CHIPPING SPARROW (Spizella Passerina) 



The chipping sparrow is a small, tame sparrow with a rusty cap and a 

 black line through the eye. It inhabits open areas in relatively dry environ- 

 ments with thinly scattered trees. Although it occurs in several habitat 

 types, it is most common in the fir-aspen complex. The chipping sparrow's 

 song consists of a series of rapid, monotonous chips. The song is most 

 often delivered from the outermost tip of a conifer branch. The nest of 

 this species is a neat, hair-lined cup, most often built on the branch of a 

 conifer. The eggs are light blue, richly flecked with rust. Chipping sparrows 

 are common breeding residents in both Yellowstone and Grand Teton.

WHITE-CROWNED SPARROW (Zonotrichia leucophrys) 



This handsome sparrow with a distinctive black and white crown striping 

 is primarily a bird of the willow thickets of mountain meadows and lakes 

 in Yellowstone and Grand Teton. The song of this species is a series of 

 beautifully whistled notes followed by buzzing trills. When distressed, 

 the white-crown utters a metallic "pink." Irpmature white-crowned spar- 

 rows have brown head stripings and pinkish bills. The nest of this species 

 is a well-lined cup of grasses placed on the ground or in the fork of a low 

 willow or conifer. The eggs are spotted and blue-green. This species is 

 one of the most common breeding birds in Yellowstone and Grand Teton.
