Ocean Birds

Ocean birds are types of birds that lives mostly in the sea. They are also called seabirds or marine birds. These birds live by feeding themselves sea creatures that they hunt at the surface of the open sea. Some of the seabirds even go diving to the ocean to gather their food.

Not all of the seabirds live in the marine environment all year long. Some of ocean birds are known to migrate very far. They even fly almost to the other side of the Earth. Thus, they are known to be able to endure great flight.

Living in Colonies

These birds are known to form great colonial living among the same species. They live in flocks and build their nests in flocks as well. The colony of seabirds can have up to one million birds in it. The nesting period is also done in colonies.

Nesting in colonies is mostly done in an island where it is far from outside disruption. However, in the events where there are threat against their nests, the colonies will be quick to defend them.  As a result, nesting season is more likely to be successful. These are advantage of living in bird colonies.

Types of Ocean Birds

Threat and Conservations

Ocean birds have benefited fishermen as the existence of seabirds show potential fishing site. The birds also benefited from the leftover fishes and other sea creatures that were thrown away by fishermen so they can be consumed by the marine birds.

However, there are also negative impacts to the birds as the existence of fishermen can harm their nests. Humans hunt seabirds and their eggs for exploitation and that is a threat to the existence of sea birds themselves.

Other threat also come from the highly pollute oceans. Dangerous pollutant are result of human irresponsibility such as the leak of oil to the oceans. These dangerous chemical not only damage sea creatures, but also sea birds that lives and feed on the open ocean.

Nowadays, there governmental and non-governmental institutions that are campaigning for the conservation of ocean birds. From projects in the United Kingdom, New Zealand, to the United States, there are campaign on increasing seabirds’ morality by using the proper fisheries technique.

Marine birds are a beautiful species of birds that are important for the ecosystem of the marine environment. The species of birds can be conserved by using proper fishing technique and stopping the illegal exploitations of ocean birds and their eggs.
