Seabirds and Their Habitats
"Seabirds and Their Habitats (Planet Earth: Oceans & Seas)" refers to the diverse species of birds that live in marine environments and the unique ecosystems they inhabit. Seabirds, such as gulls, albatrosses, and puffins, rely on oceans and coastal regions for feeding, nesting, and breeding. Their habitats range from rocky cliffs and sandy shores to remote islands, playing crucial roles in the health and balance of oceanic ecosystems.

💡 Key Takeaways
- Identify major seabird groups and the habitats they rely on (coastal cliffs, islands, open ocean).
- Explain how habitat features—like nesting sites, currents, and productive foraging zones—shape seabird feeding and movement.
- Recognize key threats to seabird habitats, including plastic pollution, fisheries bycatch, oil spills, and invasive predators.
- Describe conservation and monitoring approaches used to protect seabird habitats (colony surveys, habitat restoration, protected areas).
❓ Frequently Asked Questions
What is a seabird?
A seabird is a bird that spends most of its life at sea, feeds at sea, and returns to land—often on remote coasts or islands—to breed.
Where do seabirds typically live and breed?
They spend much time on open oceans or coastal waters and breed in colonies on offshore islands, cliffs, beaches, or burrows.
What are common seabird feeding strategies?
Many feed at the surface, dive from the air to catch prey underwater, or plunge dive from a height; strategies vary by species.
How do seabirds cope with saltwater?
They have specialized salt glands to excrete excess salt and maintain water balance when drinking seawater.
Why are seabirds good indicators of ocean health?
Their feeding and breeding success reflect fish stocks, ocean temperature, and pollution levels, so changes signal ecosystem health.
