 Pieces of pork rind or of suet tied to a limb of a tree will tempt 

 the appetites of woodpeckers, nuthatches, and chickadees. 



Water is needed by birds both to drink and for bathing, of 

 which they are very fond. This is especially true during the 

 hotter days of summer. If there is a water tap on the lawn, a 

 very good bird bath can be constructed by making an inden- 

 tation a few inches deep and three feet long and lining this with 

 round stones set in clay (Fig. 265). In such a place as this 

 many different kinds of birds make their toilets on warm summer 

 days.
