Biologists Rejoice as Extremely Rare Guam Kingfishers Lay Their First Wild Eggs in Nearly 40 Years
A colorful bird that’s been extinct in the wild for nearly 40 years has been introduced on a new island in the Pacific Ocean—and the population has even started laying eggs.
With help from conservationists, the Guam kingfisher (Todiramphus cinnamominus) seems to be settling in on Palmyra Atoll, a remote circular chain of 26 islets located halfway between Hawaii and American Samoa.
Biologists are cautiously optimistic about the species’ future after discovering eggs in a nest roughly 12 feet off the ground on March 31.
The nine kingfishers hatched in various zoos and facilities across the United States, then were transported to the Sedgwick County Zoo in Wichita, Kansas, to be hand-reared by keepers. Once they were old enough, they made the 4,500-mile flight to a Nature Conservancy research station on Palmyra Atoll. They spent about a month getting acclimatized before researchers outfitted them with radio trackers and set them free.
The birds’ long journey—both literally and figuratively—makes the recent discovery of wild eggs all the more impressive to biologists.
“These birds were raised in captivity until last year,” says Martin Kastner, a biologist working with the Nature Conservancy and the Zoological Society of London on the Guam kingfisher reintroduction project, to Public Radio Guam’s Mia Perez and Naina Rao. “Now they’re foraging, nesting and even laying eggs on their own. It’s an incredible step forward.”

Population of endangered Mount Graham red squirrels grows with help from Arizona organizations
For over 25 years, the endangered Mount Graham red squirrel has been quietly battling population decline atop one of Arizona’s tallest mountains.
Endemic to the Pinaleño Mountains in southern Arizona, this species of squirrel was classified as endangered in 1987, with population numbers ranging from 35 to 550.
Habitat loss, wildfires and food competition have contributed to the dwindling population of Mount Graham red squirrels. Efforts from the Arizona Game and Fish Department, the University of Arizona, the Phoenix Zoo and the U.S. Forest Service, populations have almost doubled in the past year from 144 squirrels to an estimated 233 by end of last year.
“It was fantastic,” said Holly Hicks, a Game and Fish small mammal project coordinator. “We all just felt such relief to know that the population can recover after such a devastating wildfire.”
Mount Graham red squirrel numbers over 200 had not been seen since 2017, when the Frye Fire destroyed much of their habitat. The Frye Fire left approximately 35 squirrels total in the Pinaleños – near extinction.
The Phoenix Zoo started a captive breeding program in 2014 to try to breed a healthy population off-site, in case a fire were to strike Mount Graham again. They house four red squirrels, two male and two female, that have yet to produce offspring.
“We have this vision with our partners of being able to create another population that hopefully can serve as an additional backup on the mountain,” said Tara Harris, Phoenix Zoo director of conservation and science. “The risk of wildfire continues to be quite high for these squirrels, and so having that extra population would be really important for making sure that this squirrel continues to exist here in Arizona and in the world.”
