Disadvantages of being radio-collared

Radio-tracking has proved to be an invaluable method of studying animal migration. Radio-tracking involves attaching a transmitter to the body of the animal, that send out radio signals just like a radio station. These signals are then tracked by a receiver held by the scientist who follows the animal in a truck, ATV or an aircraft. The transmitters may either be placed externally, like radio-collars, rings and labels, or internally using surgical implanting procedures.
