Pigeon Air Patrol

Asmall flock of pigeonshave been given tiny backpacks to monitor air pollution in London.

The project was dreamt up byPlume Labs, a company focused on the environmental problem, and the marketing agencyDigitasLBi.

The rucksacks are fitted to the birds using small fabric vests, and the sensors inside are able to measure nitrogen dioxide and ozone levels. Only 10 birds are in flight at any one time, so the amount of data being collected is pretty small. However, it's still a creative way of analysing the air that millions breathe in every day in the capital.

If you're interested in tracking the birds' progress, a live map is currently available on theproject's microsite. Alternatively, you can tweet the@pigeonairaccount on Twitter for a quick summary of a specific borough or neighborhood.

The project is a three-day affair, designed to attractnew beta testersfor a wearable pollution monitor built by Plume Labs. As such, the new "Pigeon Air Patrol" feels more like a marketing campaign than an evolution in air pollution management. Still, it's neat to know that there are birds in the sky with backpacks -- and maybe, just maybe, there's scope to expand and refine the idea if these experimental test flights take off.
