We have had lots of cockies at our house over the summer with the biggest flock being almost 50 birds. They ate all of our almonds but despite often being caught in the walnut tree we still ended up with a bumper crop which more than filled a big recycling crate with good quality walnuts. The cockies are still around in smaller numbers and Sofia is determined that they go, even though they are now just munching on the grevillea in the front yard.
Last weekend she was up on a chair in the sunroom telling them as loud as she could to "Go away cockies".
We even went outside on the verandah but they still didn't seem that bothered.
