PRINCIPAL Migration routes 



T Fig. 4. Distribution and migration of the golden plover ( Charadrius dominkus). In fall it 

 Hies over the ocean from Nova Scotia to South America, 2, -100 miles — the longest known flight 

 of any bird. In spring it returns by way of the Mississippi Valley. Thus the migration 

 routes form an enormous ellipse, with a minor axis of 2,000 miles and a major axis stretching 

 S,000 miles from Arctic America to Argentina. (See p. 17.)
