No. I Birds of Princeton. 



59(33 0- Marsh Hawk; Harrier. Circus hudsonius 



A common migrant, not infrequent winter and occasional summer 

 resident. An adult male was shot at Clarke's Island January 4, 1 898, and 

 it is not unusual to see several in the brown phase of plumage each 

 winter. Prof. Phillips has in his possession a nest and set of eggs 

 taken on Phillips' Meadows. Mr. Scott procured two adult males in 

 full plumage April 22, 1875, ^'^^ i^i the University Collection Nos. 

 538 and 539. 



60 (332). Sharp-shinned Hawk. Accipiter velox 



{Wils.). 



A not uncommon migrant, winter resident, and a rather infrequent 

 summer resident, breeding every year in the heavy woods on Sorrel 

 Mountain. On May 16, 1898, I found a nest high up in a pin oak near 

 Blawenburg. The tree was too difficult to climb, but from the actions 

 of the parent birds 1 judged that the nest contained young. 



61 (333)- Cooper's Hawk. Accipiter cooperii (j^^;?^/.). 



Similar to A. velox but breeding more frequently. Mr. Robert 

 H. Southard found a nest near Lawrenceville, May 2, 1896, containing 

 three eggs. Others have been found by local gunners. 



62 (334). American Goshawk. Accipiter atricapil- 



liis {Wils.). 



An irregular and rather infrequent winter visitor. During the past 

 four years I have observed this species but twice, and so far as known 

 only two specimens have been taken, one, an immature female, was shot 

 November 20, 1897, on Mount Lucas, and is now in the University 

 Collection, No. 6940 ; the other, an adult bird, is in the possession of 

 Mr. C. F. Silvester of the Biological Laboratory. Mr. Scott secured 

 two during January 1879. (See Bull. Nutt. Om. Club, Vol. IV, No. 2, 

 p. 85, April, 1879.) 



63 (337)- Red-tailed Hawk. Buteo borealis GmeL). 



At present this species is only a tolerably common winter and rare 

 summer resident, and seems to be decreasing in numbers. A nest was 

 found, April 17, 1898, on Sorrel Mountain, where two or three pairs
