16J: EEPOET OF NEW JERSEY STATE MUSEUM. 



343 Buteo platypterus (Vieillot). 

 Broad-winged Hawk. 



Adults. — Length, 14-18. Wing, 10-11.50. Above, dark brown, edged with 

 buff and gray ; lower parts, white, heavily barred with buffy-brown ; tail, dark 

 brown, with two bars and a terminal band of gray. 



Young in first year. — Similar, but under parts white, somewhat tinged with 

 buff, and streaked with brown ; tail, grayish, with indistinct dusky bars and a 

 light tip. Easily recognized from the Red-tail and Red-shouldered Hawk by 

 its smaller size and the fact that only three instead of four outer primaries are 

 notched on the inner web. 



Nest in trees ; eggs, two to four, dirty white, blotched with rusty brown or 

 ochraceous, 1.90 x 1.55. 



A resident species in the southern part of the State and summer 

 resident in the north, but nowhere common in the winter and not 

 as abundant as the Eed-shouldered Hawk in summer. 



347a Archibuteo lagopus sanctijohannis (Gmelin). 

 Eough-legged Hawk. 



Adults. — Length, 20-23. Wing, 16-18. Above, dark brown, edged with white 

 or buff ; tail, white or buff at the base, and with several light bars ; under 

 parts, buffy-white, spotted with black, spots often confluent on the belly ; some- 

 times the entire plumage is black except the bars on the wings and tail. 



Young in first year. — Browner, without bands on the tail. 



Distinguished in all plumages from all our other hawks by having the tarsus 

 feathered all the way to the toes. 



Winter visitant from the north, but usually not common and not 

 uniformally distributed, apparently much more plentiful on the Dela- 

 ware meadows than elsewhere. Some entirely black individuals 

 were formerly shot every year, but such birds are now rarely seen. 

 The Rough-leg seems to be rare on the coast, but a specimen was shot 

 at West Creek, Ocean county, March 8th, 1909. 



Meadow mice constitute almost the entire food of this Hawk while 

 it is with us. 



349 Aquila chrysaetos (Linnaeus). 



Golden Eagle. 



Adults. — Length, male, 30-35 ; female, 35-40. Wing, male, 23-24 ; female, 

 25-27. Entire plumage, brown, except the back of the head and tarsi, which 

 are more or lesss buff or tawny, and the tail, which is somewhat streaked with 

 srar.
