On the Trail Poachers That Illegally Capture China's Protected Wild Birds.
The activist's eyes scan across miles of dense fields, searching for any movement in the inky blackness.
He speaks in a hushed tone as we try to find a spot to hide in the open area. Behind us, the vast metropolis of Beijing slumbers on. During the vigil, we hear only the sound of breathing.
And then, as the sky starts to lighten ahead of sunrise, we hear footsteps. The poachers are here.
Snared
Overhead, a multitude of winged travelers, many so small that they can fit in the palm of your hand, are journeying southward for winter.
They have taken advantage of the warmer months in Siberia, or Mongolia, consuming insects and fruit. As the year comes to a close and icy winds bring the first frosts of winter, they are flying to southern locales to find food and shelter.
There are more than 1,500 bird species, which is about thirteen percent of the global population – over eight hundred of those are birds that migrate. Several of the major flyways they follow cross through China.
The patch of grassland being monitored, on the fringes of the Chinese capital, is an haven for small birds – any further and the city skies offer little opportunity to rest among towering rows of concrete.
It is equally attractive for the poachers and their "mist nets", so delicate you can barely see them.
The one we nearly walked into was strung across half the length of the field and held up with wooden sticks. At its center, a meadow pipit was desperately trying to free his legs, but the more it struggled, the more its feet got ensnared.
This was a protected songbird, a protected bird in China, and an important "bio-indicator" – which signifies if its population is healthy, so is its ecosystem.
Hunting the Hunters
This activist, performs this duty for free using his personal funds. He has sacrificed many nights of sleep to set songbirds free, and he has spent the last decade urging the police in Beijing to take this crime seriously.
"In the early days, authorities were indifferent," he remarks.
So he recruited volunteers who were concerned and launched a group called the Bird Protection Unit. He held community gatherings and brought in the heads of the relevant authorities. These small and persistent acts of advocacy seem to have paid off. The police found that catching poachers also led to identifying other kinds of illegal operations.
"We found our objectives became somewhat shared," Silva says, adding the caveat that the response is not uniform.
This fascination with birds started in childhood. He was raised in the 1990s in a much changed capital.
He recalls roaming through the fields on the city's edges where he discovered birds, frogs and snakes. "But starting from the 2000s, the transformation was dramatic."
Rapid economic growth brought millions of rural workers to cities. This fast-paced development meant grasslands were seen as areas for development, not protected zones to conserve.
The transformation was alarming. 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 discovered he was being investigated by Silva and fought back.
"He assembled several of his associates who surrounded me and beat me up," Silva recalls. He says he went to the police but those responsible were not held accountable.
He has also seen the departure of his team of helpers over the years. This work requires covert operations and lost sleep. Silva says not many are willing to take on the difficult – and sometimes dangerous job.
"My life is devoted to this," he says. "I made it a project because if you want to solve this big problem, you must give it your all. You can't do it part-time."
He says fundraising 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 track the poachers.
He studies aerial photos to find the paths created by the poachers. He charts these against the birds' migratory routes and looks for areas where they may stop for the night. The satellite images can even show netting setups which can capture scores of small birds at night.
"Certain prized species sell for a high price," Silva says. "In urban centers like Beijing and Tianjin, those who want to keep birds are now quite wealthy."
Although there are wildlife laws in place, Silva argues the fines to punish the crime do not exceed the potential profits of trapping and trading songbirds.
Owning a pet bird was – and for some generations in China, still is – a status symbol. This dates back to the Qing dynasty. Wealthy individuals would build elaborate bamboo cages for their birds.
This custom that continues mainly among retired men in their later years. Silva says older Chinese people may not understand they are committing a wildlife crime, or grasp that numerous birds were killed in a trap for them to purchase a pet.
"This generation often lacked enough to eat growing up. Now with a little money, they have adopted the habit and custom 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
Along a riverside path in Beijing, a vendor has several small cages with chirping songbirds.
A separate individual stands outside a local market holding a bird cage covered by a dark cloth. He informs passers-by discreetly that his songbird is rare, worth nearly 1900 yuan.
This offers a view of an old Beijing where small unofficial traders have created their own market.
The area alongside the water stretches for several miles and on a sunny weekday morning, there were shoppers browsing everything from old trinkets to dentures.
Information suggested that protected birds could be bought in a nearby green space. The location was not concealed.
Loud music played from a speaker under the low trees where a group of elderly ladies were performing a fan dance. Close by several men, all over 50, had congregated with bird cages – some had multiple in their hands. Most were covered in black fabric.
But today there would be no sales because the police had appeared. They were questioning the bird owners and taking names. Defiant, one man said he was {taking his caged bird for a walk|simply exercising his
