Wyoming Birds. 85 



487. 'Copvus cryptoleucus: White-necked Raven. 



"Rare so far as known. The Wyoming record is based 

 upon the observation of C. E. Aiken (Am. Nat. "VII, 1873, 

 16), Cheyenne, Wyoming. He also states in his article in 

 Pr. Bost. Soc, 1872, 203 : 'Very common along the base 

 of the mountains.' No other collector has found this 

 Raven in the state." (Knight.) On page 122 of "Birds 

 of Nebraska," by Bruner, this bird is mentioned and it 

 should be found in this state. 



499. Agelaius gubernator californicus: Bicolored Redwing. 



In The Auk for 1899, Vol. 6, page 341, Bond recorded the 

 capture of one bird, April 14, 1889. It is also mentioned 

 by Cook in "Birds of Colorado." This record by Bond 

 was published some years ago, before Knight's work was 

 prepared, but Knight did not record this species. 



500. Agleiaus tricolor: Tricolored Redwing. 



Sawyer reports it from near Laramie, but it is probable 

 that he should refer to fortis, which is so abundant in that 

 region. 



559. Spizella monticola monticola: Tree Sparrow. 



Reported by Percival, but should probably be referred to 

 ochraceae. 



563a. Spizella pucilla arenacea: Western Field Sparrow. 



The only record we have of this bird is by Blackwelder, 

 from the Teton region. See local list by Blackwelder. See 

 also Knight. 



581a. Melospiza melodia fallax: Desert Song Sparrow. 



Peabody reports this form, but it is quite ^probable that his 

 record should be for montana. If it occurs in Wyoming, 

 it is probably along the southern or southwestern region 

 only. Walker expected to find it at Green River, but found 

 only montana. 



585. Passerella illiaca illiaca: Fox Sparrow. 



Peabody caught one brief glimpse of a bird which he thinks 

 should be recorded as this species.
