Cyanoramphus malherbi (Souance 1857) is relegated to synonymy with C. auriceps (Kuhl 1820) after cross-breeding in captivity showed that both are colour morphs of one species. The resulting parent-offspring data can be most simply explained by the Mendelian theory of dominant/recessive inheritance at a single locus, the factor for yellow-crowned being dominant.
