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

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

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

 synonym of the B. '^ hyemalis'' (= lineatus, juv.).

 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, Yerr., 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. Mcllwraith, 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 

 Aud., or rather B. 8wainsonii Bon., since it is probable 

 that Audubon's name was based upon quite a diiferent 

 species. (Vide infra, under head of Archibuteo Sancti- 

 Johannis.) But whether Bairdii be permanently distinct 

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

 the New England Fauna. 



Mr. Mcllwraith gives Buteo elegans 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 

 lineatus. 



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. Sancti- 

 Johannis" of Linsley's list.
