by the Philadelphia and Erie Railroad, on the ridge east of the city. 

 He secured a set of four highly incubated eggs on April 24, 1894, 

 and a second set of three, probably laid by the same pair, on April 

 5, 1895. Both nests were in trees, thirty-five and forty feet from the 

 ground. 



95. Buteo platypterus. Broad-winged Hawk. 



Recorded by our party on but two occasions, but probably a sum- 

 mer resident. An immature male in moulting plumage was shot near 

 the foot of the board-walk on May 26, and one other was seen Sep- 

 tember 21. Mr. Bacon mentions having seen one specimen from this 

 locality. 



96. Archibuteo lagopus sancti-johannis. American Rough-legged 

 Hawk. 



Occurs as a rare winter visitor. One was killed by Mr. Faulkner 

 G. Lynch in the fall of 1900, and on November 4, 1902, Mr. Bacon 

 was so fortunate as to secure a specimen, which is now in the Carnegie 

 Museum. 



\_Aqiiila chrysactos. GoLDEN Eagle. 



A species which may be expected to occur here as a casual visitor.] 



97. Haliaeetus leucocephalus. Bald Eagle. 



This magnificent bird is found here at every season of the year ex- 

 cept winter. The writer met with it first on June 26, 1S99, when a 

 half dozen individuals were noted about the outside beach, and its 

 presence at such a date naturally led to the inference that it was 

 breeding in the immediate vicinity. This inference was strengthened 

 the following year, when the species was repeatedly observed at dates 

 ranging from April 9 until the end of May. Notwithstanding, nothing 

 is more improbable than its nesting on the Peninsula. Such a large 

 nest would easily be visible at a long distance before the trees were 

 in leaf, but none were discovered, and common report was entirely in 

 accord with our observations. It is said to nest, however, at various 

 points on the mainland along the lake bluff (Northeast, Girard, etc.) 

 but the Peninsula is evidently a favorite rendezvous and feeding- 

 ground. Most of the individuals seen are immature birds, although 

 some are apparently adult. It is no uncommon thing for as many as 

 a half dozen to be in sight at once, sailing about overhead, or perched 

 in a commanding position in some tall tree. They frequent all por- 

 tions of the Peninsula, but perhaps are most apt to be met with about
