Egrets adapt better than most birds when a solar farm moves into their habitat, experts said, after images of egrets excreting feces on solar panels went viral online.
On Tuesday, the Budai Salt Pan Wetlands (布袋五鹽田) posted images on Facebook of birds resting on solar panels erected in a detention basin, while close-ups showed that the panels had been covered with the egrets’ droppings.
The basin in Chiayi County’s Budai Township (布袋) was in 2019 transformed from an abandoned salt pan into a solar farm, the Facebook page said in Chinese and English.

While the solar farm became new terrain for the egrets, other species, such as tufted ducks, greater scaups and Baer’s pochards, have lost their main habitat, as the ducks need open water in which to rest and search for food, it added.
Meanwhile, the panels’ ability to generate power is expected to decline due to the egrets’ droppings and energy developers must have the panels washed more often, it said, suggesting the venue might not be ideal for photovoltaic installations.
The Facebook post attracted many comments, with some users saying that the photographs show “nature’s revenge” and bemoaning the further environmental damage caused by cleaning chemicals.
Energy developer New Green Power Co welcomed the birds, saying that the photographs prove that the panels do not affect their habitat too much.
The panels function normally, but they do require monthly cleaning when birds are migrating, the company said on Thursday.
The solar farm, which started generating electricity in September last year, is the nation’s largest photovoltaic installation erected in a detention basin, the company said in a news release in November.
It has an installed capacity of 35.5 megawatts and can generate more than 50 million kilowatt-hours of electricity per year, the firm said.
The panels do not cover more than half of the basin’s water area of 74 hectares, and the solar farm demonstrates that ecology and industrial development can cohabitate, it said.
Taiwan Wild Bird Federation secretary-general Allen Lyu (呂翊維) said that Budai has been a hotspot for various bird species and that some species, such as egrets, more easily adapt to changes in their environment.
However, the habitats of other species, such as the tufted ducks, are limited due to their poor adaptability, he said, adding that the solar panels have affected their most important habitat in the region.
Not all power installations have negative effects, as some solar panels, if planned well, can serve as “ecological islands” for birds, Lyu added.
Careful environmental assessments are needed before projects are implemented if energy installations are to coexist with nature and have minimal effect; otherwise, energy developers end up paying greater unexpected costs, he said.
Asked about the number of tufted ducks on the solar farm, the Council of Agriculture’s Endemic Species Research Institute said that it has been monitoring the ducks’ migration to Budai since 2016.
The area had more than 800 tufted ducks in 2016, and 1,500 to 1,600 by 2019, research institute data showed.
However, after the solar farm’s construction, their number dwindled to 500 to 600, data released this month by the institute showed.
The ducks’ main habitat in the basin, especially the southern part, is covered with large panels, the institute said, adding that the remaining open water is largely reduced and fragmented.
The ducks did not move to the basin’s northern part, where there is more open water, it said.
They likely migrated elsewhere, it added.
The manufacture of the remaining 28 M1A2T Abrams tanks Taiwan purchased from the US has recently been completed, and they are expected to be delivered within the next one to two months, a source said yesterday. The Ministry of National Defense is arranging cargo ships to transport the tanks to Taiwan as soon as possible, said the source, who is familiar with the matter. The estimated arrival time ranges from late this month to early next month, the source said. The 28 Abrams tanks make up the third and final batch of a total of 108 tanks, valued at about NT$40.5 billion
Two Taiwanese prosecutors were questioned by Chinese security personnel at their hotel during a trip to China’s Henan Province this month, the Mainland Affairs Council (MAC) said yesterday. The officers had personal information on the prosecutors, including “when they were assigned to their posts, their work locations and job titles,” MAC Deputy Minister and spokesman Liang Wen-chieh (梁文傑) said. On top of asking about their agencies and positions, the officers also questioned the prosecutors about the Cross-Strait Joint Crime-Fighting and Judicial Mutual Assistance Agreement, a pact that serves as the framework for Taiwan-China cooperation on combating crime and providing judicial assistance, Liang
A group from the Taiwanese Designers in Australia association yesterday represented Taiwan at the Midsumma Pride March in Melbourne. The march, held in the St. Kilda suburb, is the city’s largest LGBTQIA+ parade and the flagship event of the annual Midsumma Festival. It attracted more than 45,000 spectators who supported the 400 groups and 10,000 marchers that participated this year, the association said. Taiwanese Designers said they organized a team to march for Taiwan this year, joining politicians, government agencies, professionals and community organizations in showing support for LGBTQIA+ people and diverse communities. As the first country in Asia to legalize same-sex
MOTIVES QUESTIONED The PLA considers Xi’s policies toward Taiwan to be driven by personal considerations rather than military assessment, the Epoch Times reports Chinese President Xi Jinping’s (習近平) latest purge of the Chinese People’s Liberation Army (PLA) leadership might have been prompted by the military’s opposition to plans of invading Taiwan, the Epoch Times said. The Chinese military opposes waging war against Taiwan by a large consensus, putting it at odds with Xi’s vision, the Falun Gong-affiliated daily said in a report on Thursday, citing anonymous sources with insight into the PLA’s inner workings. The opposition is not the opinion of a few generals, but a widely shared view among the PLA cadre, the Epoch Times cited them as saying. “Chinese forces know full well that
