The Green wood hoopoe (Phoeniculus purpureus), is a specie of large, up to 44 cm (17 in) long, wood hoopoe native to Africa. It is a member of the family Phoeniculidae, and was formerly known as the red-billed wood hoopoe. This abundant species is a metallic dark green, with a purple back and very long diamond-shaped purple tail. Distinctive white markings on the wings and white chevrons on the tail edges make it easily identifiable, as does its long, thin, curved red bill. Sexes are similar, but immatures have a black bill.
