The Kookaburra of Australia and New Guinea is one of the world's largest Kingfishers. He is noted for his raucous laughing call, which rings out with frenzied excitement as he marks the boundaries of his territory. Families tend to stay together, the young from previous broods helping to defend their home range from intruders. His habitat is versatile, and he is as likely to be found in forest, arid grasslands or urban parks. He follows a carnivorous diet, and will eat almost anything he can gobble up - from lizards, rodents, baby birds, and he is may steal koi fish from zoos and ornamental pools.
