which are in damp woodlands and shaded dells, the Wood 

 Thrush, while common, is not, perhaps, a well known bird. Its 

 rich and melodious song, however, once heard can never be for- 

 gotten, and it is by its song that the bird is best known, at least 

 in rural districts. It is said that the mockingbird has never been 

 able to imitate the beautiful harmony and liquid melody of the 

 Wood Thrush's song. 



The range of this Thrush covers the United States, east of 

 the Great Plains, and the eastern and southern portions of the 

 British Possessions. It breeds from Georgia and southern Mis- 

 souri northward and winters from Florida and Texas southward.

Wilson's Thrush is a not uncommon migrant, arriving, in the 

 spring, from the last of April to the last of May and returning 

 in the fall from the middle to the last of August. Mr. Robert 

 Kennicott records* this species as "common throughout the 

 state," and also states that it is known to nest in Cook County, 

 Illinois. Mr. E. W. Nelson says : ."Rather rare summer resi- 

 dent. Arrives in small numbers the second week of May and 

 departs the first of September." I have no authentic records of 

 the eggs of this species having been taken within our area during 

 recent years. Mr. J. Grafton Parker thinks that it may be a 

 rare summer resident here. 



The range of Wilson's Thrush extends through the United 

 States east of the Great Plains and from Manitoba, Ontario and 

 Newfoundland southward. It breeds from New Jersey and 

 northern Indiana northward and in the AUgehany Mountains 

 south to North Carolina. It winters to some extent in the south- 

 ern states, but chiefly through Central America to Brazil.
