it had been feeding on a Snow-bird. On April 30, ’93, in 
Dulaney’s Valley two birds swished close past me making for 
a small scrubby thorn bush, round which they went several 
times; finally one darted into its centre, the other kept round 
once more and lit ontop. I then saw that they were a Catbird 
and a Pigeon Hawk, the hawk seeing me flew, but the Catbird 
remained apparently thoroughly exhausted. On October 30, 
792, I surprised one feeding on a dove. A not uncommon 
migrant at Washington (Richmond). “Mr. F. L. Washburn, 
of Johns Hopkins University, has reported to the Agricultural 
Department that he observed several pairs, apparently breeding 
at Harper’s Ferry, April 12, ’87” (Birds Vas., 62). 
Falco sparverius (360). American Sparrow Hawk. 
Resident, common, but most numerous during the migrations 
of small bird. Hence,on March 18 (’93, Wholey and Gray) 
about 75 were seen in Dulaney’s Valley. During summer they 
are not often seen except in the locality of the nest. Dates for 
eggs range from April 17 (95, Henninghouse) to May 28 (’93), 
and a second set was taken June 24 (94). On August 4 (’95) 
flying young were still being fed by the parents. Sets are 9 of 
4 and 6 of 5. 
Pandion haliaétus carolinensis (364). American Osprey. 
Common summer resident on all our larger waters, extremely 
numerous on the arms of the Chesapeake. On March 11 (93, 
Blogg) five were seen at Fulton Avenue. On the Eastern 
Shore it is maintained that they always arrive on St. Patrick’s 
Day, March 17. Dr. Sharp’s attention was called to this, and he 
reported that the first bird arrived at Rock Hall on March 14, 
795. Late in September most have gone south, but they have 
been noted later, the last on November 8 (’92, Blogg). 
On April 3 (93) they were patching up old nests at the 
mouth of Gunpowder, and on April 24 (94, Tylor) sets of 
fresh eggs were collected in Talbot County, where on August
