larger. The egg is, in fact, much like that of the Song Sparrow, being 

 ])ale bkiish, speckled and blotched with diHereut shades of reddish-

 River and Yukon region, show the same wide range of variation that 

 the Song Sparrow's egg displays, being thus different from the eggs of 

 other /:<2^izella'. The uiditication varies, the nest being placed indiffer- 

 ently on trees, bushes, or the ground.
