On the Trail Poachers Who Illegally Snare the Nation's Rare Wild Birds.
The conservationist's gaze sweeps over miles of open meadows, searching for suspicious activity in the early morning gloom.
He speaks in a muted voice as they attempt to locate a concealed position in the open area. In the distance, the huge urban center of Beijing has yet to wake. As we wait, the only sound is the quiet of the morning.
Suddenly, as the sky turns a shade lighter before dawn, there is the crunch of footsteps. The poachers are here.
Snared
Across the heavens, countless migratory birds, many so small that they can fit in the palm of your hand, are migrating south for winter.
They have taken advantage of the long summer days in northern regions, eating insects and fruit. As the year winds down and icy winds bring the initial freeze of winter, they head to warmer places to find food and shelter.
China is home to over 1500 bird species, which is about thirteen percent of the global population – more than 800 of those are migratory birds. Four of the nine major migration routes they follow cross through China.
The area of meadow being monitored, on the edges of the Chinese capital, is an refuge for small birds – any further and the city skies offer little opportunity to rest among clusters of concrete.
It is equally attractive for the poachers and their "barely visible nets", so fine you can almost miss them.
The one we nearly walked into was extending over half the length of the field and propped up with bamboo poles. At its center, a small finch was struggling frantically to untangle itself, but the more it moved, the more its claws became tangled.
This was a protected songbird, a protected bird in China, and an important "indicator species" – which signifies if its population is healthy, so is its ecosystem.
Tracking the Trappers
The conservationist, in his thirties, carries out this mission for free using his own savings. He has given up on many sleeping hours to release trapped birds, and he has spent the last decade persuading the police in Beijing to enforce the law.
"Initially, authorities were indifferent," he states.
So he enlisted helpers who were concerned and established a group known as the Bird Protection Unit. He organized public meetings and invited the leaders of the relevant authorities. These consistent and determined acts of persuasion have shown results. The police found that catching poachers also led to uncovering other kinds of illegal operations.
"It became clear our goals were somewhat shared," Silva says, while pointing out that the response is not uniform.
His passion for avian life started in childhood. He was raised in the nineties in a very different Beijing.
He remembers wandering in the fields on the city's edges where he encountered birds, frogs and snakes. "But starting from the 2000s, the transformation was dramatic."
Industrialization brought millions of rural workers to cities. This expansion meant grasslands were considered land for construction, not conservation areas to conserve.
This shift shocked him. The grasslands began to shrink, as did the habitats they supported.
"I made the choice back then to work in conservation and I chose this direction," he says.
This has not made for an simple journey. A major Beijing's biggest bird dealers discovered he was under scrutiny by Silva and fought back.
"He gathered several of his accomplices who surrounded me and assaulted me," Silva recalls. He says he went to the police but those responsible were not brought to justice.
He has also lost his army of volunteers over the years. This work requires stealth and sleepless nights. Silva says few people are prepared for the challenging and occasionally risky job.
"My life is devoted to this," he says. "I made it a project because if you want to tackle this challenge, you must devote yourself wholeheartedly. You can't do it part-time."
He says fundraising pays for some of the costs – over 100,000 yuan annually – but funding has declined because of the slowing economy.
So he has developed new ways to hunt the hunters.
He analyzes satellite imagery to find the routes created by the poachers. He charts these against the birds' migratory routes and looks for areas where they may stop for the night. The aerial views can even show netting setups which can catch hundreds of small birds during darkness.
"Certain prized species command a high price," Silva says. "In big cities like Beijing and Tianjin, those who want to keep birds 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.
Owning a pet bird was – and for some generations in China, still is – a status symbol. This originates from the imperial era. Wealthy individuals would build ornate bamboo cages for their birds.
It's a tradition that continues mainly among retired men in their later years. Silva says older Chinese people may not understand they are breaking the law, or understand that so many more birds had to die in a trap so they could buy a caged bird.
"This generation often lacked enough to eat in their youth. Now with a little money, they have inherited the habit and custom of keeping birds in cages," he says. "China developed so fast, there was no time to raise awareness about ecology. Once adults' values are set, they're extremely difficult to change."
Disrupted
On a long low wall in Beijing, a vendor has several small cages with chirping songbirds.
Another man is positioned near a local market holding a bird cage covered by a black veil. He tells passers-by quietly that his songbird is valuable, worth about 1900 yuan.
This is a glimpse of an traditional side of the city where small unofficial traders have established a niche trade.
The area alongside the water extends over several miles and on a typical day, there were people looking at everything from vintage jewellery to false teeth.
We were told that wild songbirds could be bought in a nearby green space. It was easy to find.
Loud music played from a speaker under the low trees where a group of elderly ladies were performing a fan dance. Nearby several men, all in their later years, had gathered with bird cages – some had multiple in their hands. Most were covered in dark cloth.
But today there would be no transactions 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
