A bird with a backpack! Meet a member of London's Pigeon Air Patrol, a flock of "superbirds" who are measuring nitrogen dioxide in London.

The team of 10 trained pigeons is taking to the skies strapped with 25-gram sensors to measure the harmful emissions not always visible to the naked eye and are tweeting the results. (Courtesy Twitter/Pigeon Air Patrol) #pigeon #london
