Myiarchus cinerascens
June 12 2 mi SE Beegum, 1650 ft., Tehama Co., Calif.
Common in the blue-oak and digger
pine. Pairs are regularly spaced throughout
the pine-oak woodland at distances
of about 250-300 feet. They call and
move about frequently, and Territorial
encounters are apparently numerous. Nesting
sites for this species are abundant, as most of
the larger oaks, dead or partly living, have
cavities. This species was found on the
slopes north of Camp as well as on the valley
flat, though, of course, over the former area, it
was less frequent because of limited suitable
habitat.
June 13-15 Distributed generally in the woodland
of the south slope, but most abundant
on the valley flat.
2 mi E Hayfork, 2400 ft., Trinity Co., Calif.
June 16-20. Regularly present and fairly common
in the dryer, open stands of yellow
pine, Garry oak, and black oak, as,
for example, along Duncan Gulch and
on the upland west of Big Creek (opposite
Big Creek Ranch). The species is not
present, however, as abundantly as it
was at Beegum.
June 24-26 1 mi W Hyampom, 1200 ft., Trinity Co., Calif.
Fairly common. Present chiefly about poplar and
willow groves on the Hyampom flex. Also present
in open woodland, chiefly Garry oak, near the
top of a south-facing slope above Camp.
