摘要

Until recently the species called Fea's Petrel (Pterodroma feae) was considered to be comprised of breeding populations on both the Desertas Islands and the Cape Verde Islands of the North Atlantic. The species is being split in recognition of marked differences in breeding phenology, vocalizations, and genetics between the two breeding populations, which are separated by about 2,000 km. The new taxa are Cape Verde Petrel (Pterodroma feae) and Desertas Petrel (P. deserta). P. deserta breeds on Bugio Island in the Desertas, and lays eggs in July and August. P. feae breeds in the Cape Verde Islands and lays eggs in December and January (Howell 2012,Robb et al. 2008). The vocalizations of the two forms differ (Robb et al. 2008),increasing the likelihood that the two forms will not interbreed. Recent DNA studies have indicated that separate species status is warranted (Jesus et al. 2009).
