Ten pigeons, armed with air-pollution detectors on their backs, were released into the London sky on Wednesday to monitor pollution in the British capital.

Equipped with Global Positioning System (GPS) devices and pollution sensors to monitor nitrogen dioxide and ozone levels, the birds, dubbed the "Pigeon Air Patrol", were released from Primrose Hill in North London.

The data they collect can be followed on the website pigeonairpatrol.com, said Mr Romain Lacombe, founder of the French start-up Plume Labs, who started the project with Mr Pierre Duquesnoy of DigitasLBi.

London has recorded the highest levels of nitrogen dioxide in any European capital, and in 2014 was taken to task by the European Commission for not meeting standards.
