I sympathise with your parrot problem. We lost nearly all our crop (again, a young grove, so we didn't expect much) to Ring neck parrots. We have large areas of National Park nearby, and it isn't uncommon to see flocks of 20 or 30 parrots swooping in and out of the trees. Their usual food source was depleted this year, but now they have discovered olives I'm sure they'll keep eating them. They first attack the fruit in January, when the pit is hardening - just slice them in half and take out the pit, then later nibble on them constantly, as they ripen. I have placed a parrot trap in our grove. It functions like a lobster pot ( they can get in but can't get out), baited with a handful of wheat, and is the size of the back of a ute. You can stand up in it. I have a licence from the State Department of Conservation and Land Management to use this trap, and there are strict rules about its operation and reporting. I have been assured shooting is more effective, but I don't shoot, and in any case the neighbours would complain. I have disposed of over thirty parrots in about a month. The man who built the trap assures me I will see the benefits in a couple of years, but you have to keep it going constantly. I hate killing these beautiful birds, but it is war.
