Mentioned by the naturalists of the Expedition as a bird of Oregon, 

 and by Dr. Pickering as observed to be common at various points in 

 California. Specimens in the collection are from the former country. 



The name above given we have no doubt is applicable to the bird 

 now before us, though Swainson's description is not in all respects satis- 

 fiictory. We have no doubt either that all the names above are syno- 

 nymes. >
