May 31 Russian Gulch State Park, Mendocino Co., Calif.
Of 15 Museum Specials baited with walnut and
set in tall grass under Pinus muricata in
upper reaches of same meadow, not one trap
was even spring! This is exact place a good
catch of Microtus was obtained May 28 (see journal
of this date). We do not believe we could have so
completely exhausted the mouse population in
one night's trapping and rather attribute present
misuccess to the very wet and matted condition
of the grass and runs. Had very slight rain
all during fore-morning, then cleared nicely.
Fran and I walked out to the ocean again
to take pictures and re-inspect the Microtus
and gopher traps which we left set this morning.
At about 2 PM we found a Sorex sp. in one of
the Museum Specials. Nothing in remaining for
gopher traps, so collected them up. About 3 PM,
returning to Museum Specials to collect them up,
heard one snap and found Microtus not in trap,
but convulsing its last in grass 1½' away. Took
pictures of various habitats.
Species observed:
Turkey vulture
Crow
White-crowned Sparrow
Brush rabbit
