Geothlypis trichas (681). Maryland Yellow-throat. 



Our most abundant summer warbler; first noted on April 20 

 ('91, Resler), it soon becomes common and remains so until 

 October 6 ('95), the last being recorded on October 19 ('92, 

 Resler). The nests of this species, as of all ground buildings 

 birds, are difficult to find, so I have but few items ; extremes 

 are May 24 ('92, Wholey), a nest ready for eggs, and August 13 

 ('93), when young leave a nest. Sets are 1 of 3, and 2 of 4. 

 At Washington "abundant from April 15 ('91, R. Ridgway) 

 to October 21 ('95, Palmer and Matthews)" (Richmond). Not 

 very common on Dan's Mountain, June 514, '95. 



Icteria virens (683). Yellow-breasted Chat. 



Common summer resident, from April 30 ('92, Gray); they

 single birds have been noted until August 30 ('93, Gray). At 

 Washington "from April 29 ('74, Palmer, Hasbrouck and 

 Preble ; '8 8, Hasbrouck) to September" (Richmond). It is given
