On the Trail Illegal Hunters Who Illegally Snare the Nation's Rare Songbirds.
The activist's gaze sweeps across miles of open meadows, searching for suspicious activity in the inky blackness.
He utters a hushed tone as the team seeks a concealed position in the fields. In the distance, the huge urban center of Beijing has yet to wake. As we wait, the only sound is our own breath.
Suddenly, as the sky starts to lighten with the approaching day, there is the crunch of footsteps. Illegal trappers are present.
Trapped
Overhead, billions of birds, some tiny enough that they could rest in the cup of a hand, are journeying southward for winter.
They have benefited from the warmer months in Siberia, or Mongolia, eating insects and fruit. As the year nears its end and cold breezes bring the early cold of winter, they head to more temperate climates to nest and feed.
There are over 1500 bird species, representing roughly thirteen percent of the planet's species – over eight hundred of those are birds that migrate. Several of the major paths they follow cross through China.
This particular field in question, on the edges of the Chinese capital, is an oasis for small birds – farther in and the city skies offer scant chance to rest among forests of concrete.
It is equally attractive for the poachers and their "fine nets", so delicate you can almost miss them.
A net we almost encountered was extending over half the length of the field and held up with bamboo poles. At its center, a small finch was fighting hard to escape, but the more it moved, the more its feet got ensnared.
This was a protected songbird, a species under protection in China, and an important "indicator species" – which signifies if its numbers are thriving, so is its environment.
Tracking the Trappers
Silva, who is in his 30s, carries out this mission for free using his own savings. He has sacrificed many nights of sleep to set songbirds free, and he has spent the last decade persuading the police in Beijing to take this crime seriously.
"Back in 2015, authorities were indifferent," he states.
So he recruited volunteers who did care and formed a group known as the Beijing Migratory Bird Squad. He organized community gatherings and brought in the leaders of the relevant authorities. These small and persistent acts of advocacy appear to have worked. The police realized that catching poachers also led to tracking down other kinds of illegal operations.
"We found our goals were partially aligned," Silva says, adding the caveat that the response is not uniform.
Silva's love of birds began during childhood. He was raised in the 1990s in a much changed capital.
He recalls exploring the grasslands on the city's edges where he discovered birds, frogs and snakes. "However, beginning in the 2000s, the transformation was dramatic."
Rapid economic growth brought millions of rural workers to cities. This expansion meant grasslands were seen as empty places to build, not sanctuaries to preserve.
The change stunned Silva. The grasslands started disappearing, as did the wildlife they housed.
"I decided back then to pursue environmental protection and I chose this direction," he says.
This has not made for an simple journey. One of Beijing's biggest bird dealers found out he was being investigated by Silva and fought back.
"He gathered several of his accomplices who confronted me and assaulted me," Silva recalls. He says he reported to the police but those responsible were not held accountable.
He has also lost his team of helpers over the years. This work requires patience and night vigils. Silva says few people are prepared for the difficult – and sometimes dangerous job.
"I do this full-time," he says. "I made it a project because if you want to address this major issue, you must commit completely. You can't do it part-time."
He says fundraising pays for some of the costs – over 100,000 yuan a year – but funding has declined because of the economic situation.
So he has adopted new ways to hunt the hunters.
He studies aerial photos to find the routes created by the poachers. He charts these against the birds' flight paths and looks for areas where they may stop for the night. The aerial views can even show lines of net traps which can capture hundreds of small birds during darkness.
"Certain prized species command a premium," Silva says. "In urban centers like Beijing and Tianjin, those who want to own songbirds are now often affluent."
Although there are wildlife laws in place, Silva believes the penalties to punish the crime do not exceed the potential profits of catching and selling songbirds.
Keeping a caged bird was – and for some people in China, still is – a mark of prestige. This originates from the imperial era. Nobles and elites would build ornate bamboo cages to display their birds.
It's a tradition that continues mainly among older individuals in their later years. Silva says older Chinese people may not understand they are committing a wildlife crime, or understand that so many more birds had to die in a trap so they could buy a caged bird.
"This generation didn't even have enough to eat growing up. Now with a little money, they have adopted the practice of caging birds," he says. "China developed so fast, there was little opportunity to raise awareness about the environment. Once adults' values are formed, they're extremely difficult to change."
Apprehended
Along a riverside path in Beijing, a trader has several tiny enclosures with chirping songbirds.
Another man is positioned near a nearby market holding a bird cage covered by a dark cloth. He informs passers-by quietly that his songbird is valuable, worth nearly 1900 yuan.
This is a glimpse of an old Beijing where informal vendors have created their own market.
The path by the river extends over several miles and on a typical day, there were shoppers browsing everything from vintage jewellery to dentures.
Information suggested that wild songbirds could be purchased in a nearby green space. The location was not concealed.
Music was blasting from a speaker in a shaded area where a troop of elderly ladies were performing a fan dance. Nearby several men, all over 50, had congregated with bird cages – some had multiple in their hands. Most were concealed by black fabric.
But today there would be no sales because the police had arrived. They were questioning the bird owners and recording details. Unyielding, one man claimed he was {taking his caged bird for a walk|simply exercising his
