The tree is based on the work by Leo Joseph and collaborators published in 2012 but with the choice of families and the number of species in each family taken from the list maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC), now the International Ornithologists' Union.
