RFID Is Helping Penguins At The Cincinnati Zoo Swim More

The Cincinnati Zoo & Botanical Garden's Little Blue penguins are swimming more thanks to RFID technology.

The smallest penguins in the world have their own exhibit at the Cincinnati Zoo.

For decades the zoo has been working on different strategies to get them swimming more, including teaching the penguins to play with balls and introducing food in the water.

Antennas now provid  data on how long each penguin is swimming and who their friends are.
