It has a long, curved bill. Its plumage is bright scarlet with the distal third of the black wings. Its legs are pink just like its bill which turns black during the reproductive season. The immature ones have the head and neck striated or mottled with coffee and white and the upper parts of dark grayish brown. Its lower parts and rump are white and sometimes pink mottled.

The brilliant red color of the scarlet ibis comes from carotene found in the crustaceans on which it feeds.

These birds are rather quiet, only grunting or croaking on breeding grounds.
