 or on the ground underneath it, and so formed of sage-

 up wide-open bills

 mother bird becomes 

 practically invisible,

 coloring blend with 

 the lights and shadows of the 

 earth and leaves.

 brush form at least a

 on the side of the throat is enough to distinguish the 

 Sage Sparrow from the Bell," and " his long black tail 

 and its gently tilting motion are good long-range recog- 

 nition marks."
