Wyoming Birds. 79 



TU'RDIDAE (Thrushes, Robins, Bluebirds, etc.). 



Many of the Thrushes live in deep woods, but the Bluebirds 

 and Robins nest in the more open country near human habitations. 



The Bluebirds and Robins feed upon cutworms and other cater- 

 pillars, butterflies, moths, grasshoppers, crickets, bugs, beetles, etc. 

 The Robin is fond of cultivated fruit. Both birds eat wild fruit to 

 some extent. The young birds are fed almost entirely upon insects 

 and their larvae, principally caterpillars and grasshoppers. The 

 Thrushes' food does not differ materially from that of the Robin 

 and Bluebird, except that the fruit taken is wild fruit. 



This entire family of birds is beneficial, not excepting the Robin, 

 about which some doubt has been expressed.
