PigeonBlog is a project by Beatriz da Costa with Cina Hazegh and Kevin Ponto.
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.
