Now biologists can get much more accurate information about endangered bats, birds and insects. A new recording system, developed at the University of Southern Denmark, has revealed many previously unknown and highly valuable details about bats.
Gone are the days where biologists had to sit in tents for several days with binoculars and infrared cameras in order to register endangered animals. A new monitoring system, which for two months has continuously recorded bat activity on the roof of a garage at the University of Southern Denmark has proven so effective that it has revealed two bat species that scientists did not believe lived in the area.
A growing concern about endangered species has created a need for a system to effectively monitor the endangered animals. Bats are endangered, and they live right here in our backyard at the university. Also the university is about to undergo major construction work, which will triple the number of buildings in the area. It is an obviously good idea to monitor how this will affects our bats, explains Professor John Hallam from Maersk Mc-Kinney Moller Institute University of Southern Denmark.
The researchers placed the new recording equipment about five meters above the ground on top of a garage building where bats often fly by.
We got two months of continuous recording from the site. It would be impossible for one person to sort the recordings, but the automatic processing of recordings identified 115,000 bat sounds. Using the automatic processing, we end up with only a small part of recordings in need of humane processing, explains John Hallam.
This is the first recording system, which can monitor a range of insects, birds and bats effectively. And it can have major implications for how effectively biologists in the future determine the range of animal species.
