stated that two broods of young were found in 1886. 
A pair raised a brood at Strode’s mill dam, near 
West Chester, a few years ago, and S. B. Ladd had 
a set of eggs collected for him on the West branch 
of the Brandywine some years since (Sharples MS.). 
Wilson writes that pairs are to be found along the 
unfrequented portions of the Octoraro and occasion- 
ally along Buck and Doe run. He mounted a speci- 
men Mar. 30, 1898, shot at Glenville dam, W. 
Fallowfield Twp. In the vicinity of Berwyn, a 
pair nested along the Valley creek and three of the 
young were bagged by a local hunter, Nov. 3, 1891; 
another pair frequented a dam at the head of the 
Darby creek during the summers of 1909-1910, 
doubtless nesting in the willows, since the young 
were seen, and some of the birds shot in the fall. 
The most recent capture is by C. A. Thomas, Ken- 
nett Square, Nov. 14, 1914 (Cass., xvill, 51). 
27. Marila americana Redhead. Straggler. Some 
thirty years ago, Warren came upon a flock of 
thirteen near Deborah’s rock, along the Brandywine, 
and secured two (Bds. Pa., 1890, 42). 
28. Marila valisineria Canvas-back. Straggler. 
Stray individuals, probably lost from flocks migrat- 
ing in October and November, have been shot by 
hunters on the Octoraro, Buck run and the west 
branch of the Brandywine (Wilson MS.). 
29. Marila affinis Lesser Scaup, “scaup,” “little 
blackhead.” Transient. Barnard and Warren give 
it as rare, while Pennock states that it is rather 
common on small streams and ponds in small flocks 
in spring and fall. We have but one recent definite
