This week, trainers at the Shedd introduced sticks and stones necessary for nestbuilding into the rockhopper and Magellanic penguin habitat.

Over the next few weeks, the male birds will carefully select and arrange their nests to attract a female mate.

If they're successful, eggs could be seen by the end of April into May!
