1870.] REEKS — ON THE BIRDS OF NEWFOUNDLAND. 41 



compressed laterally, but not so much so horizontally as that of 

 F. columbarius. The tibiae in my adult male specimens of the 

 American bird (F. columbarius) are darker ferruginous, with 

 narrower longitudinal lines, than in my English specimens of 

 F. ^salon ; but this distinction may not be constant. I had 

 almost forgotten to state that the inner webs of the tail-feathers of 

 F. columbarius are white, except where crossed by the black bars 

 — in this respect differing from F. ^salon, which has scarcely 

 any variation in either web, both being bluish ash. 



Greenland Falcon (F. candicans, Gmeliii). — This is the *' white 

 hawk,'' of the Newfoundland settlers. It is pretty regular in its 

 periodical migrations, especially in the fall of the year. I was not 

 successful in obtaining specimens ; I do not think it breeds in any 

 part of Newfoundland. 



American Sparrov) Hawh (F. sparverius, Linn.^ — A summer 

 migrant to Newfoundland, but not so common as F. columbarius. 

 The following species of Falco may reasonably be expected to 

 occur (and probably do so) in Newfoundland occasionally : — The 

 duck hawk (F. Anaturti) and the Iceland falcon {F. islandicus). 

 American Goshawk (Astur atricapillus, Wilson). — 1 have only 

 the authority of the settlers foi* including the "goshawk'' in my 

 list of Newfoundland birds. I have no reason to doubt their 

 accuracy, as the more enlightened on Ornithology recognised the 

 plate of this species in Faun. Bor. Am., where the scientific name 

 only is given. 



Cooper's Hawh (Accipiter Cooperi, Bonap.) — A summer 

 migrant; not unjcommon. 



SharpsMnned HawJc (A. fuscus, Gmelin). — A summer migrant, 

 and about equally common with the preceding. I have not seen 

 the young of this species, but the adult very closely resembles our 

 sparrow hawk (H. Nisus) both in flight and plumage. I have 

 not, however, compared specimens, but hope to do so before the 

 conclusion of these " Notes," and give the result. 



Redtailed Hawh (Buteo borealis, Gmelin). — A summer 

 migrant, but not so common as on the mainland. I only examined 

 one specimen, shot in Newfoundland. 



The following species of Buteo probably occur on the island : 

 The redshouldered hawk (2?. Uneatus, Gmel.) and the broadwinged 

 hawk (^B. Pennsijlvanicus, Wilson). I think I have seen the 

 latter on wing, but obtained no specimen. 



Blach Hawk (Archibuteo Sancti-Johannis, Gmelin') . — Common ;
