Technical Summary

This technology consists of a computer-controlled pellet dispenser with a microchip reader. An AVID 6" ring antenna is located directly in front of the dispenser opening and scans the ID of individual members of a group that reach into the pellet dispenser cup. Microchips must be embedded into the forearms of each animal in order to allow identification of an individual in a group.

As the monkey's hand reaches under the ring antenna, a single pellet drops into a custom made cup through a clear polypropylene tube. A computer records the ID of the individual and outputs a log of ID numbers and the time they were recorded using a basic software program. The computer can be controlled remotely using VNC software.
