Cambiando el rumbo para las aves marinas
More than two-thirds of our planet is covered by water — and almost every inch is visited by birds. Arctic Terns migrate from the Arctic to the Antarctic Ocean over the course of a year. The great albatrosses may circle the globe in a matter of days, gathering food for their chicks. Seabirds have a capacity for global travel that is only matched by humans. Sharing exquisite adaptations to life on the ocean, most seabirds spend a large part of their lives over, on, and under the open water, far from human populations — and all too often far from human thought.
As a group, seabirds are the world’s most endangered birds, with 70 percent declines in the last 60 years. Even birds we think of as common, like the gulls and terns we see on beaches and piers, are declining, while the island specialists, petrels, shearwaters, albatrosses, and others, are going fast.
These remarkable birds deserve our every effort to conserve them. Seabirds are champions of the bird world, with the largest wingspan, longest migration, and deepest dives among them. The oldest known wild bird is a Laysan Albatross banded in 1956.
ABC’s Marine Program and our partners seek to change the trajectory — to turn the tide for seabirds.
Soluciones a la vista
ABC’s Marine Program protects and restores seabird populations across the Western Hemisphere through innovation, partnerships, conservation planning, and direct action. We work with three central pillars for marine conservation:
- Safe Havens for Marine Birds: Finding the last strongholds and securing nesting places.
- Sustainable Seascapes: Ensuring marine birds and people have access to marine and terrestrial resources.
- Kinship: Increasing marine bird visibility through connections to human culture and activity.
Refugios seguros para aves marinas
The establishment of fenced or protected breeding colonies free of introduced predators is among the most effective of seabird restoration techniques and facilitates and enhances additional conservation measures such as social attraction and translocation. ABC is committed to finding and protecting areas appropriate for the long-term maintenance of communities of seabirds and other compatible species, and to collaborative work in invasive species removal, social attraction, and translocation.
For example, ABC and partners have built a predator-proof fence around seven acres within Kilauea Point National Wildlife Refuge in Hawaiʻi. More than 100 ʻUaʻu (Hawaiian Petrels) and ʻAʻo (Newell’s Shearwaters) have been moved there to establish a new colony.
For Critically Endangered species such as the Black-capped Petrel in the Caribbean, strategic conservation partnerships and resulting actions are essential. ABC has been a key partner in monitoring the few known nesting sites for the species in Haiti and the Dominican Republic. We now seek to restaurar islas en el Caribe a un estado que pueda volver a sustentar la cría de petreles de cabeza negra.
Protecting nesting sites works if you know where the nests are located. For some seabirds, we don’t have this basic information. Working with partners like Red de Observadores de Aves y Vida Silvestre de Chile (ROC), we seek nesting areas of mysterious seabirds like Pincoya Storm-Petrel, Magellanic Diving-Petrel, and Subantarctic Shearwater. We partner with the Búsqueda de aves perdidas to dig into enduring mysteries like the Jamaican Petrel and Guadeloupe Storm-Petrel, seabirds that are so rarely seen they may be extinct.
Paisajes marinos sostenibles
The commitment of fishers to the protection of marine bird populations is dependent on the economic viability of the tools we offer to reduce bycatch, the accidental capture of nontarget species. ABC is committed to the innovation and expansion of bycatch reduction tools and programs that are effective in working seascapes.
ABC has helped to develop techniques that reduce fisheries’ impacts on the Waved Albatross and other birds, for example, by limiting the amount of time fishing lines are exposed in the water, where they attract and hook seabirds. This simple technique is now being used in the small boat long-line fisheries in Ecuador.
Lights on land are beacons for humans at sea, indicating a safe passage or landmark. For marine birds, lights, power lines, and infrastructure are hazards. Large lights disorient the night-flying birds traveling from inland breeding grounds to ocean foraging areas, and power lines are collision hazards to fast-flying birds. We are working to reduce the impacts of night lighting and to establish national policies to protect all wildlife from unnecessary lights.
Other key linkages between seabirds and human use of the sea are the nutrient benefits brought to seabird nesting grounds from the open ocean. For thousands of years, people have used marine bird “guano” to enrich agricultural farmlands. Now we are coming to realize the benefits of the same nutrients in the restoration of islands, atolls, and coral reefs.
Parentesco
Mientras los marineros recorrían el mundo, las aves marinas siempre estaban cerca. Han formado parte de la exploración humana del océano desde sus inicios, símbolos de la comedia, la gracia y el desafío de la vida en el mar. Nos han enseñado geografía y nos han guiado de vuelta a casa. Nos ayudan a encontrar peces y a interpretar el clima. Y si bien las aves marinas son veneradas desde hace mucho tiempo por los marineros, son casi invisibles para la mayoría de las personas. Las aves marinas necesitan embajadores y narradores que las conozcan y sepan de los problemas que enfrentan.
ABC Marine Program fosters this kinship through art, sport, and human culture. Our work uses humor, adventure, and storytelling to bring the kinship between maritime peoples and seabirds forward as a fundamental part of marine conservation.
