Cutaneus sonomae

Sep. 9 (2Y mi NW Red Butte, 5300 ft., 14+ mi. S Hayfork, Trinity Co., Calif.)
(cont) of high pitched mellow “pook” or “took” notes
– about 1 note every ½ second. This was about
with binoculars
25 yards from me. After checking to make sure of
the species (since many C. amoenus were also around)
I shot it.
A few minutes later
one came out on the open forest floor, giving the high-
pitched “tchik” or “tsset” series described on Sep 3-4.
It eventually ran onto the same log where the
C. amoenus (see that sp. acc.) was sitting; I had
an excellent opportunity to compare them both
of 9x binoculars
in the field of vision at once.
This one is much larger; the gray tips to the
lateral tail hairs and a tannish area
on the shoulders show up well as field marks.
If the proper angle of view can be had, the
brownish anterior meral surface of the ear fading
into whitish posteriorly can also be noted [of C. amoenus]
