three exposed, and one concealed by the upper tail-coverts. In 

 F. iEsalon the female only has the tail-bars distinct, and they are six 

 in number — five exposed and one concealed. The bars on the tail 

 of the adult male F. ^Esalon, although six in number, are only par- 

 tially defined, and consequently very indistinct. The bill of F. ^salon 

 is slightly more compressed laterally, but not so much so horizontally 

 as that of F. colunibarius. 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. .Esalon ; but this distinction may not be constant. I had almost 

 forgotten to state that the inner webs of the tail-feathers of F. colum- 

 barius are white, except where crossed by the black bars — in this 

 respect differing from F. iEsalon, which has scarcely any variation in 

 either web, both being bluish ash. 



Greeffland Falcon (F. candicans, Gmelin). — 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 Sparrow Hawk (¥. sparverius, Linn.) — A summer mi- 

 grant 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. Anatum) and the Iceland falcon (F. islandicus). 



American Goshaivk (Astur atricapillus, Wilson). — I have only the 

 authority of the settlers for 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 ^(7^^>^• (Accipiter Cooperi, Bonap.) — A summer migrant; 

 not uncommon. 



Sharpshinned Hawk (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 Hawk (Buteo borealis, Gmelin). — A summer migrant, but 

 not so common as on the mainland. I only examined one specimen, 

 shot in Newfoundland.
