68 (352). Bald Eagle. Haliaeetus leucocephalus 



{Linn.'). 



Occasionally a straggler appears from the coast, but this species is 

 here an infrequent visitor. A specimen was shot at Cedar Grove, May 

 6, 1885, which is now in Prof. Phillips' collection, No. 401. 



69 (356). Duck Hawk. Falco peregrinus anatum 



{Bonap.'). 



The Duck Hawk occurs here only as a rare migrant. I have seen 

 it twice during October, but never in spring. Two specimens are in 

 the University Collection, No. 569, an immature female, taken October 

 5, 1875, ^I'^d No. 6332, an adult female, taken October 6, 1881. 



7^ (357)- Pigeon Hawk. Falco columbarius Linn. 



A not uncommon migrant, especially in autumn, and rare winter 

 resident, occurring during March and April, and from September until 

 cold weather. I secured a specimen on January i, igoi. 



71 (360). American Sparrow Hawk. Falco spar- 



verius Linn. 



A common resident species and the most abundant of all our 

 hawks. By April i, the birds have selected a suitable cavity, generally 

 a deserted flicker's hole, and by May i, the five eggs are laid, the same 

 cavity being used for many seasons. For six consecutive years a pair 

 have nested in a pin oak stump on Stony Brook, near the Washington 

 Street Bridge ; and last spring (1900) a telegraph pole on the Junction 

 road was cut down, in which a pair had reared their young for several 

 years. The favorite nesting sites in this locality, however, are the 

 large dead trees along the Millstone. During the colder months the 

 Sparrow Hawks frequent the open fields and meadows, especially those 

 in which hay has been stacked. 



72 (364). American Osprey ; Fish Hawk. Pandion 



haliaetus carolinensis [GnieL). 



A not uncommon migrant along the water courses. There are no 

 records of their nesting here, but stragglers begin to arrive from their 

 breeding places early in July and continue until the middle of October. 

 In spring they are seen from March 20 to May i.
