CHESTNUT-SIDED WARBLER. 



659. Dendroica pensylvanica. 5 inches. 

 Yellow crown, black line through eye and on side of 

 throat, and broad chestnut stripe on sides; female, 

 paler and with less chestnut; young greenish yellow 

 above and with no chestnut. 



Nearly every swamp or bush-covered pasture within 

 their range shelters one or more pairs of these Warb- 

 lers. While they sometimes feed in the tree tops, they 

 are birds of the lower foliage and are usually seen in 

 low bushes. 



Song. Similar to that of the Yellow Warbler but 

 more choppy. 



Nest. In low bushes or weeds, and often in sweet 

 fern or briars; similar to that of the Yellow Warbler 

 but coarser, being made more with grasses than with 

 fibres, situated in upright forks or attached to several 

 weed stalks; egg white, specked around the large end 

 with reddish brown (.68 x .50). 



Range. Eastern N. A., breeding from New Jersey 

 and Ohio north to Manitoba and New Brunswick; win- 

 ters south of U. S.
