Radio telemetry has provided the basis of much of what is known about animal movements.  The technique is simple - capture an animal, and attach to it a lightweight radio transmitter, then following its release, track its movements using a handheld receiver programmed to the frequency of the transmitter.  Though labour-intensive and limited mostly to documenting short-distance movements, it is a valuable method in many situations, especially where other techniques may not be feasible.  Further information about radio telemetry techniques will be described under the project outlines for MRF research involving this method.
