The monophyly of the endemic New Zealand wattlebirds (Callaeatidae) was examined through the sequencing of nuclear RAG-1 and c-mos genes and comparison to other passerine sequences. The New Zealand wattlebirds were strongly supported to be monophyletic and were nested within Corvida. An estimate for the time of divergence of the New Zealand wattlebirds indicated that the ancestors of this family arrived via transoceanic dispersal after the separation of New Zealand from Gondwana. Long branches separated the three New Zealand wattlebird genera from one another and relationships among them were unresolved, even in analyses including a further 1.5 kb of mitochondrial DNA sequences. However, most of the analyses supported either a basally diverging huia or kokako.
通过对核RAG-1和c-mos基因进行测序，并与其他雀形目序列进行比较，研究了新西兰本土垂耳鸦科（Callaeatidae）的单系性。强烈支持新西兰垂耳鸦科为单系类群，且嵌套在鸦小目中。对新西兰垂耳鸦科分歧时间的估计表明，该科的祖先在新西兰与冈瓦纳大陆分离后通过跨洋扩散抵达。长分支将新西兰垂耳鸦科的三个属彼此分开，即使在包括另外1.5 kb线粒体DNA序列的分析中，它们之间的关系也未得到解决。然而，大多数分析支持要么是基部发散的北岛垂耳鸦，要么是冠垂耳鸦。
