Critically Endangered Megabat Believed Dead Less Than a Month After Release in Hualien

Critically Endangered Megabat Believed Dead Less Than a Month After Release in Hualien

Taipei, Taiwan – A critically endangered megabat species native to Taiwan, known as the Pteropus dasymallus formosus, is believed to have been killed by a predator less than a month after being released back into the wild. The discovery was made by the Hualien branch of the Forestry and Nature Conservation Agency (FNCA), which confirmed the death of the bat, named Fubao (蝠寶), on Tuesday.

Fubao, who had been rehabilitated after being found injured in April, was tracked for two weeks after its release on November 12. The bat’s remains were discovered near its roost, along with a GPS tracker that had been used to monitor its movements. Experts speculate that the bat was likely killed by a day-active predator, possibly a raptor, before December 5.

Rehabilitation Efforts and Tragic Outcome

Fubao’s Recovery and Release into the Wild
Fubao was found by a citizen in Hualien City in April when it was just a two-week-old, injured bat weighing only 80 grams. After being rescued and taken to the Hualien Forestry Agency, it was nursed back to health and reached a healthy weight of 307 grams as an adult bat.

On November 12, after being deemed fit for release, Fubao was returned to the wild in the mountainous areas of Hualien, with experts closely monitoring its recovery. The research team took extra care in selecting a roost with low brush cover to give the bat the best chance of survival.

However, a tracking system was put in place to monitor Fubao’s daily activity and survival. For the first two weeks, the bat’s movements were monitored, with researchers observing the bat remaining in a fixed location between noon on December 5 and the morning of December 6, leading them to conclude that it was likely dead on or before December 5.

Speculation of Predator Attack
Experts from the Forestry and Nature Conservation Agency believe that the bat’s death could have been caused by a day-active raptor, which may have preyed on Fubao. The GPS tracker found near the bat’s remains suggested that the bat had likely been killed by a predator near its roost.

While the loss of such a rare bat is deeply saddening, it also serves as an important learning experience for the agencies involved in rehabilitating and reintroducing wild animals. The tragic end of Fubao highlights the challenges faced by endangered species trying to survive in a world increasingly hostile to wildlife.

Endangered Megabat Species Faces Decline in Population

Critical Status of Pteropus Dasymallus Formosus
The Pteropus dasymallus formosus, also known as the Taiwanese megabat, is one of Taiwan’s most endangered species. Historically, this megabat was abundant on Green Island, which lies 33 km off the coast of Taitung County. In the 1970s, up to 2,000 individuals were reported on the island.

However, due to the loss of its natural habitat, the population of this megabat has declined significantly. The species has since migrated to other parts of Taiwan, including Taitung, Hualien, Kaohsiung, and Yilan. Conservation efforts have been ongoing, with the Taiwan Endemic Species Research Institute and the Bat Association of Taiwan conducting studies and monitoring the population.

In 2005, an investigation found fewer than 10 bats on Green Island, and studies conducted between 2005 and 2009 estimated that only 12 of these bats remained on the island. This rapid population decline has led experts to classify the Pteropus dasymallus formosus as critically endangered, making every individual crucial for species preservation.

Frequently Asked Questions (FAQs)

Q1: What happened to the megabat named Fubao?
A1: Fubao, a critically endangered megabat species, was found dead less than a month after being released into the wild. Experts believe it was likely killed by a predator, possibly a day-active raptor, based on the discovery of its remains and GPS tracker.

Q2: Why is the Pteropus dasymallus formosus species endangered?
A2: The Taiwanese megabat faces a significant decline in population due to habitat loss, with the species migrating from its original home on Green Island to other parts of Taiwan. Conservation efforts have been crucial in trying to preserve this rare species.

Q3: How did researchers track Fubao’s survival after release?
A3: Researchers monitored Fubao’s movements through a GPS tracker placed on the bat. For the first two weeks after its release, Fubao’s daily activity was recorded, but it stopped moving from December 5, which led researchers to conclude that it had died shortly before that date.

Q4: Where can people report sightings of this endangered species?
A4: The Forestry and Nature Conservation Agency encourages the public to report sightings of the Pteropus dasymallus formosus by calling the 1999 hotline or the 0800-057930 number. Illegal capture or transport of the species can result in fines.

Q5: What is the current status of the Taiwanese megabat population?
A5: The population of Pteropus dasymallus formosus has sharply declined over the years. Fewer than 12 bats were reported on Green Island between 2005 and 2009, and the species is now classified as critically endangered.

Conclusion: A Cautionary Tale for Conservation Efforts

The tragic death of Fubao, though heartbreaking, underscores the challenges of wildlife conservation for endangered species. Despite the best efforts of various organizations and agencies to rehabilitate and reintroduce the Taiwanese megabat, natural threats such as predators remain a significant challenge for the survival of this species in the wild. Continued conservation work and vigilance are needed to ensure the survival of the Pteropus dasymallus formosus and other endangered wildlife in Taiwan.
