two eggs; one bird was hatched on April 22, and another the 
next day (Henry Hulce, Forest and Stream, xxvi, 327 and xxx, 
289). 
Falco peregrinus anatum (356). Duck Hawk. 
“Universally, but irregularly distributed in North America, 
scarcely to be considered common anywhere, breeds as far south 
as Virginia at least, usually in mountainous regions” (Key, 
536). ‘Nests sparingly from 35° north” (Bendire, 292). On 
March 5 (’87, Fisher), one was seen at Grace’s Quarter, but it 
kept out of range. On December 10, 94, one was brought 
alive to Baltimore by a countryman, and lived for about four 
months in the window of No. 208 E. Baltimore street. 
“Mr. W. T. Roberts got a female on November 16, ’79, at 
Potomac Landing, near Washington” (Richmond). “Mr. Jouy. 
states that the Duck Hawk has been known to breed at Harper’s 
Ferry” (A. C., 87). In reference to this, Mr. W. H. Fisher 
had a conversation with a resident of Harper’s Ferry on October 
10, 793. He was not acquainted with the “Duck Hawk,” but 
stated that the “Rock Hawk” nested on the face of the Mary- 
land Heights, and that the site of the nest could be easily 
located by the “ white-wash ” after the young were hatched. 
This species is reported as regularly breeding along the Sus- 
quehanna in Lancaster and York Counties, Pa. In the latter 
county a set of four slightly incubated eggs was taken on April 
7, 80, by Mr. Geo. Miller (Birds Pa., 137). 
Falco columbarius (357). Pigeon Hawk. 
“Whole of North America, breeding chiefly north of the 
United States” (Manual, 250). “Doubtless breeds in the 
mountainous portions of some of the Southern States” (Ben- 
dire, 299). 
I have but few notes on this powerful little hawk. On 
April 19, ’92, one was shot at Washington, that had been feed- 
ing on a Sparrow-hawk (Fisher’s Hawks and Owls, 118). On 
April 26, ’93, one was shot near Bay View by A. Wolle,
