Search for rare Fiji petrel yields no sightings

A ten-day scientific mission off the coast of Gau Island in Fiji failed to produce any confirmed sightings of the critically endangered Fiji petrel, according to research published in Bird Conservation International. The elusive seabird is considered one of the rarest avian species globally, with estimates indicating that fewer than 50 individuals remain alive.

The expedition was organized by National Geographic Pristine Seas alongside BirdLife International and NatureFiji-MareqetiViti in May 2025. Researchers combed the surrounding waters for upwards of twelve hours each day. During daylight hours, the crew dispersed bait and fish oil across the ocean surface to lure the birds. At night, they projected vertical spotlight beams into the sky and broadcast recorded calls on repeat.

Melania Bulimaitoga, a biologist with BirdLife International, noted that verified human encounters with the species remain exceptionally sparse, with merely 16 recorded observations on land and 22 at sea dating back to 1855. Because so few encounters exist, fundamental details regarding the bird's breeding locations, foraging behavior, and population numbers remain almost entirely unknown. Scientists had hoped to attach a satellite transmitter to a petrel to locate its nests, which have never been identified by researchers.

Community conservation efforts

Despite the absence of sightings, the project helped document the sole known audio recording of the petrel. Furthermore, Gau Island residents affirmed their dedication to shielding mountain forest canopies where the birds are suspected to breed. Endemic to Fiji and featured on the nation's 20-dollar banknote, the petrel holds cultural importance on Gau, inspiring traditional lullabies and oral histories passed down through generations.

Village leaders described ancestral recollections of gathering seabird eggs on forested slopes behind their communities, illustrating that the birds were once far more common. Today, however, any surviving petrels face severe pressure on their only known island from habitat degradation and introduced predators, including feral cats, rats, and pigs.

Expedition leader Lindsay Young of Pristine Seas explained that while the lack of sightings was disappointing, a single survey provides only a brief snapshot. Researchers noted that adverse weather, including a nearby cyclone and an intense El Niño, may have influenced petrel activity during the search. Conservationists emphasize that local initiatives to control invasive species and protect upland forests offer the best hope for the bird's survival.
