Astragalinus psaltria hesperophilus Oberholser. 
Green-backed Goldfinch. 
A very few individuals were noted in the upper Santa Ana, 
where a specimen was taken as high as Fish creek, 6500 feet, 
June 23, 1905; and a nest was found on the mesa above the 
mouth of the South Fork, at about 6400 feet altitude, July 9, 
1906. This is of note as being well within the Transition zone; 
for the bird according to my experience is ordinarily a strictly 
Upper Sonoran species. The date is also noteworthy, suggesting 
that the pair may have nested lower down earlier in the season ; 
for no green-backed goldfinches were previously seen in the local- 
ity. The nest was situated nine feet above the ground in a black 
oak, and contained four fresh eggs of the usual type. 
In the vicinity of Seven Oaks several of these goldfinches 
were seen. In the lower Santa Ana, below the confluence of Bear 
creek, the species was numerous June 11 and 12, and several 
nests were found along the canon. It was also noted in July and 
August in the lower Mill creek ecafon. At Cushenbury springs, 
at the desert base of the. mountains, this was a fairly common 
bird August 10 to 14, 1905. Four skins of this species were 
taken. 
Astragalinus lawrencei (Cassin). Lawrence Goldfinch. 
This bird ranged up through the Transition zone in several 
portions of the region. On the upper Santa Ana from Seven 
Oaks as high as Fish creek, 6500 feet altitude, it was commonly 
noted; and on June 30, 1905, one individual was seen as high as 
the South Fork cienaga, 8500 feet. The species was undoubtedly 
nesting along the Santa Ana; juvenals became common in July, 
1906, and on July 26, 1907, I found a brood of one-third-grown 
young in a sage clump. In the pinon belt around Baldwin lake 
and at Doble, 6700 to 7000 feet altitude, several were seen in 
August. Seven specimens were obtained. 
Spinus pinus (Wilson). Pine Siskin. 
Pine siskins were more or less abundant from the lower 
Transition zone up into Boreal. They were common along the 
upper Santa Ana above Seven Oaks and in Fish ereek and South
