These parakeets are newcomers this year. I heard and spotted one about a week ago on two separate occasions as it flew and across the rooftops. Now there's a flock of at least six or more. Pairs of them were flying around in circles, level at tree top height, squawking and back onto the tree. They have a raucous, cackling cry, which I never heard before and is not at all melodious. A magnificent sight when they are flying!
