The Shovel-billed kookaburra (Clytoceyx rex), also known as the shovel-billed kingfisher, is a species of large, approximately 33 cm (13 in) long, dark brown tree kingfisher with a heavy, short and broad bill that is unique among the kingfishers. It has a dark head with rufous stripe behind eye, a white throat, rufous neck collar and underparts, bright blue rump, brown iris, brownish-black bill with paler mandible (entire bill often appears brownish due to earth) and pale feet. Both sexes are similar in appearance, but are easily recognized from the color of the tail. The male has a dark bluish tail while female's is rufous. The juvenile has a female-like plumage with scale-patterned feathers.
