Pigeons have been derided as rats with wings and shooed away everywhere from window ledges to public squares.
But this past March, a flock of half a dozen pigeons, strapped with tiny backpacks, carrying pollution sensors, were set loose from a rooftop in London’s Brick Lane. One of them also had a G.P.S. tracker.
The winged patrol will fly all over the capital and tweet back its readings. The project’s real purpose, though, is to raise awareness about air pollution.
