‘Like Finding a Unicorn’: Researchers Rediscover the Black-Naped Pheasant-Pigeon, a Bird Lost to Science for 140 Years

For a month the researchers had traversed slender mountain ridges, crossed and re-crossed rivers that roared through canyons cloaked in tropical forest, and endured bloodthirsty mosquitoes and leeches, all in search of something that probably didn’t exist. They had just hours left for searching before they had to leave Fergusson Island, off the east coast of Papua New Guinea. Expedition co-leader Jordan Boersma reckoned their chance of success was less than 1 percent.

Winded from a climb, he plopped down on a lush hillside to catch his breath and began looking through images on the camera traps he’d just collected, not expecting to find anything. “Suddenly I was confronted with this image of what at that time felt like a mythical creature,” says Boersma, a postdoctoral researcher at the Cornell Lab of Ornithology. “It was, without exaggeration, the most surreal moment of my life.” 

The camera’s display was tiny, but there was no mistaking the creature it showed: the Black-naped Pheasant-Pigeon, a species that hasn’t been documented by scientists since it was first described in 1882.

“To find something that’s been gone for that long, that you’re thinking is almost extinct, and then to figure out that it’s not extinct, it feels like finding a unicorn or a Bigfoot,” says John C. Mittermeier, director of the lost birds program at American Bird Conservancy and a co-leader of the eight-member expedition. “It’s extraordinarily unusual.” 

The stunning late-September rediscovery could not have happened without guidance from local hunters with intimate knowledge of the island’s forests, the researchers say, demonstrating the invaluable role of Indigenous communities in ongoing efforts to relocate species lost to Western science. With its existence confirmed, the Black-naped Pheasant-Pigeon is almost certainly the most endangered bird in New Guinea, which underscores the urgent need to protect its habitat on Fergusson, a rugged, 555-square-mile island that, while largely undeveloped, faces pressure from logging companies. “This is a huge discovery,” says Bulisa Iova, an expedition member and acting chief curator of the National Museum and Art Gallery in Papua New Guinea. “I have studied birds for many years, and to be part of this team to discover this lost species is a highlight for me.” Audubon.Org >> read more >>
