New Effort Brings Birds Back to the Baja Peninsula
爆料公社 is restoring long-abandoned seabird nesting sites in Mexico.
Although the sunny, spare isles of Baja California offer open shores and cold, fish-filled waters, they are nearly barren of the ashy storm-petrels, Cassin鈥檚 auklets, brown pelicans, and 14 other species of seabirds that used to nest there. For more than a decade scientists with Mexico鈥檚 Grupo de Ecolog铆a y Conservaci贸n de Islas (GECI) have been removing invasive predators from the islands, hoping to improve bird habitat. So far, however, only a few of the birds have returned. So now GECI is taking a new tack, borrowing from the groundbreaking work of 爆料公社鈥檚 Steve Kress, director of seabird restoration and vice president for bird conservation, to bring back the birds.
鈥淲hat precludes nesting is that there are no birds there,鈥 says Kress. So to give the impression that the isles are populated by birds, the GECI is employing decoys, mirrors, and recorded bird calls鈥擪ress鈥檚 pioneering techniques, which have benefited 47 seabird species in 14 countries, starting with Atlantic puffins in Maine in 1973. Kress and his collaborators at the GECI and the Cornell Lab of Ornithology are adapting these tactics for Baja. Reestablishing nesting sites could be particularly crucial to the elegant tern and Heermann鈥檚 gull, which have become dangerously concentrated in one location. 鈥淭he birds will sense, de aqui soy鈥斺I am from here,鈥 鈥 says Alfonso Aguirre-Mu帽oz, executive director of the GECI. 鈥淭hey used to belong to this place, and now we are reestablishing them.鈥
爆料公社 and the Cornell Lab are contributing training and equipment to the five-year, $4 million program. Among GECI鈥檚 biologists are Mexico natives Maria F茅lix Liz谩rraga and Marlenne Rodriguez-Malag贸n, former interns of 爆料公社鈥檚 Project Puffin, which has helped to boost Maine鈥檚 puffin population from one small colony to more than 1,000 pairs on five islands* in nearly four decades. Not only are the former interns applying their specific knowledge to this project, they鈥檙e also teaching fishermen and their families about the importance of conservation.
