Compared with young Z. /. nuttalli (which is darker-colored than
leucophrys), young coronata is again darker, more reddish dorsally,
more heavily streaked ventrally, and with less plainly indicated crown
stripes. Tip of bill and most of upper mandible is blackish; base of
bill and most of lower mandible, yellowish. Feet are whitish; eyes
dark.

Zonotrichia albicollis (Gmelin). White-throated Sparrow

An adult male (no. 42303), one of a mated pair, was collected in
Kispiox Valley, June 21. The female was seen repeatedly at the same
place, a partly cleared pasture with scattered thickets of second
growth, and remained there up to the time of our departure, July 15.
When we returned late in August, she had gone. This, I believe, is
the farthest northwest that this species has been found.

Spizella monticola ochracea Brewster. Western Tree Sparrow

One specimen collected (no. 42304), an immature female at Kispiox
Valley, September 13. This was evidently a forerunner of the fall
migration; the species was not breeding in this general region.

Spizella passerina passerina (Bechstein). Eastern Chipping Sparrow

Fairly common in the lowlands about Hazelton when we arrived,
May 26, and evidently settled upon the nesting ground. A female
collected June 8 had laid part of its set; by the middle of July young
out of the nest were seen. The chipping sparrows apparently leave
for the south at an early date. By the middle of August their
numbers had decreased markedly; one in juvenal plumage, collected
August 22, was the last seen. The species was encountered only in
the lowlands.

Hight specimens collected (nos. 42305-42312), two adult males,
five adult females, one juvenal male. To my eye the chipping sparrow
of northern British Columbia is much nearer to the eastern passcrina
in appearance and measurements than to typical arizonae.

Junco hyemalis hyemalis (Linnaeus). Slate-colored Junco

Seen, not abundantly, during the fall migration. The first was
collected August 29; no more appeared until September 13. During
the next two weeks they were encountered almost every day. Ten
specimens collected (nos. 42316-42325), nine males and one female, al!
immatures in first winter plumage.
