==Description==
Ibises are known to have a rounded body with long legs and a long S-shaped neck. There are 30 different species worldwide and they all show variations on the same body form.〔Boev, Z. 1998. Presence of Bald Ibises (Geronticus Wagler, 1832) (Threskiornithidae - Aves) in the Late Pliocene of Bulgaria. - Geologica Balcanica, 28 (1-2): 45-52.2〕 Some are crested and some are bald behind their heads.〔
The spot-breasted ibis, like other ibises, has long legs and a long bill.〔 They also have a crest at the back of their head. Unlike other ibises they have a short neck. Their wing length is 270-290 mm, their bill length is 115-130 mm and their tarsus length is 56-65 mm. Their plumage varies but appears to be most commonly brownish – blue.〔 A small, dark ibis, the best distinguishing feature is suggested by its name; the buff-spotted neck and breast is diagnostic. Otherwise, the upperparts are uniformly dark, with blue skin surrounding the eyes (smaller in females).〔Sinclair, I, and Ryan, P. 2003. Birds of Africa: south of the Sahara. Struck Nature, Cape Town, South Africa〕 Flying birds can be distinguished by their broad wings and short tail.〔 The juvenile is duller, and has a shorter crest.〔
