yet in summer they destroy quantities of insects which they 

 feed to their young. 



In the spring they go north to Canada or seek the summits 

 of the Alleghanies for their nesting places. The note of these 

 birds when disturbed is tsip, tsip, which may be followed by a 

 low, soft song when their fear has passed off. 



Though severely plain in appearance, they are very inter- 

 esting birds for they come to enliven the winter time when 

 most of the other birds have gone far south. Their gentle, 

 cheery ways help to make them favorite visitors.
