Wildlife radio telemetry

It is often used to obtain location data on the animal's preferred habitat, home range, and to understand population dynamics.

[2] Recent advances in technology have improved radio telemetry techniques by increasing the efficacy of data collection.

Transmitters are available in a variety of forms and consist of an antenna, a power source, and the electronics required to produce a signal.

In some species of fish that have ceased feeding, transmitters are inserted inside the animal's body cavity as a means to minimize the stress of tagging.

A harness loop antenna design, implemented for small birds, involves a transmitter being wrapped around the body.

The receiver produces a tone that increases in loudness or has a visual signal strength indicator that pulses as the operator approaches the transmitter.

[1] Global positioning tracking involves a receiver that picks up signals from satellites to determine the location of a transmitted animal over time.

Global positioning tracking is useful for migrating animals because their locations can accurately be determined, regardless of the distance they are from the operator.

Many of these systems implement platform terminal transmitters (PTT) that send electromagnetic signals to Argos equipment found on satellites.

[1] Technologies developed by companies such as Wildlife Drones have expanded these capabilities, enabling data collection using drone-based systems.

It is important that any negative effects of attaching radio-transmitters to animals are reported to improve methods and reduce harm to individuals in future studies.
