Megaceryle maximus (Linneaus 1758), the extantgiant kingfisher.

Megaceryle alcyon (Linneaus 1758), the extant belted kingfisher, had an enlarged beak on an enlarged skull with a shorter neck. As in parrots, by convergence, the nares have migrated back to the orbit.

Jabiru mycteria (Lichtenstein 1819, South America) was a stork-like kingfisher possibly congeneric with the African maribou. Note the high small naris on the ventrally convex rostrum, as in the belted kingfisher.

Leptoptilos crumenifer (Lesson 1831) from equatorial Africa is the extant marabou stork. It is almost identical to Jabiru, another long-legged kingfisher, also not a stork.
