（24-25高一下·江苏连云港·期中）Every day at sunrise on the small French Polynesian island of Rimatara, Tiraha Mooroa goes for a run with Koha, the dog. Koha has an important job: to sniff out (嗅出) and kill any black rats he can find. Koha is the island’s only defense against the invasive rats. Keeping the island rat-free is vital: the rats, which arrive via boats and cargo ships (货船), are the single biggest threat to native birds of the Pacific Islands, including the Rimatara lorikeet. The beautiful bird is critically endangered—only 1,500 remain in the wild, and a third of the entire population lives on tiny Rimatara island. Now, of the 118 islands in French Polynesia, Rimatara is one of only three without the rats.
The lorikeet was once widespread in the South Pacific. By the 18th century, however, it had already been hunted to near extinction by the Polynesians, who prized the bird’s red feathers for making headdresses. By 1900, the island’s queen, Temaeva V, banned hunting of the birds, effectively preserving the remaining population. Since the 1990s, however, the lorikeets have faced rising threats.
Socio-environmental researcher Samuel Ravatua-Smith heads up a nest observation program, launched by the conservation association Rima Ura, to better understand the lorikeet and its population decline. The program monitors all lorikeet nests on the island with Bluetooth-enabled cameras. Ravatua-Smith’s face falls as he watches the footage (镜头). “The videos confirm that after the visit of a white-tailed tropicbird, the two hatchlings are no longer in the nest. The while-tailed tropicbird may be targeting and taking over lorikeet nests because of its own habitat loss,” Ravatua-Smith says.
It’s an important finding that brings Rima Ura another step closer to saving the lorikeet. This year, close to 100 new houses are set to be built to provide housing for residents in need. The clearing and construction may end up encompassing (涉及) more than half of the island. Rima Ura works to educate residents of Rimatara about how they can help protect the lorikeet, for instance encouraging locals to plant more fruit trees around their houses. Members of Rima Ura who live on the island also mark nesting trees and participate in reforestation initiatives.
