One night they told us we'd have an early morning bird watch. They had parked the boat nosed into some reeds. At the 5am wakeup call we went up to the top and there was a raucus noise of birds in the reeds although none could be seen. As it got a bit later some birds started flying around and gradually there were more and more. White parakeets and various parrots. At several points the sky became full of flying birds.
