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 Hierofalco of northern 

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

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

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

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

 ^ Falco columbarius 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 And., 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 Hypotriorchis, the 

 European F. cesalon. Examine in this connection Coues, 

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

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

 quotes Nuttall as authority.

-^ Falco sparverius Linn. — Sparrow Hawk. Resident. 



Generally distributed and common; breeds throughout 



New England. 



No. 16, ,y, adult. Essex Co. George Goldthwait. 



Falco aueantius Gm. — I find an excellent example 

 of this species in the collection. 



No. 43, Brazil. 



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.)
