Radio telemetry is used by wildlife biologists to study animal movements. Animals wear a radio transmitter that gives off a silent signal which can be received by using a special antenna. By reading the signal, wildlife biologists can pinpoint which animal's radio is signaling, determine its exact location and follow its movements.

How does the Wildlife Division use radio telemetry?
Deer biologists put radio collars on deer to help determine their movements. They also use telemetry darts to help locate a deer that has been darted with an immobilizing drug.
Nonharvested wildlife biologists attach tiny radio transmitters to the backs of tree-roosting bats to help them find out where the bats spend the daytime hours. Biologists also use telemetry to study the movements of rattlesnakes and bog turtles.
The furbearer biologist uses radio telemetry to study the home range of raccoons. |
