Larus argentatus |
The Herring gull, Larus argentatus is a large gull which breeds across North America Europe and Asia. It migrates further south in winter. Some are permanent residents on the lower Great Lakes and the east coast of North America.
The taxonomy of the Herring Gull/Lesser Black-backed Gull complex is very complicated, different authorities recognising between two and eight species.
This group has a ring distribution around the northern hemisphere. Differences between adjacent forms in this ring are fairly small, but by the time the circuit is completed, the end members, Herring Gull and Lesser Black-backed Gull, are clearly different species.
The Association of European Taxonomic Committees recognises six species:
The North American American Herring Gull is similar to argentatus, except that immature birds are much paler.
These are omnivores like most Larus gulls, and they will scavenge on rubbish tips and elsewhere, as well as seeking suitable small prey in fields or on the coast, or robbing plovers or lapwings of their catches.
Eggs, usually three, are laid on the ground or cliff ledges in colonies, and are defended vigorously by this large gull. The loud laughing call is well-known in the northern hemisphere.
