If you’ve ever watched birds along the coast, you’ve probably noticed they behave a little differently from backyard birds. Sea and shore birds are full of fascinating adaptations that help them survive in windy, salty, ever-changing environments. Here are some amazing (and sometimes weird!) things to look for next time you’re near the water:
Before we dive in: If you’re an educator planning to teach sea and shorebirds, great learning resources are key to deepening understanding! I think you and your students will love my complete Sea and Shorebirds Unit (plus you’ll support my blog with your purchase! ❤️)
1. Some Birds Nest Right on the Ground
Many seabirds, like terns, don’t build elaborate nests in trees. Instead, they create a simple “scrape”—a shallow depression in sand or gravel. It might not look like much, but it helps keep eggs from rolling away and provides just enough shelter to blend into their surroundings.
2. Albatrosses Are Masters of the Wind
Albatrosses have some of the largest wingspans of any bird on Earth—some stretching to about 10 feet! These wings allow them to glide effortlessly on ocean winds, sometimes traveling miles without flapping much at all.
3. Skimmers Fish in a Totally Unique Way
Skimmers have one of the strangest feeding strategies in the bird world. They fly low over the water with their lower bill slicing through the surface. When they bump into a fish, SNAP!—they quickly grab it. Their uneven bill (longer on the bottom than the top) makes this possible.
4. Cormorants Have to Dry Their Wings
Unlike ducks, cormorants don’t have fully waterproof feathers. After diving for fish, their feathers get soaked. That’s why you’ll often see them perched with wings spread wide—air-drying in the sun and wind before their next dive.
5. Some Birds Can Drink Saltwater
Living by the ocean presents a salty challenge—but many seabirds have a special solution. Birds like gulls have salt glands near their eyes that remove excess salt from their bodies. The salt is then expelled through their nostrils—kind of like sneezing out seawater!
6. Shorebirds Are Long-Distance Migrants
Many shorebirds are incredible travelers. Some species migrate thousands of miles each year between breeding and feeding grounds. For example, the Arctic tern migrates between the Arctic and Antarctic!
7. Their Beaks Are Built for Specific Jobs
Take a close look at different shorebirds, and you’ll notice a wide variety of beak shapes. That’s because each one is adapted for a specific feeding style. Some probe deep into the sand for worms, while others pick tiny creatures off the surface. These specialized tools help reduce competition and allow many species to share the same habitat.
If you want to explore bird beak adaptations further, try out this bird beak educational activity for the classroom. I’ve also created printable worksheets and handouts for this activity.
Sea and shore birds may live in harsh environments, but their unique adaptations make them perfectly suited for life along the water. Next time you’re at the beach or coastal wetland, take a moment to watch them—you might just spot one of these amazing behaviors in action!
