Penguin reunites with his best human friend

Story highlights

  • A man in Brazil helped save a penguin when it was covered in oil
  • Ever since then the penguin returns each year to reunite with him

(CNN)You may have heard a fantastic story about how a penguin swims 5,000 miles every year to see the man who saved his life.

It's a heartwarming story that's almost too good to be true.
This story has been circulating on social media throughout this week. While there's some truth behind it, it's also filled with plenty of misinformation.
    CNN reached out to biologist Joao Paulo Krajewski, who documented this story for Globo TV, a media network in Brazil, in February.
    "I am happy to see the story I presented spread all over the world, but I am also concerned by the amount of misconceptions spread and by some articles changing my statements," Krajewski posted on Facebook.
    Ever since Krajewski's story was published online on March 6, there have been duplicate reports that the penguin travels over 5,000 miles to visit the man, but Krajewski says this is false.
    "It is a beautiful story because the penguin was in very bad shape and about to die when it was first found and the men gave him a second chance," Krajewski told CNN.
    Here is the real story behind Dindim, the traveling penguin from South America.
    In May 2011, Dindim was caught in an oil spill. The Magellanic penguin could barely move. Joao Pereira de Souza found the helpless creature in his backyard, which opens up onto Proveta Beach in Rio de Janeiro State, Brazil.
    The 71-year-old retired mason cared for the penguin by washing the oil off of Dindim's body and fed the bird sardines over the next few days.
    Dindim stayed outside while Pereira de Souza nursed him back to health.
    Magellanic penguins live off the coast of Patagonian South America. They can live in the ocean as long as five months at a time before returning to the coast. These penguins are known to breed off the coast of Argentina, but have been spotted occasionally as far north as Rio de Janeiro.
    When Dindim seemed strong enough, Pereira de Souza took him to a nearby island and released the bird into the sea. Later that day, Pereira de Souza heard squeaking in his backyard. Much to his surprise, he saw the penguin had returned and was calling out for him.
    Magellanic penguins are known for their loud, mournful calls, similar to those of a donkey.
