Scientists Made a List of Lost Birds and Now They Want Us to Find Them

A major goal of the list is to persuade bird watchers and others to look for these birds as they go out into the field, and to bring back evidence the birds have not gone extinct.

People have searched for lost birds for decades. But the process was formalized in 2020 by the conservancy, in partnership with two other groups, Re:wild and BirdLife International, as the Search for Lost Birds project.

Researchers from the groups published a

with a definitive list of birds that need finding. They scoured tens of millions of photos, videos and audio recordings in birding databases such as iNaturalist and xeno-canto. The study concluded that there are 144 species of bird lost to the scientific world but that may still exist.

“Through more exposure in global ornithological and birding networks, there’s great potential to learn more about birds that are poorly known and highly threatened,” said Cameron Rutt, the lead author of the paper who coordinated the project for the ********* Bird Conservancy until recently.

Once the birds are documented, experts analyze how they can be protected and studied. Since the rediscovery of Santa Marta sabrewings, for instance, researchers have been studying the bird’s habitat needs and biology and

on their findings.

They have identified five small populations of the birds, about 50 individuals, in a small forested valley on one fork of the Guatapurí River in Colombia. The sabrewing population is a case of micro-endemism, experts say, a species restricted to one very small, specific place. It’s considered critically endangered.

Finding a species prompts a new list of challenges. What is the best way to protect it, whether from storms, a changing climate or crowds? Esteban Botero-Delgadillo, director of conservation science for SELVA, a Colombian conservation organization said he and others worried “if this news came out there would be a lot of bird watchers and people.”

For that reason, he added, they “were very vague about where it was for more than a year.” The bird is on Indigenous land which makes management more complicated.

********* can be a danger in the habitats of some lost birds. The rediscovery in 1999 of a small cluster of yellow-eared parrots, striking green birds with yellow markings in western Colombia, led to the creation of a reserve. The population grew to thousands.

In 2021, the environmentalist who nursed the population to healthy numbers, Gonzalo Cardona, was shot and ******* by an unknown ********* gang, his body ******* in a shallow grave. Dr. Botero-Delgadillo said his team too must be wary in the field.

Another recently found bird on the top 10 list is the ******-naped pheasant pigeon. The chicken-size bird was found in a remote region of Papua New Guinea in 2022 after not having been documented in 126 years.

Though the existence of a bird may not have been documented by science for a long time, that doesn’t mean it is lost to local people. To find the pheasant pigeon, the most endangered terrestrial bird in Papua New Guinea, researchers traveled to villages where the bird had last been seen.

Among those was John C. Mittermeier, founder of the Search for Lost Birds Project. “People who live there are largely subsistence farmers, fisherman and hunters and so they know the land and the wildlife really, really well,” Dr. Mittermeier said. “We asked them whether they had seen this species,” whose local name is auwo.

One day one of the birds strutted in front of a camera trap that had been set up.

“Seeing those first photos of the pheasant pigeon felt like finding a unicorn,” Dr. Mittermeier said. “It’s the kind of moment you dream about your entire life as a conservationist and bird watcher.”

Three species in North America are considered lost. Best known is the ivory billed woodpecker. Its last universally accepted sighting in the ******* States was in Louisiana in 1944. It was spotted again in Cuba in 1987. There has not been a confirmed sighting since. Because of grainy videos of what could be the bird, the U.S. Fish and Wildlife Service has not declared the bird extinct.

The other two birds in North America are the Eskimo curlew and the Bachman’s warbler.
