What are the common characteristics of seabirds?

Seabirds are birds adapted to life at sea. They have feathers that are dark on top and lighter underneath. Apart from that, their nostrils are enclosed in tubes, hence can smell food several miles away. However, what makes them easily adapted to sea life is the waterproof feathers, fat layers, and ability to desalinate themselves.

What is the role of seabirds in the ecosystem?

Seabirds shape coastal ecosystems in three distinct ways. They carry marine nutrients from the deep sea to the islands and reefs, drop layers of organic matter at their colonies (fertilizing underdeveloped soil), and disperse seeds. Unfortunately, they are often overlooked and their habitats and food sources are exploited by humans.

Can seabirds swim?

Seabirds are well adapted to life on air, water, and even land. So they can swim, dive, float, and fly. This ability to swim is because they have waterproof feathers, fat layers to keep warm in cold water, and can desalinate themselves. They can also hold their breath underwater for three to ten minutes.

How long do birds typically live?

Birds typically live between 4 to 100 years depending on the species itself. Birds age differently than other animals as once they reach their adult plumage, they are almost impossible to age. It is believed that they accomplish this by the oxygen and protein process associated with their metabolism.

How do birds sleep?

Birds sleep by finding either a secluded branch or tree cavity to sleep on. Before sleeping they fluff their down feathers beneath their outer feathers and turn their head to face backward. Then they tuck their beak into their back feathers and close their eyes to sleep.

Why do birds migrate?

Birds may migrate for long distances, medium distances, short distances, or not at all depending on their needs. Birds typically migrate to go from an area of low resources to another area of high resources. They often look for areas with food or nesting locations. These needs may also vary by season as birds migrate from the north to the south once the winter season begins.

How do animals adapt to the coast?

Animals adapt to the coast by adjusting to living in salty water as well as being able to withstand being covered or uncovered by the tide. Further coastal adaptations also include being able to hide or escape quickly from predators, finding food, and staying in a safe place as the tides move.

Why are coasts important for wildlife?

Coasts are important for wildlife because they serve as nesting grounds for species of sea turtles as well as are habitats for animals like beach mice. Coasts are also important foraging areas for migratory shorebirds. Coasts are important as they are used in cohesion by all species of animals.

How does coastal erosion affect animals?

Coastal erosion affects animals and humans as it causes sea levels to rise, flooding, as well as stronger waves. Coastal erosion also causes the gradual loss of land that is important to many animals. Coastal erosion is when a portion of land is lost within a shoreline by either natural events or manmade decisions.

How do animals survive in estuaries?

Animals survive in estuaries by adapting to the harsh conditions of their habitat. Estuaries either have salt water or fresh water. Animals survive by adapting to live in the different types of conditions and remaining in the regions of the estuaries where they are most comfortable and have consistency.

Why do fish lay eggs in estuaries?

Fish lay eggs in estuaries because these habitats offer a great amount of food availability for the development of young fish while also providing protection from predators. Estuaries are often used as breeding grounds by many species of fish due to these factors and are considered highly valuable.
