According to luy experience, the Chestnut-sided Warbler is a very " ' 

 common species of the Eastern United States, passing through in great ■^^'' 

 numbers during the migrations, where it is found in orchards and open 

 woods in company with severa^ other species. It is rather southerly in 

 distribution, apparently not passing much, if any, beyond the- United . 

 States, in the northern parts of which it breeds. It retires far south in 

 winter. The numerous nests in the Smithsonian collection agree in 

 being placed in an upright crotch, generally of several stems, and are 

 all more or less lengthened perpendicularly to fit such situations, with a 

 rather naiTOw but deep cavity. The twigs preserved with the nests are 

 all small, and in one case the nest was only a yard from the ground. 

 The exterior is a rather loosely woven mass of weedy, downy, and fibrous 

 substances; the iuterior is more closely woven of fine gras.ses, with a 

 tolerably firm and even brim. Sometimes there is horse hair lining, 

 sometimes not. None of the nests contain more than four eggs ; sev- 

 eral only three; one is occupied alone by a Cow-bird's. The shell is 

 white ; the markings are chiefly confined to the larger end, only rarely 

 a few dots being sprinkled over the whole surface, and tbey form, or 

 tend to form, in many cases, a wreath about the large end. The wreath 

 is sometimes close and heavy, consisting of confluent blotches, in other 

 instances is a circle of separate fine dots. The markings are of all 

 shades, from light reddish to various darker browns, mixed with neutral 

 tints. The size is about 0.08 by 0.50.
