258 COUES, BIEDS OF NEW ENGLAND. 



No. 1, ^. adult. Salem, Essex Co. J. Eose, Nov. 1854. 



No. 2, $ , adult. " " " " " " " 



No. 298, adult. Hamilton, Essex Co. Mr. Burchstead, Feb. 21, 1867. 



Archibuteo Sancti-Johannis Gray. — Black Hawk. Win- 

 ter visitant. Appears to be nowhere abundant. Not re- 

 corded as breeding. I have seen it in summer in Labra- 

 dor. Very possibly it breeds in the northern districts of 

 Maine. 



The "Black Warrior, i^a?co ^ar?am And.," which has 

 been accredited to Massachusetts, apparently upon Nut- 

 tail's authority {Emm., p. 1; Peab., p. 269; Putn., p. 

 225), should in all probability be consiclered as this spe- 

 cies. Harlani of Audubon, according to G. R. Gray, who 

 has examined the type specimen in the British Museum, 

 is based upon a dark state of plumage of the western B. 

 montanus Nutt. ; which latter itself may not be specifically 

 distinct from horealis Gm. At the same time Mr. Pea- 

 body, following Audubon, does not separate Sancti-Johan- 

 nis from lagopus. Upon these points see Bryant, Pr. 

 B. S. N. H., 1861 ; and Coues, Pr. A. N. S. Phila., 1866, 

 pp. 44, 45. Still the bird may have been an unusually 

 dark-plumaged B. jSwadnsonii, which, as I have just stated 

 above, may possibly occur in New England. 



Circus Hudsonicus Vieill. — Hen Harrier. Marsh Hawk . 

 Blue Hawk. Summer resident, breeding abundantly. 

 Perhaps some winter in more southern localities. 



No. 9, $. Essex Co. Mr. Houghton. 



No. 10, ?. " " " 



Aquila Canadensis Cass. ("Falco fulvus" of some ear- 

 lier American writers.) — Golden Eagle. Hing- tailed 

 Eagle. Very rare winter visitant, occurring usually in 

 isolated instances. Probably does not breed in New Eng- 

 land. Specimens are taken nearly every winter at Wash- 

 ington, D. C. 



No. 7, nearly adult. Essex Co. 



HaliaUus leucocej)halus Savig. — White-headed Eagle. 

 "Bald" Eagle. Common. Resident. Mr. Samuels' state- 

 ment that it does not breed in Mass. is incorrect ; vide All., 

 p. 51. (Mt. Tom, Mass.) I know it to breed as far 

 south, at least, as Washington, D. C.
