Description

Classification: Genus Larus (Larus); Subfamily Larinae (Larinae); Family Gulls (Laridae)
General:The yellow-legged gull is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.^[2] [more]
Vocalization:Voice more nasal than Herring Gull, but ID by sound difficult. [Link]
