Different types of birds take routes of widely varying lengths.
Some round-trip migrations can be as long as 44,000 miles, equivalent to almost two round-the-world trips. Others are much shorter.
Some birds even migrate on foot.
Many cover thousands of miles and move back and forth between continents.
