Last Updated on April 4, 2023 by Susan Levitt

Western Gulls are majestic creatures, soaring across the sky with grace and beauty. These seabirds are beloved by many, especially those who live along the western coast of North America. But do you know just how fascinating these birds are? Let’s take a closer look at the Western Gull and discover why they’re such a delight to observe.

The Western Gull is a large seabird that’s found in coastal regions from Alaska to Baja California. It’s closely related to other gull species like the Glaucous-winged Gull and the California Gull. Its body measures 18-24 inches long with a wingspan of about 4 feet, making it one of the larger gull species in its area. The male and female have similar markings: a white head, neck, and tail with grey wings and back. Juveniles have mottled brown feathers until they reach maturity at three years old.

The Western Gull is an opportunistic feeder that forages for food both in the air and on land. It feeds mainly on fish, but will also eat crustaceans, insects, rodents, eggs, carrion, and human refuse. It often scavenges alongside other seabirds like cormorants or terns in order to find food more easily. With its impressive size and varied diet, it’s no wonder that these birds are so iconic!


The western gull, or Larus occidentalis, is a large seabird species found along the coasts of western North America. It belongs to the Laridae family and is closely related to the California gull. This species has a whitish gray body with brownish-gray wings and a yellow bill. Its eyes are typically dark and its legs are pinkish-orange in color.

Western gulls inhabit coastal regions from Alaska to Baja California, as well as some inland areas such as the Great Salt Lake in Utah. They prefer habitats close to water for foraging and nesting, including rocky shores, sandy beaches, tidal flats, estuaries and other wetlands. They can also be found in some agricultural areas.

Distribution & Habitat

The western gull is a bird species that ranges from Alaska to Mexico, residing along the Pacific Coast. Interestingly, approximately 99% of these birds are found in the United States and Canada. Their primary habitats include:

  • Coastal areas
  • Rocky shores
  • Offshore islands
  • Lagoons
    In general, these gulls prefer open habitats near the shoreline with abundant nesting locations. They often make their nests on cliffs or ledges near rivers, lakes, and marshes. Western gulls also migrate seasonally in search of food sources such as fish, crustaceans, insects, and mollusks. Moving into the physical characteristics of western gulls…

Physical Characteristics

The Western Gull is a large seabird with a wingspan of up to 52 inches. Its plumage is mainly white and gray, with black outer primary feathers and pink legs. Its bill is bright yellow with a red spot near the tip. The male and female are almost identical in appearance, although the female’s bill is slightly smaller.

Western Gulls have strong feet which enable them to walk on land and swim in the sea. They can be seen wading on shorelines and flying high above the ocean. They are agile flyers, able to take off quickly from water or land surfaces and soar effortlessly for long distances. Their flight pattern consists of alternating glides and flaps as they search for food or migrate across oceans. With such powerful wings, they can reach speeds of up to 55 mph!

The Western Gull’s diet and feeding habits will be discussed next.

Diet & Feeding Habits

The western gull is a voracious consumer of its environment, using its keen eyesight to locate and capture prey. Its diet consists largely of fish, mollusks, squid, crustaceans, and insects.PiscivoreMolluscivoreInsectivore

It has also been known to scavenge on carrion and even steal food from other birds. By taking advantage of the different resources available in its habitat, the western gull is able to sustain itself throughout the year. The gull will often fly long distances to reach feeding grounds or follow ships in search of food. In addition, these birds are known to employ sophisticated techniques while fishing such as ‘tossing’ mussels onto rocks or ‘plunging’ into shallow water after prey. This versatility allows them to make use of a wide variety of food sources that would otherwise be unavailable. Thus, the diet and feeding habits of the western gull prove it is an adaptable species with a diverse palate. With this knowledge in hand we can turn our attention towards their breeding & nesting behaviour.

Breeding & Nesting Behaviour

Western gulls are well-known for their elaborate nesting and breeding behaviours. They prefer to nest near the coast, usually on islands off the coasts of California and Oregon. Their nesting season begins in late April or early May and can last until August or September. Adults build nests made of grass, seaweed, mud, and other debris. The female lays two to three eggs which are incubated by both parents for 22-27 days before hatching.

Once hatched, young gulls stay with their parents for up to a month while they learn how to fly and feed themselves. After they leave the nest, they may remain in the area with other juveniles or migrate southward along the coast. As they prepare to migrate, western gulls gather in large groups before taking flight together. This communal behavior is essential for teaching young birds how to properly navigate migratory routes.

Migration Patterns

Western Gulls are migratory birds, meaning they travel between their breeding grounds and wintering habitats. Breeding grounds for Western Gulls are located in California, Oregon, and Washington. In springtime, they’ll head north to Alaska and British Columbia to breed during the summer months. They may also migrate as far south as Mexico’s Baja Peninsula. During the winter months, Western Gulls will often head down to coastal areas of northern Mexico and central California.

Western Gulls follow a regular migration pattern that can be observed year after year- but some individuals may deviate from this path if environmental conditions change or food sources become scarce. They may also use different routes or take longer flying times depending on the season and weather conditions.

Predators & Threats

As the old adage goes, “the early bird gets the worm.” In this case, the same is true for Western Gulls during their migration patterns. While on their journey, they face a variety of predators and threats that could put an end to their journey.

