Wholey), and another with 1 fresh egg on May 13 ('82), are 

 extreme dates. Young were still in a nest on June 5 ('92) and 

 a family was still holding together on August 13 ('93). Sets 

 are 3 of 2, 3 of 3, 18 of 4, 22 of 5, 1 of 7, and 1 of 10. 

 On Dan's Mountain I only saw 5 or 6 crows from June 5 to 

 14 ('95). 



Corvus ossifragus (490). Fish Crow. 



Resident in tidewater Maryland. Five eggs nearly incu- 

 bated were taken at Gunpowder on May 21 ('93, Fisher), 5 in 

 the same condition on May 26 ('92), and a fresh egg, 5 days 

 later, were collected in Queen Anne County. On June 8 ('94), 

 5 eggs, about to hatch, also 1 fresh egg were, noted at Ocean 

 City. This last nest was only 8 feet from the ground in an 

 alder bush (Alnus maritima), the others were all in the tops of 

 high trees. 



Family ICTERID^E Blackbirds, Orioles, etc. 

 Dolichonyx oryzivorus (494). Bobolink 



Common migrant from April 28 ('95) to May 26 ('95), and 

 from August 9 ('94) to November 8 ('88, Resler). Usually 

 observed in the uplands in spring, they are also numerous there 

 in the fall, while the marshes are alive with them. In April, 

 '95, seven were shot from a flock at Cumberland by Z. Laney. 



Molothrus ater (495). Cowbird. 



Resident ; wintering in tidewater Maryland, they are seldom 

 seen in the uplands until spring (March 12, '92, Gray), when they 

 become numerous, but the majority soon go north, and during 

 summer their presence is chiefly shown by the alien egg in the 

 small bird's nest. In fall, however, flocks of any number up 

 to 300 or 400 are frequently seen between September 16 ('94) 

 and November- 19 ('94). On November 11, '94, I came across 

 an enormous flock of birds, 10,000, or more; they entirely cov- 

 ered a 25-acre field. Careful investigation with a field glass 

 showed about equal numbers of Cowbirds and Red-winged 

 Blackbirds.
