What are Seabirds & Their Adaptations?

Seabirds are a diverse group of birds that have adapted to life in the ocean. They spend most of their lives at sea, only coming to land to breed and raise their young. Found in every ocean, they play a vital role as health indicators for marine ecosystems.

  • Waterproof Feathers: Coated with oil to provide insulation and buoyancy.
  • Salt Glands: Specialized glands that excrete excess salt, allowing them to drink saltwater.
  • Specialized Beaks: Shapes are adapted to specific diets, from scooping fish to holding slippery prey.
  • Efficient Wings: Long, narrow wings for gliding (Albatross) or short, powerful wings for diving (Puffin).

How You Can Help Protect Seabirds

πŸ’‘Our Expert Tip

The best way to enjoy seabirds is from a respectful distance, especially near nesting colonies. Use binoculars to get a closer look without causing disturbance. Getting too close can stress the birds, causing them to fly off and leave their eggs or chicks vulnerable to predators. Letting wildlife be wild is the greatest help you can offer.

5 Key Actions to Make a Difference:

  1. Reduce Plastic Use: Plastic bags, bottles, and packaging often end up in the ocean, where seabirds mistake them for food or get entangled.
  2. Dispose of Fishing Line Responsibly: Discarded fishing line is a deadly trap for seabirds. Always cut it into small pieces and dispose of it in a secure bin.
  3. Choose Sustainable Seafood: Overfishing depletes the food sources seabirds rely on. Use seafood guides to make responsible choices that protect marine ecosystems.
  4. Keep Beaches Clean: Participate in beach cleanups or simply pick up trash whenever you visit the coast. Every piece you remove is one less hazard for marine life.
  5. Support Conservation Organizations: Donate to or volunteer with groups that work to protect marine habitats, rescue oiled birds, and advocate for stronger environmental policies.
