The ability of birds to navigate their way back to their nests, often more than thousands of miles each year, is fascinating. Arctic terns, which have the longest migration distance known, travel from their Arctic breeding grounds to overwinter on the Antarctic coast: an annual roundtrip of over 40,000 miles (64,000 km).
Although we still don't know the complete story, there are some very strong clues to how birds navigate. But how mammals (including humans) navigate is relatively unexplored. Recent research is however giving some very interesting insights.
