The Bowerbirds Ptilonorhynchidae

The bowerbirds are unique in the avian world in that the males build elaborate 'bowers': structures of sticks, grasses or other plant stems on or close to the ground, often incorporating objects such as colourful fruits, flowers, feathers, bones, stones, shells, insect skeletons, and numerous other natural (and human-made) objects. The highly sophisticated building, decorating, arranging, singing, and courtship posturing and dancing by males is primarily to attract and impress females. As much of it is performed in the absence of females, however, some consider it possible that males may also enjoy such activities for their own sake. The bowers and the birds' behaviour associated with them have been much studied by behavioral ecologists searching for evolutionary and ecological explanations of behavioural patterns. The Bowerbirds is an indispensable work of reference for everyone interested in these birds.

Clifford Frith is the author of a highly-respected companion volume in the Bird Families of the World series, The Birds of Paradise. Clifford's early ornithological positions included The Natural History Museum, London, and the Royal Society of London Research Station, Aldabra Atoll, Indian Ocean. He obtained his PhD at Griffith University, Brisbane, for evolutionary studies of bowerbirds and birds of paradise. Dawn Frith obtained her PhD, in littoral zone marine biology, at London University and lectured in zoology before meeting Clifford on Aldabra Atoll, where she studied insects. Both Cliff and Dawn are private ornithologists and self-employed natural history authors, photographers, and publishers. They have worked on tropical Australasian birds, as well as various other avian, other vertebrate, and invertebrate, groups, and mangrove ecology, in the Indian Ocean, Southeast Asia, and tropical Pacific. They are Honorary Research Fellows of the Queensland Museum and joint recipients of the Royal Australasian Ornithologists' Union's D. L. Serventy Medal for contributions to ornithology.
