The first seabird-like creatures that we know of were the Hesperornithes, early flightless birds that evolved during the Cretaceous period, at the end of the “age of the dinosaurs.” These birds propelled themselves underwater with their feet. Among bird species alive today, large grebes, such as the Great Grebe, may hold the closest resemblance to ...
Seabirds tend to be long-lived, with many producing relatively few chicks (only one each year or even every other year in some species), for which they invest much time and resources. To raise these chicks, most seabirds form pairs that may mate for life, with both males and females contributing to raising offspring. Often, seabirds nest in breedin...
Seabirds' migratory behavior varies. Some species stay relatively close to home, remaining in feeding areas within a few hundred miles of their nesting colonies. Others, however, are among the most impressive long-distance migrants in the bird world. Arctic Terns, for example, move between the Arctic and Antarctic each year, a round-trip journey of...
Albatrosses, petrels, and storm-petrels: These “tube-nosed” birds have an unusually acute sense of smell, honing in on decaying marine life, prey species, and a chemical called dimethyl sulfide, which is produced by phytoplankton and can indicate a particularly rich foraging area. The world's largest seabird, the Wandering Albatross, with a wingspa...
As a group, seabirds are among the world's most endangered birds — nearly one-third of all seabird species are listed under a threat category by the International Union for Conservation of Nature (IUCN). Their declines are due to a number of factors, including the following: Invasive species:Many seabird species evolved on distant islands without p...
American Bird Conservancy (ABC) works in a variety of ways to safeguard seabirds. We protect breeding habitats and help restore them by removing invasive predators. We also work to establish new protected breeding sites. Among other projects, ABC and partners have built a predator-proof fence around seven acres within Kilauea Point National Wildlif...
Policies enacted by the U.S. Congress and federal agencies have a huge impact on seabirds. You can help shape these rules for the better by urging lawmakers to prioritize birds and bird-friendly measures. To get started, visit ABC's Action Center. Plastics pose a deadly threat to seabirds around the world. You can help seabirds by reducing your dai...

Nearly half (47%; 52% of those with known trends) of seabird species are known or suspected to be experiencing population declines (Figure 2).
As a group, seabirds are among the world's most endangered birds. For example, 15 of 22 species of albatross are threatened with extinction. These remarkable birds deserve our every effort to conserve them. Many seabirds, like Waved Albatross, mate for life and can live for 60 years or more. Sadly, few reach such old age.
Apr 20, 2019 · The latest assessment of the global threat status of seabirds, using the International Union for Conservation of Nature (IUCN) Red List criteria, revealed that 31% of all seabird species are globally threatened (i.e. Critically Endangered, Endangered or Vulnerable; 110 of 359.
