Tracking Illegal Hunters Illegally Trapping the Nation's Endangered Wild Birds.
Silva Gu's vision darts over miles of dense fields, looking for signs of life in the pre-dawn darkness.
He speaks in a hushed tone as we try to find a place of cover in the open area. Behind us, the vast metropolis of Beijing slumbers on. As we wait, the only sound is the sound of breathing.
And then, as the sky begins to brighten with the approaching day, the sound of footsteps emerges. The hunters have arrived.
Snared
In the skies above us, a multitude of winged travelers, some tiny enough that they could rest in the palm of your hand, are journeying southward for winter.
They have utilized the warmer months in northern regions, consuming insects and fruit. As the year winds down and cold breezes bring the first frosts of winter, they are flying to warmer places to breed and eat.
The nation hosts over 1500 bird species, which is about 13% of the global population – more than 800 of those are birds that migrate. Four of the nine major flyways they follow cross through China.
This particular field in question, on the edges of the Chinese capital, is an haven for small birds – farther in and the city skies offer little opportunity to rest among forests of concrete.
It is equally attractive for the poachers and their "fine nets", so fine you can hardly spot them.
The trap we stumbled upon was strung across half the length of the field and propped up with bamboo poles. At its center, a tiny bird was struggling frantically to escape, but the more it moved, the more its claws became tangled.
This was a meadow pipit, a species under protection in China, and an important "indicator species" – that means if its numbers are thriving, so is its ecosystem.
Hunting the Hunters
This activist, performs this duty for free using his own savings. He has forgone many sleeping hours to release trapped birds, and he has spent the last decade urging the police in Beijing to take this crime seriously.
"Initially, authorities were indifferent," he states.
So he enlisted helpers who were concerned and launched a group called the Bird Protection Unit. He organized community gatherings and brought in the heads of the relevant authorities. These small and persistent acts of advocacy have shown results. The police discovered that catching poachers also led to uncovering other kinds of criminal activity.
"We found our goals were somewhat shared," Silva says, adding the caveat that enforcement is still patchy.
His passion for avian life began during childhood. He grew up in the 1990s in a much changed capital.
He recalls roaming through the grasslands 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 rapid urbanisation meant grasslands were viewed as areas for development, not sanctuaries to conserve.
The transformation was alarming. The grasslands began to shrink, as did the ecosystems they sustained.
"I decided back then to dedicate myself to preservation and I took this path," he says.
This has not made for an simple journey. A major Beijing's biggest bird dealers found out he was under scrutiny by Silva and fought back.
"He assembled several of his accomplices who confronted me and beat me up," Silva remembers. He says he went to the police but the perpetrators were not brought to justice.
He has also lost his team of helpers over the years. This work demands patience and night vigils. Silva says not many are willing to take on the challenging and occasionally risky job.
"My life is devoted to this," he says. "I made it a project because if you want to address this major issue, you must devote yourself wholeheartedly. You cannot be half-hearted."
He says fundraising pays for some of the costs – more than 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 satellite imagery to find the paths created by the poachers. He maps those against the birds' migratory routes and looks for areas where they may stop for the night. The aerial views can even show lines of net traps which can catch hundreds of small birds during darkness.
"Siberian rubythroats and bluethroats sell for a premium," Silva says. "In big cities like Beijing and Tianjin, those who want to own songbirds are now quite wealthy."
Although there are wildlife laws in place, Silva reckons the penalties to punish the crime do not exceed the potential profits of catching and selling songbirds.
Owning a pet bird was – and for some generations in China, still is – a status symbol. This dates back to the imperial era. Nobles and elites would build elaborate bamboo cages to display their birds.
It's a tradition that persists mainly among retired men in their later years. Silva says some elderly citizens don't realise they are breaking the law, or understand that so many more birds were killed in a trap so they could buy a pet.
"These individuals didn't even have enough to eat growing up. Now with some disposable income, they have inherited the practice of caging birds," he says. "The nation progressed so fast, there was little opportunity to educate people about ecology. Once people's attitudes are formed, they're really hard to change."
Busted
On a long low wall in Beijing, a vendor has several tiny enclosures with tiny twittering birds.
A separate individual is positioned near a nearby market holding a bird cage shrouded in a dark cloth. He informs passers-by quietly that his songbird is valuable, worth nearly 1900 yuan.
This offers a view of an traditional side of the city where informal vendors have created their own market.
The area alongside the water stretches for several miles and on a typical day, there were shoppers browsing everything from old trinkets to false teeth.
We were told that wild songbirds could be purchased in a nearby green space. The location was not concealed.
Loud music played from a speaker under the low trees where a troop of elderly ladies were choreographing a traditional dance. Close by several men, all in their later years, had congregated with bird cages – some had two or three in their hands. Most were concealed by dark cloth.
But on this occasion there would be no sales because the police had appeared. They were interviewing the bird owners and recording details. Unyielding, one man claimed he was {taking his caged bird for a walk|simply exercising his
