Figure 10. — Distribution and migration of the scarlet tanager. During 

 the breeding season individual scarlet tanagers may be 1,900 miles 

 apart in an east-and-west line across the breeding range. In migra- 

 tion, however, the lines converge until in southern Central America 

 they are not more than 100 miles apart. For migration paths of 

 other widths see figures 9, 1 1 , and 1 2. 



few actual breeding records of the species are available, but these are 

 sufficient to indicate that the breeding range is in the strip of country 

 characterized by more or less stunted timber just south of the limit of 

 trees. When it begins its fall migration, this species necessarily covers 

 the full width of its breeding area. Then it proceeds almost directly
