176 PASSERES: Perching Birds 



WILLOW GOLDFINCH 



(529b. Astragalinus tristis salicamans) 4f in. 



Male: Bright yellow, with black cap; wings and tail black, 

 white-marked; yellow of back usually blotched with ashy, in 

 winter nearly obscured by it. 



Female: Olive-brown above; dull yellowish below; wings and 

 tail dull black. 



Immature male: Like female, but yellower; crown-patch 

 absent. 



Its canary-like " tweet" and song, as well as color and shape, 

 justify the popular name, "Wild Canary." 



GREEN-BACKED GOLDFINCH 



(530a. Astragalinus psaltria hesperophilus) 41 in. 



Male: Wholly bright yellow below; dull greenish above, with 

 black cap, wings, and tail. Contrast of dull upper parts with 

 the brilliant yellow is very striking. 



Female: Olive-green above; yellowish below. A very obscure 

 bird. 



Call: A weak "se-e-e-ep," totally unlike that of the Willow 

 Goldfinch. Song less canary-like. 



LAWRENCE GOLDFINCH 



(531. Astragalinus lawrencei) 4 in. 



Male: Cap, chin, and front of cheeks black; body dark gray; 

 breast, rump, and wings extensively greenish yellow. 



Female: Browner; black and yellow absent; edges of wing- 

 feathers greenish. 



Habits like those of the other Goldfinches. A seed-eater al- 

 most exclusively. 



Song resembles that of the Willow Goldfinch.
