The Coraciiformes /kɒrəˈsaɪ.ɪfɔːrmiːz/ are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies.

[citation needed] The members of this order are linked by their "slamming" behaviour, thrashing their prey onto surfaces to disarm or incapacitate them.

[4] The number of species in each family is taken from the list maintained by Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC).

At least the Eocoraciidae are very basal, but the Late Eocene (some 35 mya) Geranopteridae form a superfamily Coracioidea with the extant rollers and ground-rollers already (Mayr & Mourer-Chauviré 2000).

A recent study suggest that the following families may belong to a separate order called Bucerotiformes.
