On the Trail Illegal Hunters That Illegally Capture the Nation's Rare Songbirds.
The activist's eyes scan across vast expanses of open meadows, searching for any movement in the inky blackness.
He utters a hushed tone as they attempt to locate a place of cover in the open area. In the distance, the huge urban center of Beijing has yet to wake. As we wait, the only sound is our own breath.
And then, as the sky begins to brighten with the approaching day, the sound of footsteps emerges. The hunters have arrived.
Caught
Across the heavens, a multitude of winged travelers, many so small that they can fit in the cup of a hand, are traveling to the south for winter.
They have taken advantage of the warmer months in northern regions, feasting on bugs and berries. As the year comes to a close and cold breezes bring the initial freeze of winter, they are flying to warmer places to breed and eat.
China is home to 1500-plus bird species, accounting for thirteen percent of the world's total – over eight hundred of those are migratory birds. Four of the nine major flyways they follow cross through China.
This particular field in question, on the fringes of the Chinese capital, is an haven for small birds – farther in and the city skies offer little opportunity to rest among towering rows of concrete.
It is equally attractive for the poachers and their "barely visible nets", so thin you can hardly spot them.
The one we nearly walked into was extending over half the length of the field and propped up with wooden sticks. In the middle, a tiny bird was desperately trying to untangle itself, but the more it struggled, the more its feet got ensnared.
This was a meadow pipit, a protected bird in China, and an important "indicator species" – that means if its numbers are thriving, so is its environment.
Hunting the Hunters
This activist, does this work for free using his own savings. He has forgone many nights of sleep to rescue birds, and he has spent the last 10 years convincing the police in Beijing to prioritize this issue.
"Initially, authorities were indifferent," he remarks.
So he recruited volunteers who did care and formed a group known as the Beijing Migratory Bird Squad. He organized public meetings and invited the leaders of the relevant authorities. These consistent and determined acts of advocacy seem to have paid off. The police found that catching poachers also helped in identifying other kinds of illegal operations.
"We found our goals were somewhat shared," Silva says, noting that enforcement is still patchy.
His passion for avian life started in childhood. He was raised in the 1990s in a very different Beijing.
He recalls wandering in the fields on the city's edges where he discovered birds, frogs and snakes. "But starting from the 2000s, the transformation was dramatic."
Industrialization brought millions of rural workers to cities. This fast-paced development meant grasslands were considered land for construction, not sanctuaries to conserve.
The transformation was alarming. The grasslands receded, as did the wildlife they housed.
"I made the choice back then to pursue environmental protection and I followed this course," he says.
This has not made for an simple journey. One of Beijing's biggest bird dealers discovered he was being investigated by Silva and fought back.
"He assembled several of his associates who surrounded me and assaulted me," Silva remembers. He says he went to the police but the perpetrators were not held accountable.
He has also lost his team of helpers over the years. This work requires patience and night vigils. Silva says not many are prepared for the challenging and occasionally risky job.
"This is my full-time commitment," he says. "I treat it as a mission because if you want to solve this big problem, you must give it your all. You can't do it part-time."
He says donations covers some of the costs – more than 100,000 yuan a year – but donations have dipped because of the economic situation.
So he has adopted new ways to hunt the hunters.
He analyzes aerial photos to find the paths worn away by the poachers. He charts these against the birds' flight paths and looks for areas where they may rest. The satellite images can even show lines of net traps which can capture scores of small birds during darkness.
"Siberian rubythroats and bluethroats sell for a high price," Silva says. "In urban centers like Beijing and Tianjin, those who want to own songbirds are now often affluent."
While there are environmental regulations in place, Silva reckons the fines to punish the crime do not exceed the potential profits of trapping and trading songbirds.
Keeping a caged bird was – and for some people in China, still is – a status symbol. This dates back to the imperial era. Wealthy individuals would build ornate bamboo cages to display their birds.
This custom that persists mainly among older individuals in their later years. Silva says older Chinese people don't realise they are committing a wildlife crime, or understand that so many more birds had to die in a trap for them to purchase a caged bird.
"This generation often lacked enough to eat in their youth. Now with a little money, they have adopted the practice of caging birds," he says. "The nation progressed so fast, there was no time to raise awareness about ecology. Once people's attitudes are formed, they're really hard to change."
Disrupted
On a long low wall in Beijing, a vendor has several tiny enclosures with tiny twittering birds.
Another man is positioned near a local market holding a bird cage shrouded in a dark cloth. He informs passers-by discreetly that his songbird is rare, worth about 1900 yuan.
This offers a view of an traditional side of the city where informal vendors have established a niche trade.
The area alongside the water extends over several miles and on a sunny weekday morning, there were shoppers browsing everything from old trinkets to dentures.
We were told that protected birds could be bought 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 two or three in their hands. Most were concealed by dark cloth.
But today there would be no sales because the police had arrived. They were interviewing the bird owners and taking names. Unyielding, one man said he was {taking his caged bird for a walk|simply exercising his
