Capt. Blakiston on the Birds of the 
while Mr. Murray has recorded F. candicans { Gmelin) from the 
same locality. On the Saskatchawan this bird, or rather one of 
these birds, is rare, for I have only three or four recorded instances 
of having seen any individuals of the Falcon family during winter. 
It is known to the Indians and half-breeds of the interior as 
“the Hawk that winters. 3 * Some specimens which have lately 
come from Hudson 3 s Bay differ considerably, the largest measur¬ 
ing 16J inches in the wing. Mr. J. H. Gurney has decided that 
they are of two species, F. islandicus and.F. grcenlandicus . 
Falco sparverius. 
The American Sparrow-Hawk is identified as an inhabitant of 
the interior by specimens from the forks of the Saskatchawan 
recorded in the ( Fauna Boreali-Americana, 3 also one in the 
museum of the Smithsonian Institution from between Hudson 3 s 
Bay and Lake Winipeg, and from the Mackenzie by Mr. Bernard 
Boss. I found it throughout the prairie country, where, in the 
spring, it comes in the van of the migratory birds, and whence it 
continues its journey as far as the Arctic Circle. I observed an 
individual at Bed Biver Settlement on the 22nd of April, in 
1859, the day previous to the arrival of the first Goose, while 
the whole country was yet covered with snow, and the decided 
spring thaw had not commenced. The year previous, I saw 
what I took for the Sparrow-Hawk on the 15th of March, at 
Fort Carlton, while Sir John Bichardson observed it, the spring 
which he spent there, on the 13th. 
3. Astur atricapillus. 
The Goshawk is found to range throughout the interior from 
Hudson 3 s Bay to the Bocky Mountains and Mackenzie Biver. 
My specimens ( f Ibis, 3 vol. iii. p. 316), collected as far west as the 
Saskatchawan, do not differ from others from the most eastern 
part of the continent, Nova Scotia. 
4. Accipiter cooperi. Killed at Fort Carlton. (See f Ibis, 3 
vol. iii. p. 317.) 
As Accipiter mexicanus has been found on the Upper Missouri, 
I would draw attention to it as likely to be an inhabitant of the 
Saskatchawan Plains, between which and the prairie bordering 
the former river there is no natural line of demarcation.
