Picocoraciae is aclade that contains the orderBucerotiformes (hornbills and hoopoes) and the cladePicodynastornithes (containing birds like kingfishers and rollers, and woodpeckers and toucans) supported by various genetic analysis[1][2][3][4][5][6] and morphological studies.[7] While these studies supported a sister grouping of Coraciiformes and Piciformes, a large scale, sparse supermatrix has suggested alternative sister relationship between Bucerotiformes and Piciformes instead.[8] This group was defined in thePhyloCode by George Sangster and colleagues in 2022 as "the least inclusive crown clade containingBuceros rhinoceros,Coracias garrulus, andPicus viridis".[9]
