Range Description

Calonectris edwardsii is now considered a full species, having been split from Cory's Shearwater C. diomedea (Bretagnolle and Lequette 1990, Hazevoet 1995, Porter et al. 1997). It is considered locally common in Cape Verde (Hazevoet 1995), with large numbers frequently seen off the island of Raso (P. Donald in litt. 2003, C. Hazevoet in litt. 2003). The largest colonies are on Brava, Branco and Raso. Breeding is sparse on Santiago and Sao Nicolau, has never been fully established on Santo Anto (where the species is recorded as 'common' and the populations on Sal and Boavista amount to a few pairs only) (C. Hazevoet in litt. 2003). The total population has been estimated to number c.10,000 pairs since 1988-1993 (Hazevoet 1995, Nunes and Hazevoet 2001); Branco and Raso together hold the majority of the population, with 5,000-7,500 pairs estimated in 1988-1993 (Hazevoet 1995).
