The Birds of El Paso County, Colorado 557 



Astragalinus tristis tristis. Goldfinch. "Wild Canary." 



Summer resident ; common. 



It is somewhat difficult to separate the records and occur- 

 rence of this from the following subspecies, as a sufficient series 

 of specimens for the purpose is lacking. With the exception 

 of the few which sometimes spend the winter the Goldfinches 

 arrive early in May for the summer and are quite common 

 over the County below 7,000 feet. 



Astragalinus tristis pallidas. Pale Goldfinch. 



Summer resident ; common. Found occasionally in win- 

 ter. ' 



Aiken considers that the Goldfinches which spend the 

 winter in the County are all pallidus, and that the summer resi- 

 dents along the foothills are mainly this species, while most of 

 the typical form are found toward the eastern portion of the 

 County. More collecting of specimens is, however, necessary 

 to fully settle these points. Summer birds soon lose the paler 

 edges of the feathers by abrasion and are then not noticeably 

 different from the preceding form. 



Astragalinus psaltria psaltria. Arkansas Goldfinch. 



Astragalinus psaltria arizonae. Arizona Goldfinch. 



Astragalinus psaltria mexicanus. Mexican Goldfinch. 



Summer resident ; common. Typical psaltria usually ar- 

 rives the third week in June; extremely early dates are April 

 21, 1900, and May 13, 1898, and specimens taken at these dates 

 were still in their winter dreSs. Most of them leave in Sep- 

 tember and October ; an unusually late date is that of a speci- 

 men from Beaver Creek, Fremont County, November 11, 1872. 

 This is still in summer dress.
