Introduction
Have you ever looked out over the ocean and noticed a bird soaring gracefully above the waves, resembling a seagull but with subtle differences? You’re not alone! Many people mistake certain Seabird Related to a Gull, but in reality, gulls have several close relatives that share their appearance and habitat while exhibiting unique behaviors and characteristics.
I remember sitting on a pier one summer afternoon, watching a flock of birds dive into the ocean. At first, I thought they were all seagulls, but then I noticed a few with sleeker bodies and sharper beaks, plunging headfirst into the water. A local birdwatcher beside me smiled and said, “Those are terns—not gulls!” That moment sparked my curiosity about these fascinating seabird relatives. In this detailed article, we’ll explore their features, behaviors, and how they play a crucial role in marine ecosystems. If you love seabirds and want to observe them up close, consider investing in high-quality binoculars for birdwatching, which enhance every detail of these stunning creatures.
Understanding Gulls and Their Relatives
Gulls belong to the family Laridae, a group of seabirds that includes not only true gulls but also terns, skimmers, and kittiwakes. These coastal birds share common ancestors and have adapted to life near ocean shorelines, rivers, and even inland water bodies. While they might look alike at first glance, each of these seabird species has evolved distinct features that set them apart.
If you’re passionate about seabird photography or birdwatching, a field guide to seabirds is an essential tool to help you identify and learn about different species.
The Tern – A Gull’s Closest Cousin
One of the most well-known relatives of gulls is the tern. Terns belong to the same Laridae family but differ in several ways:
- Size & Shape: Terns are typically smaller and more streamlined than gulls. Their bodies are slender, and they have long, pointed wings that help them fly with incredible agility.
- Beak Shape: Unlike gulls, which have thicker beaks suited for scavenging, terns have thin, sharp beaks designed for catching fish mid-dive.
- Flight Style: Terns are known for their breathtaking aerial acrobatics. They often hover before plunging into the water to catch fish, whereas gulls are more likely to scavenge or catch prey near the surface.
- Coloration: Most terns have a black cap on their head, a white body, and light gray wings, making them distinct from gulls.
The Arctic Tern – A Migration Champion
The Arctic Tern (Sterna paradisaea) is particularly remarkable. It holds the record for the longest migration of any bird, traveling up to 44,000 miles annually between the Arctic and Antarctic! Imagine a bird that experiences two summers each year—what an incredible feat! A friend of mine who once tracked Arctic Terns in Iceland told me how these birds seemed to disappear into the sky, only to reappear months later on another continent. Their resilience and endurance are nothing short of astonishing.
To track migrations like experts do, you can use GPS bird trackers, an amazing tool that lets you follow avian journeys across the globe.
Other Seabirds Related to Gulls
While terns are the most recognizable relatives of gulls, there are other lesser-known but equally fascinating seabirds that share an evolutionary link with gulls.
1. Skimmers – The Unique Hunters
Skimmers (Rynchopidae) are fascinating seabirds closely related to gulls, but they have an unusual adaptation:
- Beak Structure: Their lower mandible is longer than the upper one, allowing them to skim the water’s surface and scoop up fish.
- Hunting Method: Unlike gulls, which primarily scavenge or hunt in a conventional manner, skimmers fly low over the water with their beaks open, slicing through the surface to catch unsuspecting fish.
- Nocturnal Activity: Some species of skimmers prefer to hunt at dusk or night, taking advantage of calm waters and reduced competition.
Want to experience the beauty of nocturnal seabirds? Night-vision binoculars are perfect for observing skimmers in action after sunset.
2. Jaegers (Skuas) – The Aggressive Predators
Jaegers, also known as skuas, are seabirds that take hunting to another level. Unlike gulls, which are opportunistic feeders, jaegers are aggressive predators and skilled kleptoparasites (meaning they steal food from other birds!).
- Appearance: They look somewhat like larger, darker gulls with powerful wings and sharp beaks.
- Hunting Behavior: Jaegers chase other birds mid-flight, forcing them to drop their catch, which they then snatch up for themselves.
- Adaptation: While gulls thrive in urban areas, jaegers are more commonly found in remote coastal regions and open seas.
A wildlife photographer once shared a story of watching a jaeger relentlessly chase a tern over the ocean, twisting and turning until the exhausted tern finally let go of its fish. “It’s like watching a pirate rob a merchant ship in the sky,” he laughed. Capture such breathtaking moments with a high-zoom camera for birdwatching!
3. Kittiwakes – The Cliff Nesters
Kittiwakes (Rissa tridactyla and Rissa brevirostris) are another group of seabirds closely related to gulls, but they have unique nesting habits and appearances.
- Nesting Behavior: Unlike most gulls that nest on beaches or near human settlements, kittiwakes prefer steep, rocky cliffs.
- Smaller, Daintier Features: They have shorter legs than gulls and a more delicate appearance.
- Diet: Kittiwakes primarily feed on small fish, which they catch while flying over the ocean.
On a trip to Alaska, I saw thousands of kittiwakes nesting on the cliffs of a fjord. Their constant chatter filled the air, and as I watched, I saw a young chick take its first leap off the ledge. For a moment, it looked like it might plummet straight down—but at the last second, its wings caught the wind, and it soared. It was breathtaking!
The Role of Gulls and Their Relatives in the Ecosystem
Gulls, terns, skimmers, jaegers, and kittiwakes all play crucial roles in maintaining the balance of marine ecosystems.
