Abstract
SUMMARYThe head‐scratching behaviour pattern is a valid taxonomic character. It supports the divisions within the Psittaciformes in the case of the Strigopinae, Nestorinae, Loriinae, and Kakatoeinae, but indicates that the Psittacinae are comprised of a number of groups. Some evolutionary problems arising out of the study of the scratching pattern are outlined.
