Gull

Gulls are birds that live near water.

They are often grey and white. They have feet with skin between their toes. This helps them swim.

Gulls are very smart. They can find food in many places. They eat fish and small bugs. Some gulls even use bread to catch fish!

These birds live in big groups. They build nests out of plants. They lay two or three eggs. The babies are born with dark fuzz. They can move right away.

Gulls can live for a long time. Some can live for many years. They are found all over the world.

Gulls are clever seabirds found all over the world.

They live on every continent. Some even live near the icy Arctic. Most gulls are grey and white. They have heavy bodies and long wings. Their feet are webbed to help them swim.

Gulls are very smart eaters. They can eat almost anything. This includes fish, insects, and even seeds. Some gulls are very resourceful. One type uses bread as bait to catch goldfish!

They can also find food by following ships. They may even drop shells on hard rocks to break them open. This takes practice, so older birds are often better at it.

Gulls like to live in big, noisy groups called colonies. They build nests using plants. Most gulls lay two or three speckled eggs.

When the babies hatch, they have dark fuzz. They can move around right away. Some large gulls can live for a very long time. One bird lived to be 49 years old!

Gulls are amazing seabirds found almost everywhere on Earth.

They live on every continent, even near the icy edges of Antarctica. Some species live in the high Arctic, while others stay in warm places like the Galapagos Islands.

Most gulls have grey or white bodies with darker wings. They have heavy bodies and long wings for flying. Their feet are fully webbed to help them swim through the water. Most gulls are very smart and live in large, noisy groups called colonies.

Gulls are very good at finding food in many different ways. They are generalists, which means they can eat many different things. They eat fish, insects, crabs, and even seeds or fruit.

Some gulls use a clever trick to eat hard shells. They fly high and drop clams onto hard rocks to break them open. This takes practice, so older birds are usually better at it than young birds. Some gulls even use pieces of bread as bait to catch goldfish!

They can find food by swimming, walking on land, or even snatching it from the air.

Scientists have studied how gulls live and eat for a long time. Many gulls are related to birds called terns and skimmers. In the past, people used the name "mew" for these birds. This name actually comes from the sounds they make. Their calls can be harsh, wailing, or squawking.

Some larger gulls can live for a very long time. A European herring gull was once recorded living to be 49 years old. This shows how long these birds can thrive in the wild.

Gulls come in many different sizes and shapes. The little gull is only about 25 centimeters long. The great black-backed gull is much larger at 75 centimeters.

Most gulls have rounded tails, but a few have different shapes. The Sabine's gull has a forked tail, and the Ross's gull has a wedge-shaped tail. Their bills can be different colors too. Larger white-headed gulls often have yellow bills with a red spot. Smaller gulls might have bills that are red, dark red, or black.

It is interesting to see how gulls live near people. Many gulls have learned to live in human towns and cities. They often follow fishing boats to find scraps of food.

Some gulls even rely on human landfills to find things to eat. Because they are so resourceful, they can survive even when their natural food changes. This ability to adapt helps them stay successful in a changing world. They are truly some of the most capable birds in the sea.

Gulls are highly adaptable seabirds belonging to the subfamily Larinae. They are closely related to terns and skimmers within the family Laridae.

While they are most famously associated with the ocean, they are actually generalist species. This means they can survive in many different environments, including freshwater and land. They are found on every continent, including the margins of Antarctica and the high Arctic.

Because they can live almost anywhere, they are considered to have a cosmopolitan distribution. This wide reach makes them one of the most successful bird groups on Earth.

Physically, gulls are built for versatility in swimming, flying, and walking. They generally possess heavy bodies, long wings, and moderately long necks. Most species have rounded tails, though exceptions like the Sabine's gull have forked tails. Their feet are fully webbed, which assists in swimming. Their bills are often heavy and slightly hooked to help with feeding. In larger white-headed species, the bill is often yellow with a red spot.

Smaller species may have bills that are red, dark red, or black. This physical diversity allows them to fill many different roles in nature.

Feeding is a complex process that relies on opportunistic behavior. Gulls are piscivores, meaning they eat fish, but they are also carnivores that eat many other things. Their diet includes crustaceans, molluscs, insects, rodents, and even eggs.

They use many different methods to capture this food. Some gulls can hawk insects while flying, while others plunge-dive into the water.

Some species even use a learned technique of dropping heavy shells onto hard surfaces to break them open. This specific skill is often better in older birds than in younger ones.

To manage the salt from their diet, gulls have a specialized biological mechanism. They possess exocrine glands located in the supraorbital grooves of their skull. These glands allow them to excrete salt through their nostrils.

This process helps the kidneys maintain a proper electrolyte balance. This biological adaptation is what allows them to drink salt water and thrive in marine environments. Without these glands, the salt intake from fish and seawater would be difficult to manage.

Socially, gulls are known for being intelligent and highly organized. They often nest in large, noisy colonies that are densely packed together.

Many species are monogamous and show mate fidelity, meaning they stay with the same partner for life. They also demonstrate complex social structures, such as mobbing behavior. In mobbing, a group of gulls will attack and harass an intruder or a predator. This collective action helps protect the colony and its many nests.

Their young are precocial, meaning they are born with dark, mottled down and are mobile immediately after hatching.

Historically, the naming of gulls has been tied to their vocalizations. An older name for these birds is "mew," which is an onomatopoeic term. This means the name is derived from the actual sounds the birds make.

Their calls are often described as harsh, wailing, or squawking. While the genus *Larus* was once used for most gulls, modern science has revised this. Scientists now recognize that the old arrangement was polyphyletic, meaning the birds did not all share a single immediate common ancestor. This led to the creation of several different genera to better reflect their true relationships.

Human activity has a massive impact on gull populations and their behavior. Many gulls have learned to coexist with humans by scavenging in urban habitats.

They often follow fishing boats or visit landfills to find predictable food sources. Some species, like the lesser black-backed gull, are heavily influenced by human fishing ports. While this provides food, it can also cause shifts in their natural diet. For example, when fish stocks like sardines decline due to overfishing, gulls may shift to eating more crustaceans. This ability to change their diet shows the incredible resilience of the species.