The primary predators of the Western Gull are hawks, eagles, and falcons. They will try to attack them mid-flight or when they land in search of food. Other predators include owls and large fish like sharks who can snatch up Western Gulls from the sea surface. To avoid these predators, gulls have been known to fly in flocks or practice evasive techniques such as changing direction quickly or diving aggressively.

In addition to predation threats from other animals, Western Gulls also face other risks such as human related disturbances at nesting sites or being caught in fishing nets and lines. To help protect them from these dangers, conservationists have created buffer zones around nesting sites and advocated for more responsible fishing practices that don’t harm seabirds. With these new protective measures, Western Gull populations can remain healthy and continue their migrations safely each year. As we move forward into the next section on conservation status, it is important that we keep these threats in mind while looking ahead towards our next steps.

Conservation Status

The western gull is classified as a species of Least Concern by the International Union for Conservation of Nature (IUCN). This means that it is not considered to be endangered or vulnerable due to its widespread range and stable population size.

This seabird can be found in many areas along the Pacific coast, including:

  • The Aleutian Islands and Alaska
  • British Columbia
  • Southern California
  • Baja California

Despite this, the western gull has been impacted by human activities such as hunting, pollution, and habitat destruction. This has caused some populations to decline. To help protect these birds, several conservation efforts are being undertaken, including:

  • Establishing protected areas where they can nest and feed in peace
  • Reducing light pollution that could disrupt their breeding cycle
  • Monitoring fishing nets to ensure they don’t become entangled in them
    These measures aim to ensure that the western gull continues to thrive in its natural habitat. With the right precautions, this species can remain resilient against any threats.

With its wide distribution range, there are plenty of opportunities for people to view these birds in their natural environment.

Viewing Opportunities

Having discussed the conservation status of the Western Gull, this section will focus on viewing opportunities. The Western Gull is often very visible along the coastlines of California. They can be seen basking in the sun and preening their feathers while perched atop rocks and pilings along the shoreline.

Western Gulls are also present in marine habitats such as mudflats, estuaries, and kelp beds. These birds may be more difficult to spot in these areas but can usually be heard from a distance due to their loud cackles. Birders should take caution when attempting to observe Western Gulls, as they are known for being aggressive towards other gull species that approach their nesting sites.

With a bit of patience and some luck, birders can have an opportunity to observe these majestic seabirds in their natural habitat. Now onto interesting facts about the Western Gull!

The longest recorded age for a western gull was 23 years old, which is significantly longer than what is expected from them in their natural habitat. It’s clear that while age can vary significantly depending on the environment they inhabit, western gulls generally have an average lifespan of around 15 years in the wild and up to 25 years in captivity.

How Large Is The Population Of Western Gulls?

When it comes to population size, it’s difficult to get an accurate count of many species. This is especially true of the western gull, a seabird that inhabits the west coast of North America.

It’s estimated that there are approximately 200,000 pairs of western gulls living along the Pacific coast. This population is believed to be stable, although there have been reports of declines in certain areas. The reasons for this are unclear but could be due to human disturbance or changes in their food supply.

In addition to their main breeding sites on the west coast, western gulls can also be found in Alaska and other parts of Canada during migration season. They also sometimes travel further south than usual during winter months, as far as California and Mexico. Overall, the population appears healthy and is not currently facing any major threats from human activities.

What Is The Most Common Nesting Material Used By Western Gulls?

Symbolism is often used to convey a deeper meaning for the audience. In the same way, nesting material for birds can be seen as a symbol of security and safety. For western gulls, this is no different; they instinctively choose nest materials that will best protect their young and provide them with a safe environment.

When it comes to nesting material, western gulls tend to favor vegetation over other materials like mud or sand. This includes grasses, reeds, leaves and twigs. The thick layers of these materials provide insulation and help keep the eggs warm during incubation. They also help obscure the nest from potential predators by providing camouflage-like protection. Additionally, vegetation helps hold moisture which is essential in maintaining healthy eggs and chicks until they are ready to fledge. All these reasons make vegetation the most common nesting material used by western gulls.

Nest building is an important part of any bird’s life cycle, but especially so for western gulls who depend on these materials to ensure their chicks’ safety and success in life.

What Is The Relationship Between Western Gulls And Other Seabirds?

The relationship between seabirds is an interesting one, as some species of birds rely on each other for nesting materials, food, and protection from predators. Western Gulls are no exception to this; they share many interrelationships with other types of seabirds. Here are a few examples:

  1. Many seabirds form mixed colonies with Western Gulls in order to gain the advantages of protection from predators that larger colonies can offer.

  2. Seabirds such as terns and alcids use the rocky cliffs where Western Gulls nest for their own nesting sites.

  3. Herring and Ring-billed Gulls often share fisheries with Western Gulls, which helps them to find food more easily.

  4. Auklets and murres sometimes use the feathers of Western Gulls to line their nests, making them more comfortable for incubating eggs or chicks.

These relationships demonstrate how essential it is for different species of seabirds to cooperate in order to survive and thrive in the marine environment together. By working together and sharing resources, these birds can create better habitats for themselves and make it easier to feed their young successfully.
