36 The Ornithology of Chester County 
record; West Chester, Apr. 5-6, 1914, by I. G. 
Roberts (Cass., xviil, 51). 
30. Clangula clangula americana Golden-eye. 
Straggler. I observed a flock of ten at Valley Forge, 
Feb. 12, 1898. 
31. Charitonetta albcola Buffle-head, “butter- 
ball.” Transient visitant. Not common, accord- 
ing to Barnard and Warren; while Pennock states 
that it is frequently met with when migrating. 
32. Erismatura jamaicensis Ruddy Duck. Uncom- 
mon transient. Barnard considered this species rare 
and Warren frequent. Pennock states that he knew 
of several instances of its capture, and Montgomery 
shot an adult female, Mar. 15, 1890, in a marsh 
near Lenape, along the Brandywine. ‘There are 
three later records, all taken at Kennett Square, Apr. 
10, 1906, by Pennock, and Apr. 30 and Oct. 23, 
1915, by Thomas. 
33. Branta canadensis canadensis Canada Goose, 
‘wild goose.” Common transient, seldom coming to 
earth within our limits. On Nov. 25, 1895, a flock 
of 100 or more individuals confused in a fog, came 
down on a hill north of Berwyn, but eventually split 
into three sections and Jater several were shot on the 
west branch of the Brandywine (Wils. Bull., No. 
7,3). On Oct. 16, 1910, a flock of 53 was flushed 
from the Valley Forge dam by a gunner in a boat; 
one bird was disabled by flying against the guy wire 
to a stack, two shot two or three miles up the Val- 
ley creek, and the survivors spent the night on the 
meadows.
