separating and righting themselves. The preferred nesting habitat
seemed to be semi-open places in the lodgepole pine and aspen forest.

Audubon warblers, probably nesting, were recorded also at
Bouchie Lake, June 7, Nukko Lake, July 8 and Lacroix Lake, July 15.
At Summit Lake on June 30 a pair was seen feeding young; it was
much less common there than were Tennessee warbler, magnolia warbler
and redstart. None was observed at Bulkley Lake, in the Smithers
District nor at Hazelton.

An autumn migration made up of young in, or moulting to, first-
winter plumage was noted first at Francois Lake on August 7; by
August 15 the movement had reached larger proportions. A migra-
tion was in progress at Puntchesakut Lake between August 31 and
September 6

Water Thrush--Seiurus noveboracensis (Gmelin).

In the Baker Creek Valley this species was Race Olen else sky
had not reached the locality in any numbers up to the time I left
there on June 5. Only one was recorded, viz-.; Puntchesakut Lake,
May 3C. At Bouchie Lake and at Summit Lake it was exceedingly
common and was observed also at the following places: Chief Lake,
July 7; Nukko Lake, July 8; Fraser Lake, July 10; Telkwa and
Smithers Districts, July 11 to July 16; Bulkley Lake, July 27;
Francois Lake, August 10

At Bouchie Lake pairs were established in willow and alder
thickets at many places along the lakeshore. The loud, insistent
song was heard at all hours but usually the singer remained con-
cealed in thick cover. Sometimes, however, when I had paddled
along shore close to the alders one could be excited to the extent
of showing itself and would appear Suddenly a few feet away in
the shrubbery. All apparently had left the vicinity when I
returned to Bouchie Lake on August 16

At Summit Lake, June 27, two pairs that were feeding young
came under observation. The bold, fearless behaviour of these
was in marked contrast to that witnessed earlier in the month
at Bouchie Lake. Thus both the male and female of one pair, each
with food in the bill, alighted in a tree only a few yards from
where I stood, and moved about on several bare branches in the
charactertistic jerky manner. Another pair in an open clump of
small spruce made no attempt to conceal themselves and responded
instantly to a 'squeak.' The territories of these particular
birds were a mile or so from water, but at Sumit Lake, as else-
where, the habitat favoured by the majority was the deciduous
growth along the lakeshore.
