Are There Different Kinds of Seagulls?

Gulls are a diverse group of birds with over 50 to 60 different species found worldwide. They belong to the family Laridae, which also includes terns, skimmers, and auks.

Gulls are medium-to-large sized birds with long wings, webbed feet, and hooked beaks. They are found in a variety of habitats, including coastal areas, lakes, rivers, and even urban environments.

Some gull species are highly specialized, while others are more generalists. For example, the Sabine's Gull has unique breeding and feeding behaviors, such as nesting in the Arctic tundra and foraging primarily on open water for small marine invertebrates. Other gull species like the Herring Gull are more generalists and have a broader diet and habitat range, making them adaptable to a wider range of environments and food sources.

Gulls play an important role in marine ecosystems. They help to control populations of fish, shellfish, and other marine organisms. Gulls are also scavengers, and they often feed on garbage and other human-generated waste.

Let's take a closer look at some of the most distinctive species of seagulls and their main characteristics.

Heermann's Gull, scientifically known as Larus heermanni, is named after the American ornithologist Adolphus Heermann, who first described it.

These gulls are primarily found along the western coast of North America, where they breed and nest. During the breeding season, they inhabit coastal areas of California and the Gulf of California in Mexico. However, Heermann's Gulls are known to be migratory birds, and they undertake extensive migrations, often as far south as Central America, during the non-breeding season.

In their adult breeding plumage, they have gray feathers on their upperparts, complemented by a white head and underparts. Their legs are dark red, and they have a distinctive black-tipped bill. In contrast, during the non-breeding season, their plumage becomes more mottled, with a less-defined white head.

These gulls are highly adaptable and opportunistic feeders, with a diet that includes a variety of marine prey, such as fish, squid, and invertebrates. They are also known to scavenge for food, often frequenting coastal towns and fishing ports.

The Swallow-tailed Gull, scientifically known as Creagrus furcatus, is the only fully nocturnal gull globally. These gulls feed primarily at night, using their excellent night vision to hunt squid and small fish.

They are only found on the Galápagos Islands, a group of islands in the Pacific Ocean off the coast of South America. These islands are known for their unique plants and animals.

Swallow-tailed Gulls have white plumage, black wings and tail, and a distinctive red eye ring, giving them a unique appearance.

Swallow-tailed Gulls build their nests on rocky cliffs along the Galápagos Islands' shores. Both male and female birds help to incubate the eggs and raise the chicks.

The Larus pacificus, commonly known as the Pacific Gull, is a species of seagull that inhabits the coastal regions of southern Australia. They prefer habitats such as sandy beaches, rocky shores, and estuaries, making them a common sight along Australia's extensive coastline.

Pacific Gulls are large birds with a wingspan that can reach up to 1.6 meters (5.2 feet). Their plumage is striking, with a white head, neck, and underparts contrasting sharply with their dark slate-gray wings and back. They have a distinctive yellow orbital ring around their eyes, which adds to their charismatic appearance.

These seagulls are opportunistic feeders and are known for their diverse diet. They forage for a wide range of prey, including fish, crustaceans, mollusks, small mammals, and even scavenging for scraps from human settlements.

Larus argentatus, commonly known as the Herring Gull, is a versatile and adaptable seagull species. Herring Gulls are found across a vast range, including North America, Europe, and Asia. They inhabit coastal areas, estuaries, lakes, and even urban environments, making them one of the most widely distributed gull species.

These gulls are large with a wingspan that can exceed 1.5 meters (5 feet). They have a white head and body with gray wings marked by a prominent black wingtip. Their legs are pink, and they have a distinctive yellow bill with a red spot towards the tip.

These gulls are known for their intelligence and resourcefulness. They are excellent scavengers and are often seen near human settlements searching for food scraps. Herring Gulls are also highly vocal, with a variety of calls used for communication and establishing territory.

The Bonaparte's Gull, scientifically known as Chroicocephalus philadelphia, is a charming and petite seagull species. These gulls prefer the northern parts of North America, with their breeding grounds stretching from Alaska to eastern Canada. However, they're not homebodies, as they migrate south during winter, often reaching the Gulf of Mexico and the Caribbean.

Bonaparte's Gulls are among the smaller gull species. Their plumage is a mix of white and gray, featuring a distinctive black head during the breeding season.

Their diet mainly consists of aquatic insects, small fish, crustaceans, and the occasional tidbit from the surface. Bonaparte's Gulls are known for their graceful aerial foraging skills. They have a distinctive hunting technique, hovering above the water's surface before diving gracefully to catch prey. Their calls are gentle, quite distinct from the cacophony of larger gull species.

Ross's Gull, scientifically named Rhodostethia rosea, is a rare species of seagull. These gulls are native to the Arctic regions, particularly the northern parts of North America and Eurasia. While they breed in the Arctic, they migrate south during winter, venturing into areas like the northern United States and parts of Europe and Asia.

The Ross's Gull is a small and delicate seagull. Its distinctive features include a pale pink plumage, which intensifies during the breeding season. Its petite size and graceful appearance set it apart from its larger, more boisterous relatives.

These gulls primarily feed on small aquatic invertebrates, including crustaceans and insects. They are known for their buoyant and agile flight as they forage for food along coastlines and water bodies.

Ross's Gulls are known for their unique and charming courtship displays. They often engage in synchronized flights and vocalizations during mating rituals. They have a soft, melodious call, a contrast to the raucous cries of larger gulls.

The Black-legged Kittiwake, scientifically named Rissa tridactyla, is a species of seagull predominantly found in the Northern Hemisphere, with significant populations in the North Atlantic and North Pacific.

Black-legged Kittiwakes are medium-sized gulls with striking black legs, hence their name. They have a pristine white body with elegant gray wings and a subtle yellow bill. Their slender build and agile flight make them well-suited for their coastal habitats.

These gulls have a varied diet that includes small fish, marine invertebrates, and zooplankton. They are well adapted to foraging at sea and are often seen plunging into the water to catch their prey.

Black-legged Kittiwakes are known for their melodious calls, resembling their name "kitti-wake." They are highly social birds, often seen in large colonies during the breeding season. They are known for their cliff-nesting colonies on coastal cliffs and islands. They build nests in unracheable plaves to protect their eggs and chicks from predators.

Sabine's Gull, scientifically named Xema sabini, is a species of gull primarily found in the high Arctic during their breeding season. They nest on rocky cliffs and tundra habitats in the Arctic regions of North America, Europe, and Asia. However, they migrate long distances to spend the winter in pelagic marine environments.

These gulls have a black hood, a white face with a black eye patch, and a delicate, forked tail. During the breeding season, their plumage is adorned with shades of gray and elegant patterns.

Sabine's Gulls have a diverse diet, primarily consisting of small fish, insects, and marine invertebrates. They are skilled flyers and often perform aerial maneuvers to catch their prey.

They are social birds and often form flocks, especially during migration. Their nesting sites in remote Arctic regions provide some protection from predators.
