PERCHERS.

The Catbird of the Northern States is smaller than 

 the Robin, and of a dark color, and in spring and the 

 early part of summer its song is very mellow and sweet. 

 Like its relative, it easily imitates the notes of other 

 birds, and may be properly called the Mocking" Bird of 

 the North. President Hill, of Harvard College, states 

 that, having whistled a strain of Yankee Doodle two 

 or three times in the presence of this bird, it imitated 

 him perfectly. In the latter part of summer its notes 

 are harsh and disagreeable, sounding like a cat's yawl. 



Wrens are small Birds about the size of the War- 

 blers. The Carolina Wren is one of the largest. It is 

 reddish-brown. The House Wren 

 delights in being near the habita- 

 tions of man, and often makes 

 its nest in a hole in the timbers 

 or walls. The Winter Wren is 

 one of the smallest, and of a 

 brownish color. It is very ac- 

 tive, and may be seen in twenty 

 attitudes in a minute. Fig. 129. —Winter Wren. 



Creepers, Nuthatches, and Chickadees. 



Creepers and Nuthatches are very small Birds, which 

 may be seen in North America at all seasons of the 

 year, running along the trunks and branches of trees, 

 and looking, at a little distance, much like little Wood- 

 peckers. The American Creeper is light brown, with 

 lighter streaks. The White-bellied Nuthatch is blue, 

 with the under parts white, and the top of the head and 

 neck black. The Red-bellied Nuthatch is a smaller spe- 

 cies, and has the under parts Ted. Both kinds attach
