“PigeonBlog provides an alternative way to participate environmental air pollution data gathering. The project equips urban homing pigeons with GPS enabled electronic air pollution sensing devices capable of sending real-time location based air pollution and image data to an online mapping/blogging environment. Pigeonblog is a social public experiment between human and non-human animals.”[2]
