ON THE ROAD — The Pied Butcherbird (Cracticus nigrogularis) is renowned for its complex and mellifluous song. But at the Olive Pink Botanical Garden in Alice Springs, with the temperature heading towards 40 degrees centigrade mid-morning, the adult bird was gaping her beak only to cool down. Her youngster, wearing immature plumage which includes the superb brown and black bib, was coping a little better with the heat.
