 pensylvanica. 



Range. — United States, east of the Plains, breed- 

 ing in the Middle States and Illinois, north to Man- 

 itoba and New Brunswick. Winters south of our 

 border. 



The adults of this handsome spe- 

 cies may readily be known by the 

 white underparts and the broad 

 chestnut stripe on the flanks; the 

 crown is yellow. They frequent low 

 brush in open woods or on hillsides 

 and pastures, nesting at low ele- 

 vations, usually below three feet from the ground, 

 and often concealing their nests beneath the 

 leaves in the tops of low small bushes. The nests 

 are made of grasses, weed stems and some fibres, 

 but they do not have as wooly an appearance as 

 those of the Yellow Warblers which nest in the 

 same localities and similar locations. Their eggs 

 are white or creamy white (never greenish white), 

 specked with brown and gray. Size .65 x .50. 

 Data. — Worcester, Mass., June 6, 1890. Nest in 

 the top of a huckleberry bush, 2 feet from the 

 ground; made of grasses and plant fibres. Bird 

 did not leave nest until touched with the hand.
