1924] Swarth: Birds and Mammals of the Skeena River Region 335

Accipiter velox (Wilson). Sharp-shinned Hawk

Several seen near Hazelton, migrating, May 27. As single birds
were encountered at intervals during the summer in Kispiox Valley
and on Nine-mile Mountain, it seems likely that a few pairs breed in
the region. The last week in August, with the beginning of the migra-
tion, sharp-shinned hawks became fairly abundant. That is, one or two
birds were seen daily, some days four or five might be encountered.
Three specimens collected: an adult male, May 31 (no. 42040), an
adult female, just beginning the annual molt, July 13 (no. 42042),
and an immature male, August 19 (no. 42041).

Astur atricapillus atricapillus (Wilson). Eastern Goshawk

During the third week in August migrating goshawks appeared,
and from then on, during September, they were abundant. Scarcely
a day passed without at least one being seen, and frequently seven or
eight would be noted within a few hours. The species is usually
solitary but it was not uncommon here to find two together. Mostly
they were young hirds, and as a rule absurdly unsuspicious. Two of
the three goshawks collected during August (nos. 42045, 42046), all
in immature plumage, are evidently of the subspecies atricapillus, and
I believe that nearly all seen at that time were the same. They
appeared to constitute a migratory ‘wave’ from some more northern
region.

Astur atricapillus striatulus Ridgway. Western Goshawk

A female goshawk (no. 42048) of this subspecies collected at
Hazelton, on May 30 is, save for a few scattered feathers on the tibiae,
in immature plumage throughout. A male bird (no. 42044) taken
July 16 is in the midst of the molt from the immature to adult
plumage. An immature male (no. 42046) was collected in Kispiox
Valley, August 29. The last mentioned appeared at the same time
as other migrating hawks. The other two, taken in May and July,
respectively, may indicate the breeding of this subspecies in the region.
They could not be positively recognized as breeding individuals, how-
ever. Remains of flicker and ruffed grouse were found in the stomach
of no. 42044; ruffed grouse in that of no. 42046.
