44 THE BIRDS OF 



The Catbird and Thrasher are wonder- 

 ful mimics like the Mockingbird. The 

 Brown Thrasher is often called the 

 Brown Thrush, but it is not a Thrush 

 at all. Its colors are somewhat thrush- 

 like, but its voice is not. It may also be 

 easily told by having a bright rufous 

 back, a very long tail and having streaks, 

 not spots like the Thrush, on its breast. 



BLUEBIRD 



The appearance of the Bluebird 

 (Plate 12, p. 97) is a well-known omen 

 of the spring, but the Bluebird really 

 stays with us all winter, though it is not 

 often seen until early spring. Blue- 

 birds generally nest in holes in trees, 

 often those left by Woodpeckers, or they 

 will sometimes nest in birdhouses. 

 Their note is Tru-u-lee, which they fre- 

 quently give while flying through the 

 air. The Bluebird is colored sky-blue
