The Black-necked Stork, with its beautiful iridescent head, neck and back plumage, is native to southern Asia and Australasia.
The Saddle-billed Stork is native to sub-Saharan Africa. Related to the Black-necked Stork of Asia (above), it has black legs with prominent pink knees
and a yellow and red "saddle" on its bill.
Male and female have similar plumage and "saddles" but the female, right, has yellow irises rather than brown.
