Cavitaves

Cavitaves is a clade that contains the order Leptosomiformes (cuckoo roller) and the clade Eucavitaves (a large assemblage of birds that includes woodpeckers, kingfishers and trogons).^{[1][2][3][4][5][6]} This group was defined in the PhyloCode by George Sangster and colleagues in 2022 as "the least inclusive crown clade containing Leptosomus discolor and Picus viridis".^[7] The name refers to the fact that the majority of them nest in cavities.
