 six inches. A winter visitor in the interior 

 valleys of California. Birds from central Cali-

 slight. 



Savanna Sparrow Group. Sparrows of the open 

 fields and seaside, with rather long, sharp beaks, 

 short tail, general streaked coloration, and often 

 some yellow about face or over the eye. There

 ensis (Gmel.). 



This type species of the group is brownish gray

 light gray line down the middle of the head, 

 separating two darker stripes; breast whitish, 

 streaked with brown. This northern race, 

 which breeds in Alaska, is large in size (about 

 six inches long) and has a large bill. It is 

 found in the mountainous portions of Calitornia 

 during the winter months. The Western Sa- 

 vanna Sparrow (^Ammodramus sandwichensis 

 alaudinus (Bonap.) is the common race inhabit- 

 ing the fields of California, especially in the 

 interior districts. It has a slightly browner 

 shade of coloration than the preceding bird. 

 Bryant's Marsh Sparrow (^Ammodramus sand- 

 wichensis bryanti Ridgw.) is a decidedly darker 

 form, with a more distinct yellow line over the 

 eye. It is the variety which breeds in the 

 vicinity of San Francisco Bay.
