 and 26, and January 18, 19, 20 and 21." 



Contopus borealis (459). Olive-sided Flycatcher. 



Rare migrant. "The claim of this species to a place in our 

 list (of the District of Columbia) rests upon Mr. Ridgway's obser- 

 vation near Fall's Church, Va., where several birds were noticed in 

 September, '81. Further west in Virginia, the species cannot be 

 considered very rare, individuals having been observed for 3 or 4 

 successive summers by one of the authors, and Dr. A. K. Fisher 

 has taken a specimen in the Bull Run mountains" (H. M. Smith 

 and Wm. Palmer, Auk, v, 148). 



"Judge Libhart states that this species (probably 15 or 20 

 years ago) was found as a breeder in Lancaster County, where, 

 however, in recent years it has been observed by Dr. Treichler 

 only as a rare spring and fall migrant" (Birds Pa., 194).
