BIRDS OF PENNSYLVANIA .

“ I have never as yet found this species in Beaver county, either as a summer resi¬ 
dent, or as a transient visitant, although the other species of the genus native to the 
eastern United States are abundant in their season.” 
Note.— Unless otherwise specified, the remarksabove given refer to Beavercounty. 
“ The records from Butler and Armstrong counties were obtained during a stay there 
extending from May 15 to June 14, 1889, and are necessarily not so full as could be 
wished. The locality in question is near the postoflice of Leasuresville, Butler 
county, about six miles directly north of the town of Freeport, in Armstrong county. 
Buffalo creek is the principal stream, and it is in the narrow valleys which are rarely 
a hundred feet wide, of the brooks emptying into this, that bird-life is most abund¬ 
ant and varied. * * * The dissimilarity between the avifauna of Beaver county 
on the one hand, and that of Butler and Armstrong counties on the other, may be 
still further exemplified by the following table, in which the status of certain species 
for the two sections respectively are given in parallel columns 
Beaver County.

Additional Notes from Reaver County. 
[These notes have been compiled from an unpublished “ List of the Birds of 
Beaver County, Pennsylvania,” recently prepared and kindly forwarded to the 
author by Mr. H. H. Wickham, of Beaver City. Numbers following common names 
refer to pages in this volume where additional information relating to the bird will 
be found. ] 
Larus argantatus smithsonianus. Herring Gull (14). Not an uncommon mi¬ 
grant. It is often observed in company with Terns on the Ohio river. 
Phalacrocorax dilophus. Cormorant (28, 29;. Rare migrant. One seen in the 
spring of 1889. Mr. W. E. Clyde Todd obtained a specimen November 16, 1889. 
Another individual of this species was observed by Mr. Wickham, April 16, 1890. 
Anas hoschas. Mallard (35, 86). Occurs singly or in pairs during migrations. Itis 
seldom, if ever, seen in flocks around here, but often mingles with the smaller ducks, 
and accompanies them on their journeys. 
Aythya ajfinis. Lesser Scaup Duck (44). This is one of our most common mi¬ 
grants, and is one of the first water fowl to arrive in the spring. During stormy 
weather many of these ducks are shot on small ponds back of town ( Beaver). The 
food of this duck seems to consist of sand and small pieces of shells. Its flesh is not 
regarded with favor by epicures. 
Erismatura rubida. Ruddy Duck (48, 49). Common migrant, but not as abund¬ 
ant as affinis. The flesh of the Ruddy Duck is highly esteemed as an article of food. 
Breeds near Kittanning. Armstrong county.—B. II. WARREN.
