This photo was sent to us by Jane and Michel DeRidder, with the caption:
This delightful circle was taken at Lamington national park, west of the Gold Coast. These are native Australian mountain parrots, the red and blue kind are crimson rosella and the red and green are King Parrots. They are feasting on sunflower seed which Mr. Watt had left for them, but did not expect them to form such a perfect ring. This guy on the bottom is about to jump into the centre, to the discontent of the other birds.
