Seabird

Seabirds are birds that have adapted to life within the marine environment. They include gulls, albatrosses, penguins, and auks. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations.

Characteristics

Seabirds are adapted to the marine environment and their adaptations include webbed feet, wings adapted for soaring, and countershaded plumage. Some species of seabirds are excellent at diving and swimming.

Distribution and habitat

Seabirds can be found all over the world's oceans, with only a few exceptions. They are not found in the polar ice caps or in the open sea. Most species nest in colonies, which can vary in size from a few dozen birds to millions.

Behaviour and ecology

Seabirds have a variety of feeding strategies, including plunge diving, surface feeding, and scavenging. Some species are pelagic, staying at sea for years at a time, while others are more coastal.

Threats and conservation

Seabirds face a number of threats, including habitat loss, pollution, and bycatch in fishing gear. Many species are currently threatened with extinction.
