SAVANNAH SPARROW (Passerculus sandwichensis] 



Small, shy, and lacking distinguishing markings, the savannah sparrow is 

 easily overlooked. A heavily streaked sparrovi^ with a narrow, yellowish 

 streak over the eye, this species inhabits areas of short grasses or sparse 

 vegetation, and the grassy fringes of marshes. The savannah sparrow usual- 

 ly remains on or near the ground, and the best evidence of its presence is 

 often its weak, lispy song. When flushed, the savannah sparrow flies a short 

 distance before disappearing back into the grasses. The nest of this spe- 

 cies is a simple, grass-lined hollow on the ground. Savannah sparrows are 

 common breeding birds in both Yellowstone and Grand Teton.
