VI. Regular Transients. Birds which winter south of 

 our limits, breed north of us, and pass through our territory 

 in spring and fall, are transients. The regular transients 

 occur every year. A few of them breed very locally, and 

 others winter very locally or occasionally. These excep- 

 tional cases, however, are always much more abundant and 

 widely distributed as transients, and are consequently in- 

 cluded here.
