About the American Herring Gull
The American herring gull (Larus smithsonianus or Larus argentatus smithsonianus), also known as the Arctic herring gull or Smithsonian gull, is a large gull that breeds in North America, where it is treated by the American Ornithological Society as distinct from the European herring gull (Larus argentatus).
Adults are white with gray back and wings, black wingtips with white spots, and pink legs. Immature birds are gray-brown and are darker and more uniform than European herring gulls, with a darker tail. As is common with other gulls, they are colloquially referred to simply as seagulls.
It occurs in a variety of habitats including coasts, lakes, rivers, parking lots and garbage dumps. Its broad diet includes invertebrates, fish, and many other items. It usually nests near water, laying around three eggs in a scrape on the ground.
This gull was first described as a new species in 1862 by Elliott Coues based on a series of specimens from the Smithsonian Institution. It was later reclassified as a subspecies of the herring gull (Larus argentatus). The genus name is from Latin Larus, which refers to a gull or other large seabird. The species name smithsonianus commemorates... Wikipedia →
