Perisoreus canadensis canadensis (Linnaeus). Canada Jay

Fairly common, both at Careross and about Atlin. At the time
of our arrival, during the last week in May, old and young together
were roving through the woods in small bands, apparently family
groups. During July both old and young were going through the
molt; specimens of adults and young collected on August 14 had com-
pleted the change. Seventeen specimens were collected (nos. 44783-
44799), including three summer adults (two from Careross), seven
in juvenal plumage, and seven adult and immature in fresh winter
plumage.

Corvus corax principalis Ridgway. Northern Raven
This is another species that appears in the Atlin region in the fall.
Kermode (1914, p. 21) found it common there during September, 19138
(recorded as Corvus caurinus). Seen by me on just one occasion, at
Lake Teslin, September 12, when two birds appeared, attracted by
refuse from the carcass of a moose that was being cut up.

Euphagus carolinus (Miiller). Rusty Blackbird

One bird seen at Carcross, May 24, but the species had probably
arrived some time before. Upon our arrival at Atlin a few days later
we found scattered pairs established in most of the little swamps that
are distributed throughout the lowlands. Small flocks of young
appeared in July, but the species was not abundant at any time, and
most of the birds had gone by the middle of August. I saw a few
at Gladys Lake, September 8 and 9, the last I encountered, though
Kermode (1914, p. 21) has recorded it from this region as late as
September 19.

Carpodacus purpureus purpureus (Gmelin). Eastern Purple Finch

On June 25, near the town of Atlin, I heard a purple finch utter
a few notes of its song, and on June 28, at the same place, I collected
an adult male (no. 44800). This constitutes, I believe, the extreme
northwestern point of record for this species.

Loxia leucoptera Gmelin. White-winged Crossbill

First seen on June 3, a single bird. Increasing numbers arrived
daily, until by the middle of June flocks of fifty or sixty birds
