Hab. — Eastern United States and Southern ( 'anada, west to tlie Plains, 

 breeding .southward to Central Illinois and in the Appalachian Highlands, 

 ]jrobal)ly to Northern (Jeorgia. Visits the Bahamas and Central America in 

 winter. 



Xest, in tlic fork of a busii or sapling, three to eight feet from the ground, 

 composed of l)ark strips and gi-ass, and lined with plant doW'U and hair. 



Kggs, four or five creamy-white with re<ldish-bi-own marking. 



The Chestnut-sided is a common .summei' resident, l)reeding in 

 suitable places near the city and throughout the country, and raising 

 two brood.s in the .sea.son. It is very partial to briar patches, but 

 -sometimes goes gleaning for insects among the trees, when the 

 blending of its varied plumage with the fresh spring foliage produces 

 a very pleasing effect. It arrives fiom the south about the 10th of 

 May, and departs early in September. 



Although it seems quite at home in .Southern (Ontario, many 

 individuals must take a wider range, for Dr. Coues reports it as 

 a common summer resident in the woodlands near Pembina, and 

 Kennic(ftt found it at the Lake of the \Vof)ds on the "ioth of Ma}'. 

 The song, when heard in its haunts in the early spring, is pleasing, 

 and delivered with much spirit. Any oi these birds whose notes T 

 have once r)r twice heard 1 readily recognize again, and trust to the 

 f'fd' more than to the fj/r to tell wiiat biids are about me in the bush.
