S. varius ssp.
17.5 mi. S. of Quesnel, ft., British Columbia
Junell (cont'd) big, dark, nuchalis, but the white
post-ocular stripe was completely obscured and
the black pectoral band was narrow. It too
worked back (east) into the aspens out of
sight. I looked around in the grove but did
not see or hear them. As I returned to
the road another bird came up gathering
insects low and almost on the ground, like
the others. This one was absolutely typical
nuchalis. (Few minutes later) - I just found the
nest - about 35 or 40 ft up in a big aspen, live,
about 18 or 20" in diameter, facing NE. It
is the only hole in the tree. I saw both
the above-described birds go into it, and they
are feeding young. One, the darker and in
all probability the ♂, cleaned the nest. A good
look at him shows a normal pectoral band,
and it is quite possible that he is not an
intermediate. [collected, June 14; TRH #s 414-15]
McCleese Lake, ft., 20 mi. N. of Williams Lake, B.C.
June 11 (cont'd)- This is an attractive lake, with
conifers and mature aspen and cottonwood around
it. I found two nests, both in aspens, and
with parents feeding young. All were typical
[see June 18]
nuchalis, as expected. One nest was only 7 or
8 ft. up in an aspen about 12 in thick, the
other about 25 ft up in a slightly larger tree.
I would estimate the age of the young as less
than a week. The parents went in the nest
to feed, and often stayed in until replaced-10 min.
