Kookaburra. The Laughing Kookaburra at 45cm is the largest of Australian kingfishers and the best known with a famous raucous accelerating, rollicking laugh, one of the best known sounds of the Australian countryside. The call is begun by one bird, others joining in until the full laugh is taken up by all. It has a massive bill, black above and horn-coloured below. It lives in family groups in forest edges and clearings, savannah woodlands and frequently around country towns and dwellings and some metropolian gardens.
