Radio telemetry is the technique our research team used to track Adelie penguins while feeding in the Ross Sea.(tea.rice.edu/wille/1.6.2000) When penguins are tracked using this method, a small radio transmitter is carefully taped to the feathers on the lower back of the bird. This transmitter is about 4 cm long and has an antenna that extends another 15 cm to the penguin?s tail. Each transmitter is set to its own special frequency so that by tuning our receiver to that frequency, we can locate an individual bird. This is much like tuning into your favorite radio station. To obtain the three data points needed for triangulation, our team had people at three separate stations. At the same time each day, we tracked each penguin to its feeding ground. In this activity, you will use the raw telemetry data obtained by the research team, to determine the location of Adelie penguin feeding areas.
