BEIJING (XINHUA) - A private home in an old hutong, or alleyway, in downtown Beijing has welcomed a group of rare guests - five fledgling swallows.
"I haven't seen a swallows' nest for over 30 years," said Madam Fan Liandi, a retired Chinese language teacher. She lives at Dazhiqiao Hutong, just south of Xuanwumen in downtown Beijing.
"Last year, I had the house gate repainted, and in spring, swallows started building a nest under the roof," Madam Fan said.
Many years ago, swallows were a common sight in Beijing, said Dr Gao Wu, an ornithologist and professor at Capital Normal University. "When the population rose quickly, birds started to leave because they couldn't build nests on modern apartment buildings," said Dr Gao.
"The fact that they are coming back is a good phenomenon, it means the area is quiet enough, and there are abundant food resources," he said.
Dazhiqiao Hutong is 186m long. Before the Qing Dynasty (1644-1911), it was a drainage ditch. Teahouses and restaurants started to be built in late Qing dynasty and it eventually became one of the most crowded and chaotic alleyways in southern part of downtown Beijing.
Since April last year, illegally-constructed structures and hole-in-the-wall restaurants have been dismantled. Wires that used to criss-cross above the buildings were buried underground. Roads were expanded, and dilapidated houses repaired. Dazhiqiao is one of seven alleyways that have been renovated south of Xuanwumen.
"The environment is much quieter now, and I guess that's why the birds are coming back," said Madam Fan.
Beijing's efforts to dismantle illegal constructions, build parks and wetlands, and restore ancient alleyways have helped clean up the city environment.
According to municipal statistics, Beijing has built 210 large parks around the city. Its green-zone coverage is about 26.8 per cent, up about 12 percentage points compared to the figure five years ago.
Beijing currently has 50,000 hectares of wetlands. By 2020, it plans to add another 3,000 hectares. The green-zone coverage will be at least 30 per cent by then, according to the government plan.
Beijing Wildlife Rescue and Rehabilitation Centre, which monitors the wild bird population, said that from 2014 to 2015, there were about 150 species of birds in Beijing, and the number has risen to 200 since last year (2016).
"These swallows will grow and one day they will leave my house, but I hope more birds will come and build nests here, like they did when I was young," said Madam Fan.
