eggs is a characteristic habit of the chickadee, and thus makes the bird one ot the 

 most effective destroyers of insect pests. Between 200 and 300 eggs of the fall 

 canker worm have been found in the stomach of a chickadee, and 450 eggs of plant 

 lice in that of another. They are of especial value in an orchard. The Kinglets 

 are also useful birds, resembUng the chickadees in their habits. 



The Thrushes 



The thrushes are migratory birds, two species of which the Robin , Planestictus 

 migratorius migratorius, and the Bluebird, Sialia siahs sialia, are well known. 

 The others are found in wooded regions and are unknown except to the lover of 

 birds or their songs. Both the robin and the bluebird destroy many noxious insects 

 that infest the cultivated fields. The robin also is fond of fruit, as is well known, 

 but pays well for the cherries taken by the insect pests that it devours. 



Of the woodland thrushes, the Hermit Thrush is the best known and the 

 most common. All are noted songsters, but the hermit in purity, " in tranquil 

 clearness of tone and exalted serenity of expression, goes beyond any wood music 

 we ever hear."
