The redstart (Setophaga ruticilla) represents a notable case of a 
wide migration route, although even in the southern United States 
this is much narrower than the breeding range (fig. 19). These birds,

FIGURE 19.—Distribution and migration of the redstart. An example ofa wide migration route, since birds 
of this species cross all parts of the Gulf of Mexico, or may travel from Florida to Cuba and through the 
Bahamas. Their flyway thus has an east and west width of more than 2,000 miles. For migration paths 
of greater or less extent see figures 16, 17, and 18. ; ; 
however, cross all parts of the Gulf of Mexico and pass from Florida 
~ to Cuba and Haiti by way of the Bahamas, so that here their route 
has a width of about 2,500 miles. 
In the following, the discussion of the principal routes of North 
American birds relates chiefly to the fall migration, for, except as 
otherwise noted, the spring flight generally retraces the same course.
