Auditory surveys are instrumental for a range of absent–present studies of vocal species. However, they are generally time and resource-intensive. To keep the cost of time and travel associated with auditory surveys at a minimum, we have developed a device, the FrogPhone, for remote monitoring. The system simulates the main features of a phone device working within the 3G/4G Cellular network frequencies or a satellite network. By dialling up the invention, the user can conduct an auditory survey in real time and obtain environmental data (e.g. water and air temperature) through a text message sent to his mobile phone. The FrogPhone allows extending auditory survey projects while decreasing overall project costs and enable surveys that previously were too costly.
