Aug 23, 2024 · Seabirds are birds that spend some part of their lives living on and feeding in the sea. They include petrels, albatrosses, shearwaters, penguins, gannets, boobies, tropicbirds, frigatebirds, shags (or cormorants), auks, skuas, gulls, terns and noddies.
Sep 22, 2021 · Well, not quite—there’s no concrete definition of what makes a bird a seabird. But there are a few characteristics that ornithologists (bird scientists) and bird watchers alike use to define them. Generally speaking, seabirds are birds that are adapted for life in a marine environment.

Because each species evolved to survive in its own unique environment, seabirds exhibit a wide range of physical characteristics. The ten foot wingspan of a Wandering Albatross, for example, bears little resemblance to the short, flightless wings of a Rockhopper Penguin. In spite of such differences, however, most seabirds do have several physical ...
The majority of seabirds base their diet upon marine life, and many, such as albatrosses, often fly great distances to obtain a meal. Common sources of food for seabirds include: • Fish • Squid • Crustaceans • Krill • Plankton Some birds, such as frigatebirds and gulls, will also engage in scavenging or stealing food. In some cases, they will even ...
Seabirds typically wait longer than other types of birds do to have offspring. In addition, they produce fewer chicks at a time, sometimes laying as little as one egg a year. Once chicks hatch, however, both parents tend to devote a large amount of time to care for their young, sometimes flying with them for months over the sea. These parents are a...
The overwhelming majority of seabirds form nesting colonies, with many of the members returning for breeding to the same area in which they themselves were hatched. Since most seabirds are migratory and may travel long distances, their ability to remember and return to a specific birthplace is remarkable. While colonies often contain only members o...
Seabirds typically live near saltwater, although the amount of time they spend there is highly variable. Some seabirds spend most of their lives inland, while albatrosses may remain on or over the ocean for several years. Most, however, live close enough to saltwater that they can easily feed on fish and other sea life. Seabirds exist near oceans a...
The greatest threats to seabirds are: • Overhunting by humans for feathers, eggs, and other products, which caused the extinction of such species as the Great Auk • Introduction by humans of predators into previously safe nesting areas • Destruction of seabird habitats by factors like oil leaks and pollution • Ecologically disruptive activities, su...
May 24, 2012 · Here is a general overview of 10 characteristics of seabirds (birds that spend most of their life out at sea), shorebirds (migratory birds that scurry along the shore looking for food), and wading birds (taller birds that wade in wetlands for their food).
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. 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.
Everyone who has visited the coast is familiar with gulls, those graceful, long-winged birds that throng the beaches and harbours and boldly beg for scraps. The gulls are a family of birds that live mainly at sea, either along the shore, or out in the ocean itself.
