HYPOTHETICAL LIST [607] 



Baird's Sparrow: 



Ammodramus bairdi (Audubon) 



THIS BIRD has been admitted to the Oregon lists on Bendire's (1877) 

 statement that he took a supposed nest with four eggs at Camp Harney 

 on May 2.4, 1876. In view of the fact that this is a bird of the Great 

 Plains country and has never been taken in our section of the West, we 

 are placing it in the hypothetical list. 



Western Field Sparrow: 



Spi^ella pusilla arenacea Chadbourne 



THIS is another species that is in the Oregon list on the basis of Ellis F. 

 Hadley's statements (Woodcock 1902.), who found a nest containing 

 three eggs, June 14, 1900, near Dayton. In view of the fact that no 

 specimens of the bird were taken and of the further fact that this species 

 has never been taken west of the Rockies, we are placing it in the hypo- 

 thetical list.
