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 Brands^wine. There 'are 

 three later records, all taken at Kennett Square, Apr.

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 later 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.
