With the help of Batloggers and Echometers, the NICHE Foundation collects sound recordings of bats at various locations (apart from regular fieldwork). This data will be donated to Observation International (Waarneming.nl, Waarnemingen.be and Observation.org).
 

Each sound recording is equivalent to a bat sighting (date, coordinates and time are automatically linked to the digital file) so that they can be imported as such. We now have a dataset of tens of thousands bat observations from Austria, Croatia, Curaçao, Cyprus, Czech Republic, Denmark, France, Germany, Hungary, Italy, Luxembourg, Malaysia, Marocco, Norway, Oman, Qatar, San Marino, Senegal, Singapore, Slovenia, Spain, Sri Lanka, Switzerland, The Gambia, The Netherlands, Tunesia, Turkey, United Arab Emirates, United Kingdom and United States.
