North and Middle America, p. 336) refers this species to Zono- 

 trichia leucophrys leucophrys (Forster.). 



554 a. Zonotrichia leucophrys gambelii (Nutt.). 

 Gambei's Sparrow. 

 Migratory ; hut common. There have been so many 

 changes in the arrangement of the varieties of this species and 



of this genus, that more or less 

 confusion will doubtless re- 

 sult, and some of the data giv- 

 en here must be considered 

 tentative. Drexel reported 

 this variety from Fort Bridg- 

 er, and I have learned that 

 this has been passed upon by 

 Mr. Ridgway as a typical 

 form. Bond has also had Mr. 

 Ridgway identify four skins 

 as gambellii. Holden's skins 

 taken at Sherman belong to 

 this variety- Probably some 

 of the material collected or 

 published by Cones belongs 

 here. Dr. Jesurun has report- 

 ed sparrows under the name 

 Intermediate Sparrow, which 

 has been replaced by Gambei's Sparrow and they are included 

 here for that reason. Merriam has also included a Yellowstone 

 park record under intermedia which is probably gambelii. Wil- 

 liston also noted an abundance of what was then known as 

 Gambei's Sparrow, near Lake Como and in the Medicine Bow 

 mountains. These data have also been included under this 

 head.
