COUES, BIRDS OF NEW ENGLAND. 7 



falcon. Mr. John Cassin, in reply to some Inquiries of 

 mine upon this subject, kindly furnishes me with the fol- 

 lowing : " I regard the species of llierofalco of northern 

 America as the F. candicans of authors (e. g. Bon. 

 Consp. Av., etc.). — F. cinereus Gmelin ; F. Grmnlandicus 

 Daudin ; F. Lahradora Aud. (name on plate) ; F. sacer 

 Forster ; which latter is the name which has priority." 



Falco columharius Gm. — Pigeon Hawk. Generally 

 distributed. Not abundant. Resident. Breeds at least 

 as far south as Massachusetts. — (Sam., p. 3.) It ranges 

 through the Middle and into the Southern States in winter. 



The "Little Corporal" F. temerarius Aud., Nutt., of 



Peab. (p. 261 ; Lins., p. 251), is based upon this species 



in one of its protean plumages, when its upper parts are 



light slate-blue, as occurs chiefly in very adult birds. 



There is possibly a second species of Hyj}Otriorchis, the 



European F. msalon. Examine in this connection Ooues, 



Pr. A. N. S., Phila., 1866, p. 42 ; and for the occurrence 



of supposed msalon in Mass., see Peah. (p. 270), who 



quotes Nuttall as authority.

Falco aurantius Gm. — I find an excellent example

Astur atricapillus Bon. — Goshawk. "Partridge" Hawk. 

 Generally distributed. Chiefly winter visitant, and rather 

 uncommon in southern portions ; common, and breeds, in 

 Maine. I have also found it breeding in Labrador. In- 

 dividuals in the adult blue plumage are rarely seen in 

 Mass. (Norway, Me., "common, breeds," Verr\, p. 5.)
