Bucerotiformes is an order of birds that contains the , , and .[Yuri, T. et al. (2013) Parsimony and Model-Based Analyses of Indels in Avian Nuclear Genes Reveal Congruent and Incongruent Phylogenetic Signals. Biology, 2(1):419-444. doi:10.3390/biology2010419][Jarvis, E.D. et al. (2014) Whole-genome analyses resolve early branches in the tree of life of modern birds. Science, 346(6215):1320-1331.] The clade is distributed in Africa, Asia, Europe and Melanesia.
Systematics
Recent genetic data show that
Bucorvidae and
Bycanistes form a clade outside the rest of the hornbill lineage.
[Woodruff, D. S. & Srikwan, S. 2011. Molecular genetics and the conservation of hornbills in fragmented landscapes. In Poonswad, P. (ed) The Asian Hornbills: Ecology and Conservation. National Center for Genetic Engineering and Biotechnology, Bangkok, pp. 257–264.] They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia. The hoopoe subspecies Saint Helena hoopoe and the Madagascar subspecies are sometimes elevated to a full species. The two wood hoopoe genera,
Phoeniculus and
Rhinopomastus, appear to have diverged about 10 million years ago, so some systematists treat them as separate
subfamily or even separate families.

Extinct Messelirrisoridae and Laurillardiidae families were both considered to be stem groups of a previously categorized Upupiformes order prior to it being subcategorized into Bucerotiformes.[Mayr, Gerald (2009). "Paleogene Fossil Birds". In Springer Science & Business Media, 21 April 2009, p. 194. ]
