Pigeons Are London's Newest Pollution Fighters

Pigeons in London have a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.

"The problem for air pollution is that it's been largely ignored as an issue for a long time," says Andrea Lee, with the London-based environmental organization ClientEarth. "People don't realize how bad it is, and how it actually affects their health."

London's poor air quality is linked to nearly 10,000 early deaths a year, Lee says, citing a report released by the mayor last year. If people were better informed about the pollution they're breathing, she says, they could pressure the government to do something about it.

Nearby, on a windy hill in London's Regent's Park, an experiment is underway that could help — the inaugural week of flights by the Pigeon Air Patrol.

It all began when Pierre Duquesnoy, the creative director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, from France, chose the problem of air pollution.

"Basically, I realized how important the problem was," he says. "But also I realized that most of the people around me didn't know anything about it."

Duquesnoy says he wanted to better measure pollution, while at the same time making the results accessible to the public.

"So," he wondered, "how would we go across the city quickly to try to get as much data as possible?"

Drones were his first thought. But it's illegal to fly them over London.

"But pigeons can fly above London, right?" he says. "They live — actually, they are Londoners as well. So, yeah, I thought about using pigeons. And not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low."

His next task was to link up with a pigeon racer and his flock. That's when Brian Woodhouse came into the picture. He's a member of the Royal Racing Pigeon Association. He's kept pigeons for about 65 years.

Woodhouse has brought to the park a wicker cage holding seven of his racing pigeons. The birds will be fitted with pollution sensors and released in different parts of the city all week. The readings are analyzed to inform Londoners about their air quality.

Woodhouse says pigeons are perfect for the project.

"I liked the sound of it," he says. "I thought it was an extremely good idea, knowing that the pigeons in the First World War and the Second World War used to fly with messages, vital messages, for our troops and allies."

Today, pigeons can continue to bring vital information, Woodhouse says.

He and Duquesnoy begin attaching tiny Velcro harnesses around the pigeons' bodies. Each little backpack holds a pollution sensor weighing less than an ounce, developed by Plume Labs, an aptly named Paris tech startup. The sensors measure carbon monoxide and other air pollutant levels.

"These little sensors track your exposure to nitrogen dioxide, to ozone, to these gases that impact your health," says Romain Lacombe, Plume Labs' founder and CEO. "And that's the technology we're going to fly on the back of a pigeon through London today."

Lacombe says his company has developed a mobile app that tracks pollution in about 300 cities, so that residents can adapt their outdoor activities if the air is toxic. Londoners can get live readings from the Pigeon Air Patrol through Twitter or on a website devoted to the project.

So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city's air.

KELLY MCEVERS, HOST:

Pigeons in London have a bad reputation. One of the city's mayors famously called them flying rats. And many Londoners accuse them of causing pollution with their droppings. But the birds are now being used to measure another kind of pollution - air pollution. NPR's Eleanor Beardsley reports.

ELEANOR BEARDSLEY, BYLINE: That's one of London's double-decker buses belching out exhaust fumes during morning rush hour. Andrea Lee works with environmental organization Client Earth. The group has taken the British government to court for what it says are illegal pollution levels in the city.

ANDREA LEE: Mayor of London released a report last year that showed that up to 10,000 early deaths are being caused each year from exposure to air pollution in London alone.

BEARDSLEY: Lee says if people were better informed about the pollution they're breathing, they would pressure the government to do something about it.

Nearby on a windy hill in Regent's Park, the pigeon experiment is underway. It all started with a contest sponsored by the London Design Festival - how to solve a world problem using Twitter. Frenchman Pierre Duquesnoy won the contest and chose pollution.

PIERRE DUQUESNOY: Basically, you know, I realized how important the problem was. But also, I realized that most of the people around me didn't know anything about it.

BEARDSLEY: Duquesnoy says he wanted to better measure pollution and use Twitter to make the results more accessible to the public.

DUQUESNOY: So how would we go, you know, across the city quickly to try to get as much data as possible?

BEARDSLEY: Drones were his first thoughts, but there are restrictions about flying them over London.

DUQUESNOY: But pigeons can fly above London, right. Actually, they live - they are Londoners as well. So, yeah, I thought about using pigeons - and also, not just street pigeons, but racing pigeons because they fly pretty quickly and pretty low.

BEARDSLEY: So the next test was to link up with a pigeon racer and his flock.

BRIAN WOODHOUSE: I'm Brian Woodhouse, a member of the Royal Racing Pigeon Association in Great Britain. I've kept pigeons for about 65 years now.

WOODHOUSE: They love pigeons.

BEARDSLEY: Woodhouse has brought a wicker cage containing seven of his pigeons out to Regent's Park. Birds are being fitted with pollution sensors and released in different parts of the city. The readings are analyzed to help determine the city's air problems. Woodhouse says pigeons were vital carriers of information in times of war, and now they can help with the battle against pollution.

WOODHOUSE: And I like the sound of it. I thought it was an extremely, really good idea, knowing that the pigeons in the first world war and the second world war used to fly with messages - vital messages for our troops and allies.

That's the first wing done.

BEARDSLEY: Woodhouse and Duquesnoy begin attaching tiny harnesses around the pigeons' bodies. The little backpacks weigh less than an ounce and hold a pollution sensor developed by tech startup Plume Labs. Romain Lacombe founded the company.

ROMAIN LACOMBE: These little sensors track your exposure to nitrogen dioxides, to ozone, to these gases that impact your health, and that's the technology we're going to fly on the back of a pigeon through London today.

BEARDSLEY: Londoners can get live pollution readings from the Pigeon Air Patrol through Twitter or on the project's website. Now, the pigeons are suited up and ready to go.

WOODHOUSE: OK. One, two, three - off you go. There it goes.

BEARDSLEY: So now it might be time for Londoners to have more respect for their pigeons. The birds may just be helping improve the quality of the city's air. Eleanor Beardsley, NPR News, London. Transcript provided by NPR, Copyright NPR.
