Selasphorus rufus (Gmelin). Rufous Hummingbird

Abundant about Hazelton when we arrived, May 25. Frequenting
gardens in the town and generally distributed through the lowlands.
On Nine-mile Mountain a few hummingbirds were seen, perhaps ten
or twelve all told during our stay (July 21-August 14) ; apparently
all were young birds, wanderers from the valleys below. By the time
we descended from the mountain, there were very few rufous hum-
mingbirds left in the lowlands. No more old males were seen, and the
last female or young was noted on August 18. Two specimens were
collected, an adult male at Hazelton, May 30 (no. 42173), and an
immature male on Nine-mile Mountain, August 4 (no. 42174).

Tyrannus tyrannus (Linnaeus). Eastern Kingbird

Two seen during the summer, an adult male taken near our Kispiox
Valley camp on June 22 (no. 42175), and an adult female at Hazelton,
July 20 (no. 42176). The first mentioned appeared to be in breeding
condition. The Hazelton bird was first seen flying, approaching from
a distance with all the appearance of a migrant. These captures
constitute, I believe, an extreme northwestern point of record for this
species.

Sayornis sayus yukonensis Bishop. Northern Say Phoebe

Apparently not breeding in this general region; at least, none was
seen until the end of the summer. First noted, a single bird, August
23, obviously a migrant. Another on August 24 and two on August 26
make up the total number recorded. These four specimens (nos.
42177-42180), two males and two females, are all in juvenal plumage.
Besides these birds there are two other northern examples of this
species in the collection of this Museum, an adult male from Forty-
mile, Yukon Territory (no. 4594) and a juvenal female from Sergief
Island, Alaska (no. 39815). The adult has been described by Grinnell
(1909, p. 206) as showing the characters ascribed to the subspecies
Sayornis sayus yukonensis Bishop (1900, p. 115). The Sergief Island
specimen has been recorded (Swarth, 1922, p. 224) as Sayormis sayus,
with comment upon its appearance; it is exactly like the Kispiox Valley

specimens. Altogether, this series, one adult and five juvenals, bears
out Bishop’s (/oc. cit.) contention of the existence of a recognizable
northern form of Sayornis sayus. In the young birds from the north,
