(Washington, D.C., May 30, 2019)Today, American Bird Conservancy (ABC) announced awards totaling $100,000 to restore important seabird nesting colonies in Mexico, Peru, Chile, and the Dominican Republic. The awards will leverage additional matching funds, putting a total of $243,000 on the ground for direct conservation. Through this effort, ABC and partners are investing in the future of some of the Western Hemisphere’s most imperiled seabirds, including the Townsend’s Shearwater, Guadalupe Murrelet, Ashy Storm-Petrel, Townsend’s Storm-Petrel, Peruvian Diving-Petrel, and Black-capped Petrel. These species are listed as Endangered and Critically Endangered by the International Union for Conservation of Nature. Some of the nesting sites where the projects will occur are globally recognized for their unique biodiversity through the Alliance for Zero Extinction.

These restoration grants, the first of their kind offered by ABC, address an urgent need for increased investment in capacity for seabird restoration, particularly in South America, where 38 globally threatened seabirds occur amidst unaddressed and growing threats, such as introduced predators.

Support for local initiatives is a key focus of these awards. “We are pleased to provide funds to dedicated local conservationists, many of whom are the only individuals or groups working to protect seabirds in their countries,” says Hannah Nevins, ABC’s Seabird Program Director.

Awards include:

  • MexicoYuliana Bedolla and Federico Mendez of Grupo Ecología y Conservación de las Islas (GECI) will lead a project focused on restoration and monitoring on seven Mexican islands to protect four globally threatened seabird species. GECI is globally recognized for its expertise in eradicating nonnative species from islands. The project will benefit the Critically Endangered Townsend’s Shearwater and Endangered Guadalupe Murrelet, Ashy Storm-Petrel, and Townsend’s Storm-Petrel. Social attraction and artificial burrows will be used to attract birds to nest sites protected from nonnative predators.
     
  • Peru – This project will support conservation of the Endangered Peruvian Diving-Petrel by providing baseline information on nonnative rodent impacts at the birds’ island nesting sites. It will also create a framework to communicate the need for conservation action, including invasive rodent eradication, on two important seabird islands off the Peruvian coast in the Reserva Nacional de Paracas. This effort will be led by Dr. Carlos Zavalaga of Universidad Científica del Sur, Marine Ecosystems Research Unit - Seabird Group, and Dr. Joanna Alfaro of ProDelphinus, in Lima, Peru.
     
  • Chile – Social attraction techniques that broadcast bird calls to simulate the sounds of an active colony will be used to attract Endangered Peruvian Diving-Petrels to the island of Chañaral, which was formerly home to the world’s largest nesting colony of the species, but is now empty. An earlier project to eradicate habitat-damaging nonnative rabbits has made the island safe for the birds to return. This work will be led by Coral Wolf of Island Conservation in collaboration with local partner Dr. Claudia Fernández Zamora of Universidad Católica del Norte, Coquimbo, Chile.
     
  • Dominican Republic – A team, led by Ernst Rupp of the conservation nonprofit Grupo Jaragua and Dr. Yvan Satgé from the South Carolina Cooperative Fish and Wildlife Research Unit at Clemson University, will work in the Sierra de Bahoruco to protect the few known nesting sites of the Endangered Black-capped Petrelby controlling nonnative predators.

“For species such as the Black-capped Petrel, few nesting sites have been found, so it is critical to protect each and every known site. The clock is ticking loudly for this species. Adult birds return every year to the same burrow and are subject to an onslaught of threats — human disturbance, agricultural encroachment, forest fires, and nonnative predators,” says Nevins.

Seabirds are among the most imperiled groups of birds. About one-third of seabird species are in decline worldwide due the above-mentioned threats, along with sea-level rise, reduction of prey due to overfishing, and fisheries bycatch. Most seabirds nest on or under the ground in burrows, where they are especially vulnerable to nonnative predators, including feral cats, mongooses, rats, and mice.

“Through these awards, ABC seeks to promote the kind of coordinated, large-scale efforts needed to conserve seabird nesting colonies,” added Dr. George Wallace, ABC’s Threatened Species Conservation Officer. “The goal is to ensure that our children will see these magnificent species persist into the next century and beyond.”

(Washington, D.C., April 30, 2013) An international team of scientists from Chile, the United States, and Canada are mapping and timing the travels and activities of the imperiled Pink-footed Shearwater (PFSH) to better understand the habits and habitats of this species during their transequatorial migrations. This research will help shape conservation actions to help this species rebound from population declines resulting from a suite of impacts, both on the breeding colonies and at sea.
The project is a collaborative effort of individuals from the conservation organization Oikonos Ecosystem Knowledge, Chile’s Corporación Nacional Forestal (CONAF), Environment Canada’s Canadian Wildlife Service, the U.S. Geological Survey (USGS), Hawai’i Pacific University, American Bird Conservancy, and the National Fish and Wildlife Foundation.

The project involves the real-time satellite tracking of six breeding shearwaters. Four of these are still foraging near the Chilean mainland during the day and returning at night to feed chicks waiting in their burrows on Isla Mocha; two have already begun their long migration to spend the austral winter off Peru or off the west coast of North America. The transmitters are expected to continue functioning through this fall, when the birds return to Chile to begin the next breeding season. USGS, with support from the U.S. Bureau of Ocean Energy Management and collaborators, plan to deploy 10 more units this summer off California.

“The satellite tracking technology allows us to map, within a few kilometers, the locations of the birds,” said Josh Adams, a biologist with the USGS Western Ecological Research Center, who specializes in tracking seabirds at sea. “We are gathering data about where the birds go and about how long they spend in key foraging areas.”
When integrated with oceanographic conditions and wind patterns, these data can provide information about the birds’ preferred foraging habitats and the dynamics of their movements. In addition, this information may be evaluated in the context of defined ocean zones, such as sovereign Exclusive Economic Zones, marine protected areas, or active fishery zones, to elucidate where shearwaters may be most at risk of mortality or injury from interactions with human activities.

“The threats faced by this species at sea are poorly known,” said Valentina Colodro, a biologist with Oikonos Ecosystem Knowledge who attached the transmitters to the birds in early April, with assistance from CONAF park rangers on Isla Mocha. “Satellite tracking data will shed light not only on current at-sea threats but also provide preliminary information about the relationship of these birds with conditions at sea that may respond to variation in marine climate.”

The range of the Pink-footed Shearwater outside the breeding season extends along the length of the Western Hemisphere and traverses the territorial waters of 13 countries, from Chile to Canada. In contrast, the breeding range of the Pink-footed Shearwater includes only three Chilean islands: Isla Mocha, Robinson Crusoe, and Santa Clara in the Juan Fernández Islands. The species’ total breeding population is estimated at only about 28,000 pairs, more than half of which nest on Isla Mocha. Their diet consists of fish, squid, and crustaceans.

The species is threatened by predation by non-native mammals, such as feral domestic cats and rats, hooking or entanglement in fishing gear, habitat destruction at breeding colonies, and the illegal harvesting of the chicks by human inhabitants of Isla Mocha. The Pink-footed Shearwater is designated as globally “Vulnerable” by the International Union for the Conservation of Nature, is a focal marine species of common conservation concern for the Commission for Environmental Cooperation, and is listed as Endangered in Chile and Threatened in Canada. In addition, the species is a candidate for inclusion in the international Agreement for the Conservation of Albatrosses and Petrels.
