The first is the black-naped pheasant-pigeon. The word nape refers to the back of the neck, and this bird does have a black neck. It’s a dark blue-black all over, in fact, with reddish-brown wings, a red bill, red eyes, and long yellow legs. It looks almost identical to the other three species of pheasant-pigeons known, although some scientists think they’re subspecies. Those three are the white-naped, the green-naped, and the grey-naped pheasant-pigeons, and if you’re wondering if the spot of color on the back of the neck is the easiest way to tell these birds apart, you are exactly right. All four species are native to parts of New Guinea or small islands nearby. Pheasant-pigeons look a lot like pheasants and are about the size of a chicken, although they’re actually pigeons. They live in forests and eat seeds and fruit, and while they can fly they spend almost all of the time on the ground. We don’t know a whole lot about them because they’re so secretive and hard to spot in the wild, although the white-naped and green-naped birds are sometimes kept in zoos. In the case of the black-naped pheasant-pigeon, all scientists knew about it was from two specimens collected in 1882. It hadn’t been seen since...until September of 2022. A team of scientists visited Fergusson Island off the east coast of Papua New Guinea in September, as part of a worldwide collaboration of scientists called The Search for Lost Birds. This is similar to the Search for Lost Frogs that has been active for over a decade, discovering lots of new amphibians and rediscovering even more. The 2022 search was actually a follow-up to a 2019 expedition that had failed to find the bird, although it did make other discoveries. In 2022, the team brought more people and equipment, determined to make the best effort possible to find the black-naped pheasant-pigeon. They consulted with local hunters to find the best places to search, and talked to lots of residents to see if anyone had seen one, and spent day after day hiking through forested mountains. For weeks they had no luck. Then, in a remote mountain village, they finally met some people who were familiar with the bird. One man led them to the right part of the forest and they set up camera traps, but at that point they only had a few days left before they had to leave the island. When they checked the pictures captured by the camera traps, though, they’d found it! Two of the cameras had taken pictures and video of what were definitely black-naped pheasant-pigeons, and since the cameras were several kilometers apart the pictures were probably of different individuals. The black-naped pheasant-pigeon wasn’t extinct, which means it can be protected. Habitat loss, especially from commercial logging, and feral domestic cats are the two main threats to birds in the area. The other bird we’re going to talk about today hasn’t been seen in even longer: 119 million years, in fact. The article about this fossil was only released a few days ago as this episode goes live. You can check the show notes for links to this article and a good one about the pheasant-pigeon too. Paleontologists discovered the bird’s fossil remains in northeastern China, in fossil beds that contain incredibly well-preserved animals and plants. The Jiufotang Formation in China dates to the early Cretaceous, between about 122 and 119 million years ago, and researchers think it’s from an area that was once a shallow lake surrounded by forests. Every so often, a nearby volcano would erupt and the resulting ash would fall into the lake, causing anoxic conditions that helped preserve animals that died and sank into the mud at t
