They contain a vast diversity of omnivorous and carnivorous songbirds widespread in Africa and Australia, many of which superficially resemble shrikes.
It was defined and named by Cacraft and colleagues in 2004 and contains the bushshrikes (Malaconotidae), helmetshrikes (Prionopidae), ioras (Aegithinidae), vangas (Vangidae) and the Australian butcherbirds, magpies, currawongs and woodswallows (Artamidae).
[1] Molecular analysis in 2006 added the Bornean bristlehead to the group, though its position in the Malconotoidea is unclear.
[2] In 2012, Jerome Fuchs and colleagues extensively analysed the Malaconotoidea (called by them Malaconotidea), using both mitochondrial and nuclear DNA.
[3] A cladistic study of the bony characteristics of the skulls of various Malaconotoidea and relatives, and focussing on vangas, published in 2008, found broad agreement in the inclusion of woodswallows, butcherbirds and vangas in Malaconotoidea, but also yielded some results at odds with other studies—the red-backed shrike, crested drongo and magpie-lark were nested within the group.
