Data collecting is for the birds

Beatriz da Costa, assistant professor of informatics at the University of California, Irvine, holds a homing pigeon use as part of her PigeonBlog exhibit going on this week at ZeroOne San Jose, a San Jose, Calif., festival held in conjunction with the annual International Symposium of Electronic Art. Pigeons in the project carry packs equipped with GPS-enabled electronic air quality sensing devices that send real-time air pollution and image data to an online map.
