SPIZELLA PASSERINA ARIZONAE Coues 



Western Chipping Sparrow 

 Contributed by R. Roy Johnson 



Habits 



The western race of the chipping sparrow differs from the nominate 

 eastern subspecies chiefly in being slightly larger in size and paler in 

 color, differences that are seldom discernible in the field. It resembles 

 its eastern relative very closely in practically all aspects of habits and 

 behavior. A bu-d of wide range and great adaptability, it is essentially 

 an inhabitant of woodland clearings. 



In Washington state, Jewett, Taylor, Shaw, and Aldrich (1953) 

 consider it a "common migrant and summer resident from April to 

 September in open timber and brushy situations from Upper Sonoran 

 to Hudsonian Zones." In Oregon, Gabrielson and Jewett (1940) 

 state that it "is one of our most abundant summer resident birds and 

 is one of the famUiar lawn birds of the valley towns throughout the 

 State, where it may be found hopping about in the grass, collecting 

 insects and seeds to feed the youngsters in the hairlined nest built in 

 some low-hanging bough. It is equally abundant and unsuspicious 

 about the mountain meadows of the Cascades and in the parklike 

 vistas of the yellow-pine forests of the Blue Mountains, where it is 

 present at aU but the highest elevations." 



Of its status in California, Grinnell and Miller (1944) say: "Summer 

 resident, migrant, and winter visitant; in some lowland localities in 

 southwestern section present throughout year. Appears in areas of 

 summer residence in April, or at higher elevations in May; leaves in 

 September and early October. Usually common on nesting grounds, 

 sometimes abundant; in winter sparse to fairly common; numbers
