Introduction

Previously treated as a subspecies of C. novaezelandiae but raised to species by Boon et al. (2001). Although the genetic difference between C. cooki and C. novaezelandiae is significant, and equal to or greater than other interspecific differences in the genus, they are difficult to separate morphologically and treatment as a species not recognised by some authors, e.g. del Hoyo & Collar (2014). See Christidis & Boles (2008) for further discussion.
