Ever since a 71-year-old Brazilian man rescued a struggling penguin, he's been receiving regular visits from his feathered friend. Joao Pereira de Souza, a retired bricklayer, lives ... just off the coast of Rio de Janeiro. In 2011, he spotted a starving Magellanic penguin drenched in oil on the beach near his house. Naming the penguin Dindim, Pereira de Souza fed him every day until he was strong enough to leave, according to a video from the University of Rio de Janeiro. But the penguin refused to go. Pereira de Souza decided to row a boat out into the water and drop Dindim off to encourage him to swim home. But when he rowed back to shore, he found the penguin waiting for him. "He stayed with me for 11 months and then, just after he changed his coat with new feathers, he disappeared," Pereira de Souza told TV Globo, a Brazilian TV network. Magellanic penguins regularly swim thousands of kilometres a year to breeding spots on the coast of Argentina and Chile. From time to time, penguins show up in warmer Brazilian waters. Many of Pereira de Souza's friends thought that when Dindim finally left, that was it for the human-bird friendship. But a few months later, Dindim returned and found Pereira de Souza. He visits for about four months, a ritual kept for the last five years. "He arrives in June and leaves to go home in February, and every year he becomes more affectionate," Pereira de Souza told TV Globo. De Souza appears to be the only person who can get near Dindim. If others try, he pecks them or waddles away.
