In 2001, a bricklayer living on the southeast coast of Brazil was met with a surprise outside of his beach shack – a Megallanic penguin lying at his doorstep, covered in oil. After cleaning and caring for the penguin, it returned to sea, and was presumably gone forever. But since then, the penguin nicknamed JingJing has returned year after year to visit his savior while feeding in the warmer waters off Brazil before migrating back to the breeding grounds off southern Argentina. It’s a remarkable friendship that would make anyone wonder about the sentience of these brilliant little birds.
