The whole scheme works thanks to a small GPS tracking device attached to the penguin. Sirtrack, the device’s maker, is keen to point out that it has been specially designed not to impede the penguin’s swimming ability and weighs less than 1% of the bird’s weight. Twice a day, the device activates and broadcasts location data for three hours at a time, presumably to increase the onboard battery life.
So far, Happy Feet seems to be doing quite well on his southward journey, but we can only hope that he doesn’t get thrown off course again.
