SPOTTED TOWHEE 



The Spotted Towhees of western North America {Pipilo maculatus) have 

 been divided into seven forms; one is confined to Mexico, one to southern 

 Lower California, and one to the islands off the coast of southern California. 

 A fourth form, the San Diego Towhee, is nearly, if not quite, non-migratory 

 over a large part of California, while a fifth form, the Oregon Towhee, occurs 

 on the coast from British Columbia to southern California, and is migratory 

 at the two extremes of its range, but no definite statement can be made of 

 its dates of migration. The other two forms, the Arctic and the Spurred Tow- 

 hees, occupy the Rocky Mountains from southern Canada south to Mexico 

 and the western part of the plains. They are both strictly migratory, but it 

 is not possible to separate the migration records of the two forms.
