Resumen

We describe the results of a survey of breedingseabirds carried out between 2000 and 2002 in the northern islets of Lanzarote, CanaryIslands, with particular emphasis on their status and distribution. For White-faced Storm-petrel Pelagodroma marina, Madeiran Storm-petrel Oceanodroma castro, Lesser Black-backed Gull Larus [fuscus] graellsii and Yellow-legged Gull Larus cachinnans atlantis, somenew colonies were discovered on different islets. All species have maintained their numbersover the last 15 years, with the exception of the Yellow-legged Gull, which has undergone awell-documented increase; in 1987, about 400 breeding pairs were estimated but during thepresent study, almost 1000 pairs were counted. In addition, some comments on threats tothese seabird populations are presented. On La Graciosa, feral cats are a major predator ofthe European Storm-petrel population, killing more than 50 birds during this study alone
