The Nuthatches and Titmice, Paridse. 



The chickadee, the common representative of the titmouse family, and 

 one of the most useful of all birds, is a great destroyer of hairy cater- 

 pillars. Not only does it eat caterpillars of all sizes, feeding them to 

 its young, but it destroys all forms of these insects, except, perhaps, the 

 eggs of some species. Too much cannot be said in favor of this most 

 useful and harmless bird. Both species of the nuthatch take these 

 larva? only as they come in their way on the trunks of the trees, and 

 not always even then. 



Tlie Thrushes, Turdidae. 



While the thrushes eat hairy caterpillars when they come in their way, 

 they do not, with the exception of the robin, appear to search them out.' 

 The robin seems to be in this way the most useful of all the thrushes. 

 The wood thrush and Wilson's thrush occasionally visit localities in- 

 fested by the caterpillars and eat a few, but the robin visits them fre- 

 quently and eats many. The thrushes eat mainly the larger caterpillars. 



The bluebird is useful in destroying most forms of these insects, but 

 as bluebirds are not plentiful in the infested region the opportunity for 

 observation has not been so good as in the case of some other species.
