The research team at the University of California in Irvine (USA) will use 20 pigeons to monitor air pollution in San Jose, California.
Each bird will be worn on a special backpack, which contains a GPS satellite receiver, air pollution sensors and a mobile phone.
Air quality data will be sent automatically by text message to a special blog on the Internet, while images are transmitted from above through a tiny video camera worn in the chest of birds. These birds will be released into the sky to perform the task on August 5-8.
