This order is represented by the Ciconiidae (storks). Molecular data are limited to mitochondrial CYB and COI genes (Corrêa de Sousa et al., 2023).
Species-level phylogeny of extant Ciconiiformes according to the results of Corrêa de Sousa et al. (2023), with the distribution of each family being indicated by the colour-code used throughout this website (see Distribution code).
