Bowerbird

Bowerbird: Any of 17 bird species that constitute the family Ptilonorhynchidae of the order Passeriformes. Bowerbirds are birds of Australia, New Guinea, and nearby islands that build more or less elaborate structures on the ground. Some are called catbirds, gardeners, and stagemakers. The male builds the bower, and he displays and sings loudly in or above it; females visit him there and lay their eggs in simple nests some distance away. The bowers, beset with all kinds of shiny and coloured objects, are of three kinds. The “mat,” or “platform type,". ...the “maypole” type, which consists of a tower of twigs erected around one or more saplings in a cleared court, and... ...the “avenue” type consisting of two close-set parallel walls of sticks, interwoven and sometimes overarching, on a circular mat of twigs. Avenues are made by the satin bowerbird ; the regent bowerbird and its relatives; and the spotted bowerbird and its relatives. Satin and regent bowerbirds make a paint of vegetable pulp, charcoal, and saliva and apply it to the interior walls; a daub of green leaves may be used—a rare instance of a bird using a tool.
