Until the advent of modern techniques it was almost impossible to achieve. Scientists now use a mix of old and new methods to track animals’ movement, including GPS and satellites, VHF radio transmission, and trapping and banding.  Case studies include: loggerhead turtles off the coast of Florida, elephant seals in the North Pacific, ringing of small birds in California.
