•>■ Mr. W. Sclater (MS.) thinks the southern examples are " more dull and 

 neutral," and that the northern ones are therefore separable. The latter form a 

 resident race in Venezuela, Colombia, etc., and have no connection with North 

 American birds. As is the case with so many other species the tropical zone birds 

 are small and resident, and the temperate North American and S. American races 

 larger and migratory. It does not, however, seem possible to separate the S. Ameri- 

 can races from one another.
