New Ireland: Three lost bird species rediscovered

During an expedition in Papua New Guinea, four young birdwatchers made an extraordinary discovery: In just 17 days, they documented three lost bird species in the mountain forests of New Ireland that had not been reliably recorded for years or even decades—the white-naped lory (Lorius albidinucha), the New Ireland friarbird

New Guinea: Two marsupials lost for 6,000 years rediscovered

In March 2026, an Australian research team led by zoologist Tim Flannery published two studies with surprising results: On the remote Vogelkop Peninsula in northwestern New Guinea, two marsupial species were found alive that had previously been known only from fossils approximately 6,000 to 7,500 years old. Such rediscoveries are

Rediscoveries in 2025: These animal species were considered lost or extinct

Species do not simply disappear just because no one has seen them for a long time. And they are just as little “saved” just because they suddenly reappear. Rediscoveries mark a narrow line between hope and uncertainty: they show that life can endure – often, however, only barely. In 2025,

Rediscovery: Rare kingfisher reappears after 13 years

The Bismarck kingfisher (Ceyx websteri) was considered lost for almost 13 years. Since the last confirmed record in 2012, the species had gone unobserved, raising fears that it might already be extinct. In May 2025, however, the species was confirmed again in Papua New Guinea: researcher John Lamaris documented a

Rediscovery off Papua New Guinea: The sailback houndshark is back

One of the rarest shark species in the world has reappeared off the coast of Papua New Guinea after more than 50 years: the sailback houndshark (Gogolia filewoodi). A WWF team led by marine biologist Jack Sagumai documented a total of six specimens near the mouth of the Gogol River

Mussau Triller: Lost Bird Species Rediscovered After 44 Years

The Mussau triller (Lalage conjuncta), last documented in 1979, was rediscovered in June of this year by Australian bird photographer Joshua Bergmark during a tour with a group of birdwatchers. This songbird species, part of the cuckooshrike family, is endemic to Mussau Island, located in the Bismarck Archipelago north of

Tongatapu rail

The only specimen is now lost Quite a few bird species of the past were described from only a single specimen that is now lost. One of them is the Tongatapu rail. Of this rail species (family Rallidae), historical reports and descriptions have survived that are based on observations and

Guam kingfisher: Reintroduction to Palmyra after extinction in the wild

The Guam kingfisher, last seen in the wild in 1986, is now poised to return to nature. After successful breeding in captivity, it is planned to release the offspring of this nearly extinct bird species on Palmyra Atoll. This remote atoll, located about 1,600 kilometers southwest of Hawaii, offers a

New beetle species with unique trait discovered on island

Australian researchers recently discovered a previously unknown species of scarab beetle (Scarabaeidae) in the insect collection of the Australian Museum in Sydney. The specimen in question, a female, was collected on January 30, 1979 on Lord Howe, a small island of only 14 square kilometers in the southwest Pacific. The
