 "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

 the spring migrations ; they had a decided partiality for some 

 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 

 October 12 ('90)" (Richmond). Nesting notes range from May 



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 | of a mile from 

 the nearest spring.
