The nation has taken a successful step in tracking the migration route of the gray-faced buzzard eagle, or Butastur indicus, paving the way for better conservation measures for the rare migratory bird, a Forestry Bureau official said.
Conservation Division Director Kuan Li-hao (管立豪) said scientists put satellite transmitters on three gray-faced buzzard eagles as they passed through Taiwan this fall. After being released on Oct. 12 in Kenting (墾丁), the birds reached the Philippines the next day.
Kuan said it was the first time that the migratory movements of the species had been recorded anywhere in the world.

Two of the three birds, nicknamed Cape No. 2 and Cape No. 3, are on Luzon Island, while Cape No. 1 headed further south in the Philippines, Kuan said.
The satellite transmitters on the birds send signals to the research group, which will continue to record the birds’ movements next spring during their migration northward.
Because of budget limitations, the research group could only implant transmitters on three birds.
“But thanks to the research, Taiwan may have the opportunity to cooperate with countries in Southeast Asia, such as the Philippines, to enhance conservation” of this rare species, Kuan said.
The buzzard eagle is listed as protected in the Convention on International Trade in Endangered Species of Wildlife Fauna and Flora.
Normally, 15,000 to 35,000 of the birds pass over Taiwan every year in the spring and autumn, the Forestry Bureau said. This year, however, an estimated 42,000 gray-faced buzzard eagles had crossed over Taiwan by the end of last month — the highest number since the bureau began counting the migration in 1989.
Kuan attributed the higher numbers on the weather, which was relatively stable between Oct. 8 and Oct. 20 compared with previous years.
He said forest district offices had also worked to prevent hunters from killing the birds.
UNDER WATCH: Taiwan will have to establish a standardized nucleic acid testing method to identify the virus and monitor its spread, the CDC said The Langya henipavirus, which can be transmitted from animals to humans, has been discovered in China, with 35 human infections reported so far, Taiwan’s Centers for Disease Control (CDC) said, adding that the nation would establish a nucleic acid testing method to identify the virus. A study titled “A Zoonotic Henipavirus in Febrile Patients in China” that was published in the New England Journal of Medicine on Thursday said that a new henipavirus associated with a fever-causing human illness was identified in China. The study said an investigation identified 35 patients with acute infection of the Langya henipavirus in China’s Shandong
MISSILE PATHS: Certain information on the Chinese missile fire was not disclosed to maintain secrecy over military intelligence-gathering capabilities, the MND said Military experts yesterday speculated on the implication of the government’s tight-lipped response and the lack of air-raid sirens during the first day of China’s military drills the previous day. On Thursday, the Chinese People’s Liberation Army (PLA) launched 11 Dongfeng-series ballistic missiles into waters north, east and south of Taiwan, a day after US House of Representative Speaker Nancy Pelosi’s departure from the country, the Ministry of National Defense (MND) said. The Japanese Ministry of Defense said that China fired nine missiles toward Taiwan, including four that flew over Taiwan proper. However, China’s exhibition of force failed to terrorize the local populace, because
If any war were to break out between the US and China, one trigger might be the increasingly frequent fighter jet encounters near Taiwan. Almost every day, Taiwanese fighter pilots hop in their US-made F-16s to intercept Chinese warplanes screaming past their territory. The encounters probe the nation’s defenses and force the pilots on both sides to avoid mistakes that could lead to a crisis that spins out of control. “I didn’t know whether they would fire at me,” said retired colonel Mountain Wang, recounting a tense five-minute confrontation he had with Chinese People’s Liberation Army (PLA) jets more than a decade
INCREASINGLY EMBOLDENED: China can no longer be dismissed as inexperienced, demonstrating an ability to coordinate land and sea missile systems, an expert said Beijing’s largest-ever exercises around Taiwan have offered essential clues into its plans for a grueling blockade in the event of an attack on Taiwan, and revealed an increasingly emboldened Chinese military, experts said. The visit to Taiwan by US House of Representatives Speaker Nancy Pelosi — second in line to the presidency — sparked outrage from Beijing, which launched vast military maneuvers around the nation, even at the risk of partially exposing its plans to the US and its Asian allies. Mobilizing fighter planes, helicopters and warships, the drills aim to simulate a blockade of Taiwan and include practicing an “attack on
