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.

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, 
795, 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 (794). On November 11, 794, 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-wingce! 
Blackbirds.
