1924] Swarth: Birds and Mammals of the Skeena River Region 357

Thirteen specimens collected (nos. 42402-42409, 42411-42415) :
five breeding adults, one adult and four immatures in fresh fall
plumage, and three birds in juvenal plumage.

Passerella iliaca iliaca (Merrem). Eastern Fox Sparrow

On September 14, two fox sparrows were shot from a flock of five
or six flushed from a thicket. The two collected proved to be of the
subspecies tliaca, and from the glimpses I had of the others they all
appeared to be the same. The two specimens collected (nos. 42416,
+2417) are females in completely acquired first winter plumage. One
is typical of the subspecies iliaca in every respect. The second, though
obviously of this same subspecies, is darker colored than the mode,
and not so conspicuously streaked on the back. It is more nearly
uniform reddish above. Near Hazelton, on September 22, a single
fox sparrow (no. 42418) was collected, an immature male. It is closely
similar to the second bird just deseribed, perhaps a trifle darker and
more uniformly reddish. These birds were undoubtedly migrants
from farther north.

The only previous record of the eastern fox sparrow in British
Columbia is of a specimen collected at Sicamous, September 25, 1893
(Swarth, 1920, p. 118).

Passerella iliaca altivagans Riley. Alberta Fox Sparrow

Breeding, not abundantly, at and a little above timber line on
Nine-mile Mountain. In the same general area as the golden-crowned
sparrow and in similar surroundings, though not so much in the
balsam thickets as in tangles of alder and veratrum. Constantly heard
singing but so shy generally as to avoid observation. The young birds
(July 22 to August 13) were flying about; mostly they were in
process of change from juvenal to first winter plumage. In Kispiox
Valley the first migrating fox sparrow of this subspecies appeared on
August 29, and a few more were seen at intervals up to September 7.

Fourteen specimens collected (nos. 42419-42432): on Nine-mile
Mountain, two adults (male and female), six in juvenal plumage and
in the post-juvenal molt; in Kispiox Valley, three males and three
females, all in first winter plumage. These birds, though properly
referred to altivagans (see Riley, 1911, p. 234), are not typical of that
subspecies. In more uniform coloration above and in darker streaking
below they show an unmistakable trend toward the darker coastal
