Cutamias amoenus -1-
Sept.6 Red Mtn. 14 mi S Hayfork 5300 ft. Trinity Co. Calif.
There seem to be a lot of these small chipmunks in this locality. They are much more confiding, forage in the open more,
and scold persistently from exposed positions in direct opposition to E.
amoenae and townsendi. Their
habitat seems to me intermediate between
that of amoenae and townsendi. They
forage in the trees growing from
Coarthus tangles and on the open
forest floor, running around freely on
cogs and coarse ground litter. They flick
their tails quite constantly while foraging
and run for the nearest stump or log
butt to examine the situation when
disturbed. Their calls are intermediate
in pitch, giving both a warning
"chee-chee-chee" very rapidly and a lower,
steady 2 or 3 per second "chit-chit-chit-chit",
each note being accompanied by a flick
of the tail. Brown tipped guard hairs
on the tail with a strongly bicolour ear
and whitish face are good field marks.
Sept 10 same locality - After several days watching
chipmunks it is apparent that these animals
are rather restricted in their range here,
and perhaps at about the lowest elevation
