We report for the first breeding attempt of the Lesser Black-backed Gull (Larus fuscus) in the Macaronesic Archipelago, in Alegranza Island (north of Lanzarote, Canary Islands). A nest with three eggs was found on June 2001, and at least one fledgling was seen in August with two adults. Additional observations suggest that 5-6 pairs may breed on Alegranza Island and nearby Montaña Clara Island. This is the southernmost breeding record for the species, increasing its known breeding range by 2,000 km.
