The willie wagtail (Rhipidura leucophrys) is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and eastern Indonesia. It measures about 19–21.5 cm (7+1⁄2–8+1⁄2 in) in length. The willie wagtail is insectivorous and spends much time chasing prey in open habitat. Its common name is derived from its habit of wagging its tail horizontally when foraging on the ground. Aggressive and territorial, the willie wagtail will often harass much larger birds such as the laughing kookaburra and wedge-tailed eagle. It has responded well to human alteration of the landscape and is a common sight in urban lawns, parks, and gardens. It is widely featured in Aboriginal folklore around Australia and New Guinea in a variety of roles, from stealer of secrets and liar to a good omen for successful crops.Photograph credit: JJ Harrison
