Most people are aware of the fact that years of pollution is taking its toll on our planet and the creatures on it, but when it comes to birds it is sometimes difficult to get an accurate estimate of exactly how badly particular species have been affected. That is all about to change, thanks to a new voice-recording method that has been developed specifically to assist bird conservationists.
Dedicated volunteer bird-watchers covered around 3,500 routes across the United States, Canada and Alaska as participants in the North American Breeding Bird survey. This data is being used by the Montana State University (MSU) in a study that examines biodiversity across North America. Together with additional information gathered by a satellite sensor developed at the university, researchers are gaining tremendous insight on issues such as conservation and land use.
