 "A common summer resident at Washington, from April 20 

 to the middle of September. Wm. Palmer found a nest with 

 3 small young on June 1, '94" (Richmond). On May 27 ('93, 

 Blogg) a nest held 3 half -incubated eggs; on June 15 ('93, 

 Fisher) one contained young birds, and on June 19 ('92, Wholey) 

 one had 4 eggs ready to hatch. 



Vireo solitarius (629). Blue-headed Vireo. 



A regular migrant, not common. Noted from April 19 ('93, 

 Resler and Wholey) to May 11 ('93, Pleasants), and from Sep- 

 tember 26 ('94, Resler) to October 22 ('92, Gray). During 

 spring single birds are usually seen ; in fall, small parties of 4 

 or 5. At Washington "not uncommon in migrations, April 13 

 ('88, Hasbrouck) to May 10 ('85) and October 8 ('88) to October

 climbing roses, and were very unsuspicious" (Small). 



Vireo noveboracensis (631). White-eyed Vireo. 



Common summer resident from April 22 ('91, Resler) to 

 September 23 ('94). At Washington "from April 12 ('90) to

27 ('95, Fisher), 2 fresh eggs, to August 6 ('93), 2 birds about 

 two-thirds grown. Sets are 1 of 2, 3 of 3 and 1 of 4. 



While the nest is usually placed near water, or in a swampy 

 place, on July 4, '94, I found a nest containing young nearly 

 ready to fly, on top of a high, dry hill, fully J of a mile from 

 the nearest spring.
