The Bahama Nuthatch, Thought to Be Lost to Hurricanes, Is Not Extinct鈥擸et

Researchers sighted a few of the critically endangered birds on a three-month, 430-mile expedition to Grand Bahama's pine forests this spring.

After hundreds of miles and three months of searching through dense forests of Caribbean pine and poisonwood,听two separate research teams听delivered on what seemed like a near-impossible task: They found the missing Bahama听Nuthatch.听

Confined to Grand Bahama, the tiny bird鈥攐fficially a subspecies of the Brown-headed Nuthatch, though some ornithologists recognize it as a full species鈥攚as largely thought to be extinct after Hurricane Matthew ravaged the island in 2016, according to . The Bahama Nuthatch has declined听since the 1950s from a combination of habitat loss,听invasive species, and听tourist developments; its population was optimistically estimated at 1,800 individuals in 2004.听

Then听it got worse: The population plummeted after a series of hurricanes struck the island, sending salty storm surges inland which killed the pine trees the nuthatches require for nesting. Only 23 individuals were spotted in 2007. The widespread destruction caused by听Hurricane Matthew听and its 120-mile-per-hour gusts, some thought, had to be the last straw. No birds had been sighted since June 2016.

But a few biologists held out hope. This spring, , graduate students based at England's University of East Anglia, set out on a three-month expedition, in partnership with听the Bahamas National Trust and BirdLife International,听to find the nuthatch and other bird species endemic to Grand Bahama.听They scoured the island, hiking听some听430 miles听while playing bird calls to attract the bird during its breeding season. A separate team of Bahamian students, led by of University of The Bahamas-North, also searched for the bird using different methods, the press release says.听

It wasn't easy. Six weeks and 250 miles in, Gardner and Pereira had almost given up hope that they'd ever find the elusive birds.They were exhausted after听searching听464 survey points throughout the vast, undeveloped听pine forest and coming up empty. Then,听Gardner heard the bird鈥檚 unmistakable听high-pitched call and saw it flying down from the treetops toward him.

鈥淚 shouted with joy, I was ecstatic!鈥澨鼼ardner said in the press release.听

Gardner and Pereira听made six nuthatch sightings total over the course of three months, but never saw multiple nuthatches together,听leading them to believe that there might听only be one remaining. McKenzie鈥檚 team reported five separate sightings,听including one where they reported a pair of nuthatches together.听

, a conservation biologist at the University of East Anglia who supervised the school's search听team, said in a press release that she doesn鈥檛 believe the Bahama听Nuthatch can make a comeback;听its numbers are too low and the causes of its decline still unclear. However, she鈥檚 optimistic that there's still time to help other birds endemic to Grand Bahama's pine forest, she said.听

鈥淚t is still absolutely crucial that conservation efforts in the native Caribbean pine forest do not lapse, as it is such an important habitat for other endemic birds including the Bahama Swallow, Bahama Warbler, and Bahama Yellowthroat,鈥 Bell said in the press release. She also noted the habitat's importance to neotropical migrants that breed in North America, such as the Kirtland's Warbler.

When Gardner and Pereira spotted the lone nuthatch, the听, completely unaware of the elation its presence had caused. Though the future of this Bahama Nuthatch is still bleak, it's somehow comforting听to know听that听at least one bird managed to ride听out the storm.听
