The names reflect the geographic native habitats of Magellanic penguins and are derived from Isla Calista of the Falkland Islands and Carmen, Argentina.

Calista and Carmen can be scene in Shedd’s Polar Play Zone periodically, where they were recently introduced to the habitat and the rest of the colony.
