Key words: Cory's Shearwater, Scopoli's Shearwater, Calonectris shearwater identification


Abstract

The genus Calonectris contains four species: Streaked Shearwater C. leucomelas (which breeds in the North Pacific mainly on islands off Korea, Japan, and Taiwan), Scopoli's Shearwater C. diomedea (which breeds mainly in the Mediterranean Sea), Cory's Shearwater C. borealis (which breeds mainly on islands in the Northeast Atlantic Ocean), and Cape Verde Shearwater C. edwardsii (which is an endemic breeder of the Cape Verde Islands). In this study, we were concerned with the field separation of the cryptic pair Scopoli's Shearwater and Cory's Shearwater, only briefly considering the more easily recognised Streaked Shearwater and Cape Verde Shearwater. Background information is summarised in Appendix 1, available on the website).
