What would you like to monitor? Ultrasonic Vocalization, Position, other parameters of the marmoset ?
We have equipment (SONOTRACK) which can record and analyze the ultrasonic vocalizations of the Cebuella pygmaea. Although it is designed for use with laboratory rodents, it can record all animals that vocalize in the ultrasound frequency range. We have also mobile versions of the equipment.
Depending on your requirements different batteries can be applied which enable shorter or longer measurement periods.
thank you for your help. However, we are aiming to monitor the position of the individuals, preferably by using a technique, such as radio telemetry, that allows us to control the animals from the sanctuary as the release site is of difficult access.
