==Taxonomy and systematics==
The family Pachycephalidae was introduced (as the subfamily Pachycephalinae) by the English ornithologist [[William Swainson]] in 1832.<ref>{{cite book | last=Bock | first=Walter J. | year=1994 | title=History and Nomenclature of Avian Family-Group Names | series=Bulletin of the American Museum of Natural History | volume= 222 | publisher=American Museum of Natural History | location=New York | pages=153, 262 | hdl=2246/830 | url=http://digitallibrary.amnh.org/handle/2246/830 }}<!--Linked page allows download of the 48MB pdf--></ref><ref>{{ cite book | last1=Swainson | first1=William | author1-link=William Swainson | last2=Richardson | first2=J. | author2-link=John Richardson (naturalist) | year=1831 | title=Fauna Boreali-Americana, or, The Zoology of the Northern Parts of British America | volume=Part 2.

The genera ''[[Goldenface|Pachycare]]'', ''[[Hylocitrea]]'', the [[crested bellbird]] and the [[crested shriketit]] were previously included in the family Pachycephalidae until moved to the families [[Acanthizidae]], [[Hylocitreidae]] and [[Oreoicidae]] and [[Falcunculidae]] respectively.<ref name=ioc/> Some authorities have also placed the genus ''[[Mohoua]]'', classified in the monotypic family Mohouidae, within the family Pachycephalidae.<ref>{{cite journal |first=Zachary |last=Aidala |display-authors=etal |title=Phylogenetic relationships of the genus ''Mohoua'', endemic hosts of New Zealand's obligate brood parasitic Long-tailed Cuckoo (''Eudynamys taitensis'') |journal=Journal of Ornithology|date=June 2013 |volume=154 |issue=4 |pages=1127–1133 |doi=10.1007/s10336-013-0978-8|bibcode=2013JOrni.154.1127A |s2cid=10012326 }}</ref>
