  No one probably knows, as no blackbird has ever done it!
  
  There are birds that migrate very long distance around the planet, such as the Arctic tern, but they take months to get from the northern places like Canada to Antarctica
  
  I would have thought it would definitely take months and months, with lots of rest stops for food!
