Constant developments in technology, both materials and methods, allow smaller and smaller animals to be radio-tracked for longer periods of time than was previously possible. Developments in electronic component miniaturization and battery chemistry are primarily responsible for this advancement. Approximately 30 years of field-use of radiotelemetry techniques have led to innovative procedures and uses of materials for the application of transmitters to animals. New technology such as satellite telemetry and recapture collars are only in their infancy and are not, at this time, appropriate for use in vertebrate pest research. Sophistication in receiving systems also allows more accurate and more complete data to be collected. This paper is not intended to be a review of telemetry devices on the cutting-edge of technology or non-field-proven developmental systems, but rather presents an overview of currently available, on-the-market technology appropriate for use by vertebrate pest researchers. As it is a review paper, not a research paper, it does not strictly follow the standard research paper format.
