I recently watched these cockatoos at Collier Park Golf Course making a mess of the fairways with their feeding efforts and doing gymnastic exercises with a hole marker flag.
The satellite tracking devices have shown that at least two of my study birds have been roosting at night in the pines around Collier Park Golf Course, Curtin University and Technology Park. I was hoping to spot them amongst the flocks feeding and drinking at the golf course. No luck this time though.
