving on to disrupt someone else's breakfast, and I could continue with mine.
