“Seagulls are symbols of versatility and freedom in traditional Native American cultures.”

Among the most tenacious and clever foragers on the planet, the seagull is a family of birds that lives near the coast. There are more than 50 documented species found all over the world. The most common species you’re probably familiar with are the European herring gull and the American herring gull, but there’s plenty of diversity across the entire family. This article will cover some interesting facts about the appearance, behavior, and diet of the seagull.

Seagull vs. Eagle

Seagulls do share some superficial resemblance with an eagle, including a large body and hooked bill, but gulls are generally not considered to be birds of prey. They are more closely related to auks, plovers, and other shorebirds, whereas eagles are related to kites and vultures.

3 Incredible Seagull Facts!

• The seagull is considered to be among the most intelligent birds in the world. Some gulls will drop a mollusk shell onto a rock to break it open. Others have been observed baiting fish with bread. One of the most amazing facts is that they can remember new foraging strategies and pass them down to the next generation of gulls.
• Unlike most animals, the seagull can drink both freshwater and saltwater. A specialized gland right above the eyes can collect and then flush out the salt right through the nostrils.
• Seagulls have a small claw halfway up the lower leg that allows them to roost on high ledges without falling off.

Where to Find the Seagull

The majority of seagulls can be found near coastal habitats all over the world, particularly in the Northern Hemisphere. Some gulls will travel far inland in the non-breeding season, but otherwise, they stick close to the ocean habitats.

Seagull Nests

Most seagulls build their nest in a hollow depression on the ground (and sometimes cliffs) out of vegetation, feathers, rope, and even plastic. The nest is usually located next to a rock, log, or bush to protect it from predators.

Seagull Scientific Name

The scientific name of the seagull family is Laridae. This comes from the Latin term Larus for a seabird.

Size, Appearance, and Behavior

Seagulls are fairly easy to identify from their big, bulky bodies, sinewy legs, long wings, and stout bills, which end in a hook. Their bodies are normally covered in white, gray, and sometimes even black plumage, but the color of the head can vary by species. While the American and European herring gulls sport white heads, several species, including the Franklin’s gull, the little gull, and the swallow-tailed gull, have black heads instead. The head plumage often turns a mottled gray (or if it’s originally black, then it will turn white) during the winter months. Seagulls can measure anywhere between 11 to 30 inches from head to tail, depending on the species.

Seagulls live in loose, scattered colonies along the coast. The colony can consist of anywhere between just a few pairs and many thousands of birds. Breeding pairs mostly stick to their own territory and defend it against intruders, but they do gather together to hunt and forage for food. Foraging trips are a raucous affair of constant motion and noise. Each bird is essentially fending for itself. They will often steal food from other animals and each other. Seagulls communicate through several distinct calls to demonstrate aggression, identify mating partners, warn the colony of a threat, and resolve a territorial dispute. Baby chicks will also beg for food from their parents.

Migration Pattern and Timing

Most species of gulls do migrate south for the winter. Some journeys take place over just a few miles to search for better foraging opportunities, while other birds complete long migrations over thousands of miles. Perhaps the longest journey is undertaken by Franklin’s gull, which migrates all the way from Canada to South America each year.

Diet

Most seagulls are obligate carnivores, sometimes supplementing their diets with bits of plant matter. They will often scavenge what they can from the surface of the ocean, beach, or land. These bold birds will even snatch food right out of a person’s hands.

What does the seagull eat?

The seagull eats a wide range of different foods. Its diet normally consists of fish, insects, earthworms, mollusks, rodents, small reptiles and amphibians, fruits and seeds, and even other birds and their eggs. They will prowl the same scavenging sites every day or fly high up in the air, diving down to pick off prey. However, they are not capable of diving down deep below the surface of the ocean.

Predators, Threats, and Conservation Status

Seagulls are highly versatile and adaptable birds. The vast majority are considered to be species of least concern by the IUCN Red List, although several species like the lava gull and the kittiwake are vulnerable to extinction. Climate change, pollution, loss of coastal habitat, overfishing, and deliberate hunting may be responsible for a downward trend in numbers.

What eats the seagull?

Baby seagulls and the eggs are often preyed upon by raccoons, minks, foxes, cats, and birds of prey. Adult gulls are less in danger of being eaten, but they’re sometimes preyed upon by particularly large and dangerous predators. Groups of seagulls will often mob a predator and strike with their wings and feet to drive it away.

Reproduction, Young, and Molting

The seagull’s reproductive season usually occurs in the early springtime after returning to the same site from the annual migration. They do show a tendency to take the same mate for life and may strengthen their bond through mutual feeding exercises. After mating, the female lays a clutch of up to three eggs per year. The parents will take turns incubating the egg for about a month, while the other parent hunts for food.

The parents will continue feeding the baby chicks until they’ve obtained their full-flight feathers a month or two after hatching. Many juveniles have a mottled brown appearance compared with the more solid colors of the adult plumage. It usually takes a few years to obtain full sexual maturity. Many species can live up to 30 years old; the oldest documented specimen was a 49-year-old white-headed gull.

Population

Seagull populations show an unfortunate downward trend in numbers. The American herring gull has an estimated population of some 246,000 breeding pairs, which is actually down from its peak. It’s estimated that numbers fell some 83% between 1966 and 2015. Altogether, millions of gulls can be found worldwide.
