100), given by Peab., p. 268, and Linsley, p. 252, is now 

 well known to be the young of this species. Nuttali him- 

 self, in the second edition of his Manual, gives it as a 

 synonym of the B. " hyemalis" (= Uneatus, juv.). 



No. 3, $, adult. Winter plumage: Essex Co. 

 No. 678 $, adult. Danvers, Essex Co. J. H. Sears, Apr. 13, 18G8. 

 (Shot on the nest. Eggs.) 



Buteo Pennsylvanicus Bon. Broad- winged Buzzard. 

 Generally distributed. Common ; being very abundant 

 in some localities (e. g. Umbagog Lakes, Verr., p. 6). 

 Resident ; with much the same qualification as given 

 under head of previous species. 



In addition to the preceding Buteones the B. Bairdii 

 Hoy, originally described from Wisconsin* which has 

 been found in Canada West by Mr. T. Mcll wraith, may 

 very possibly occur in North-western New England. Buteo 

 Bairdii is one of several usually recognized species which 

 Dr. H. Bryant (Pr. B. S. N. H., 1861) is inclined to coal- 

 esce as a single species under the name of B. Harlani 

 And., or rather B. Swainsonii Bon., since it is probable 

 that Audubon's name was based upon quite a different 

 species. (Vide infra, under head of A.rchibuteo Sancti- 

 Johannis.) But whether Bairdii be permanently distinct 

 or not, does not affect the question of its introduction into 

 the New England Fauna. 



Mr. Mcllwraith gives Buteo ebegans Cassin, as a bird of 

 Canada West. "I have a fine specimen in adult plumage, 

 which was shot at Baptiste Creek a few years since." So 

 far as we are at present acquainted with the range of this 

 species it is quite impossible for me to think that it should 

 occur there ; and I am inclined to believe, from the nature 

 of Mr. M.'s remarks, that the specimen in question is 

 merely a somewhat unusually dark-colored example of 

 Uneatus. 



Archibuteo lagopus Gray. Rough-legged Hawk. 

 Winter visitant. Not ordinarily abundant. I can learn 

 of no authentic instances of its breeding, although it 

 probably does so in more northern sections. " F. /Sancfi- 

 Johannis" of Linsley's list.
