The bird was named for its similarity in colouration to the Eurasian magpie; it was a common practice for early settlers to name plants and animals after European counterparts.[11] However, the Eurasian magpie is a member of the Corvidae, while its Australian counterpart is placed in the family Artamidae (although both are members of a broad corvid lineage).
