 681. Geothlypis trichas trichas ( Linn . ). Maryland Yellow- 

 throat . 



The Maryland Yellow- throat is an abundant summer 

 resident thruout the state, nesting in all the counties and 

 being apparently just as common on the high spoles of the 

 Alleghanies as in the low swampy land of the Delaware marshes. 



683. Icteria virens virens ( Linn . ) . Yellow-breasted Chat. 



The Yellow-breasted Chat is an abundant inhabitant 

 of busby undergrowths and thickets in the counties lying 

 within the range of the Carolinian fauna. This species is 

 especially common in suitable localities in Chester, Delaware, 

 Montgomery, Lancaster, Washington, and Greene Counties. 

 Lately the Chat has been steadily extending its range to the 

 northward until it has finally intrenched itself as a regular 

 breeding bird in the Alleghanian and is now recorded as a 

 rare breeder from many of the typical Canadian counties. 

 Mr. Stone has recorded it in summer from Harvey's Lake, 

 Luzerne County, fthere the author has observed it in 1910. 

 Mr. Cope found a pair in Potter County in 1910, while the 

 author has located breeding birds recently in Center, Monroe, 

 Pike, and Clarion Counties. Mr. R. B. Simpson took a nest 

 and four eggs in Warren County on June 8, 1911.
