An American herring gull (Larus smithsonianus) is a large gull found throughout the Northern Hemisphere, especially in North America. They are a recognized species of European herring gulls and are also known as the Smithsonian gull.
These birds were very commonly observed throughout the North American countries until the second half of the 20th century.
However in the past 40 years, the population of these North American birds has faced a significant decline throughout their range. Decreasing food supply and changing climate conditions in their natural habitats are some of the major threats that American herring gulls are experiencing within their range.
The American herring gull can breed on various types of habitats ranging from coastal areas to tundra forests and agricultural or urban landscapes. Most commonly, the gull constructs its roosting nest along the Atlantic coast or near the Great Lakes in the breeding season.
During winter migration, gulls fly away to distant coasts. Most birds fly away from the tundra forests and modified landscapes and populate the Gulf Coast in winter. Traces of vagrant populations have also been recorded inColombia, Ecuador, Peru, and Venezuela.

What class of animal does an American herring gull belong to?
The American herring gull (Larus smithsonianus) of Charadriiformes order and Laridae family belong to the class Aves, the common class for all birds.
How many American herring gulls are there in the world?
The global population of American herring gulls (Larus smithsonianus) is estimated to range between 430,000-520,000 individuals. They are following a declining population trend at present. Many recognized bird survey teams have agreed that American herring gulls require an elaborate population monitoring program for establishing an increasing population trend of this bird.
Where does an American herring gull live?
The American herring gull (Larus smithsonianus) has an extensive range map and they are distributed throughout a large extent in the northern part of North America. The breeding range of these birds lies just below the Arctic Circle in the United States and Canada.
They breed across central and south Alaska extending to the Great Lakes of the United States. Further south, the birds nest along the northeast coast of the United States where they occur throughout the stretch of southern Maine to North Carolina.
American herring gulls inhabit most parts of Canada except the lower border of the country in the south and the Arctic regions located far north. Few birds that live in the south of Alaska, the Great Lakes, and the northeast coast of the USA are residential in their range and they generally do not migrate.
However, most birds travel south along the Atlantic coast and Pacific coast in the freezing winter. Winter migration may even range as south as Mexico and Central America while some gulls move to Hawaii.
What is an American herring gull's habitat?
The American herring gull (Larus smithsonianus) prefers to inhabit a coastal habitat. They are found in small groups near water bodies preferably in inland habitats.
The gull species also nest on wet fields, rooftops, garbage dumps, lakes, and reservoirs. These birds are often observed to forage and feed at sea, lakes, rivers, and on beaches, mudflats, and fields. Inhabiting places near water fulfils their requirement of constant food supply like fish and invertebrates and also provides them shelter from their predators.
Who do American herring gulls live with?
The American herring gull (Larus smithsonianus) is a gregarious bird species that nest in spaced out colonies. Although the birds are not solitary in nature, most of their interaction with neighbor colonies seems to be forced.
They prefer to nest in very loose colonies rather than staying in tightly packed colonies. American herring gulls are very protective of their colonies and the dominant adults protect the chicks in the colonies.
How long does an American herring gull live?
The species of herring gulls (Larus smithsonianus) can live up to 30 years of age. However, most of the birds tend to die much before that in the wild due to both natural and man made causes.
How do they reproduce?
American herring gulls (Larus smithsonianus) are generally monogamous in nature with rare instances of polygamy including one male and two females in a single incubating territory. The bird pairs are formed prior to the breeding season between March and April.
They fly to their breeding nest with their respective pairs and stay there for two months. The breeding site is selected by both males and females.
The nest is formed by gathering several scrapes on the ground and is lined by vegetation on both sides.
American herring gull males do not perform any particular mating displays before breeding. The female bird approaches a male by making begging calls.
If the male responds to the begging call of the female herring gull, she flies encircling the male and produces begging calls at a higher intensity. If the female eats the food offered by the male bird during this process, it directly leads to breeding.
A female American herring gull generally lays three eggs in a breeding season at regular intervals of one to two days. The males guard the females very intensely five days before laying the eggs and during the incubation period.
The eggs hatch after an incubation period of 30-32 days from breeding. Both parents take care of the eggs and the chicks.
The young ones fly after six to seven weeks under the supervision of the parents. The parents take care of the young birds and feed them until they turn six months old.
What is their conservation status?
According to the IUCN Red List, American herring gulls (Larus smithsonianus) fall under the category of a Least Concern species. The large range map is one of the major factors that contribute to their status in the Red List. Apart from that, these birds seem to have a fairly large population currently in spite of their decreasing population trend.
The large population of the American herring gull and their extremely vast range do not let them fall under the threshold of endangered species. However, these birds face some significant threats that are likely to affect their population trend.
