Coraciiformes

This bird order houses many colorful birds, such as kingfishers, bee-eaters, rollers, motmots and todies. There is very little literature on hybridization in the Coraciiformes.

Introgression between two subspecies of the Dwarf Kingfisher (Ceyx erithaca) has been documented (Lim, Sheldon & Moyle, 2010; Sims, 1959).

An intergeneric hybrid between Amazonian Motmot (Momotus momota) and Rufous-capped Motmot (Baryphthengus ruficapillus) in Brazil has been morphologically described (Marcondes et al., 2013). Another intergeneric hybrid between Amazonian Motmot and Rufous Motmot (Baryphthengus martii) was reported in the Amazonia National Park (Cerqueira et al., 2020).
