Sometimes a bird watcher will see familiar friends if travelling to Central or South America for a birding holiday.
* The golden plover breeds in North America, but flies over 2,400 miles to winter in South America.
* The artic tern flies over 10,000 miles during their migrations.
Many birds that live in tropical climates also migrate briefly to the north, spending just a few months out of the year before returning. If you are an avid bird watcher, try to plan your trip according to the migration of a specific species. See your old friend in their summer or winter home!
