TALKS WITH YOUNG OBSERVERS 315

 vicinity had the wren visited these little ones." 



Of all our birds, the wren seems the most over- 

 flowing with life and activity. Probably in this in- 

 stance it had stuffed its own young to repletion, 

 when its own activity bubbled over into the nest of

 incessantly. When its foster parent is a small bird 

 like " chippie " or one of the warblers, one would
