The Marten and the "Mac" Marmots
By John R. Rowley, Ranger Naturalist
I was set up to take pictures of a
young marmot whose talus slope burrow is located north of Llao Rock. On
several earlier visits I had found the young fellow to be sufficiently
curious or uninitiated that he would come out of his underground home,
looking up toward me from his ridiculous sitting position with his
little round belly resting on the ground between his not-long-enough
hind legs. My little friend had sat like this several times in the past,
with forepaws held primly in front of him, looking toward me with as
much interest, it seemed, as I showed toward him.
However, on that day all was not well
on the precipitous marmot rock pile. The little fellow came out within
minutes, but two adults - - some 60 feet distant - - were constantly
giving the alarm cry of the yellow- bellied marmot. Their cries could, I
thought, be directed toward me. No, there was a red-tailed hawk sailing
slowly overhead; this was probably the cause for the marmots' unusual
display of alarm. The short, shrill cries continued, though, long after
the hawk had disappeared far east along Crater Lake's rim toward
Cleetwood Cove.
Then, without warning, a small
mink-like head, rich brown in color, peered from behind the large rock
just below the young marmots' hole. It was a pine marten, fearless,
pugnacious animal, smaller and more slender than a domestic cat.
The young marmot disappeared into the
burrow; the marten, after a hasty look about, which included a glance in
my direction, followed. After a few seconds, the marten reappeared and
for a time was lost among the rocks. Once more I saw my little friend's
nose with its knowing expression. But the sharp, warning cries of the
two adults, sitting up like overgrown golden-mantled ground squirrels,
sent the young fellow back out of sight.

Yellow Bellied Marmot
Once again the marten appeared, eyes
gleaming, head bobbing. He entered the young marmot's burrow, this time
coming out of another exit. Smelling the rocks about the area, he once
again gave me a fearless glance - - a glance that made me feel the
tenseness of the moment acutely - - before he again slipped into the
main entrance.
After many seconds, the marten
reappeared and poised on the large rock with my little friend clenched
shapelessly in his jaws. Quickly now, the marten carried his prey down
the rocky slope and across a small pumice meadow to the shadow of a
Shasta red fir. Here the marten put down the marmot, looked toward me
and toward the two adult marmots, his body vibrating intensely. Then,
picking up his plunder, the marten disappeared into the depths of the
forest.
Now one of the adult marmots went into
action. Whether my presence had prevented earlier defensive activity or
whether they had not actually seen the marten, there is no way of
determining. I had thought of the marmot as a slow animal, moving lazily
about on its short legs. This conception was soon to be altered, for
this adult covered the 60 feet of rough terrain between his burrow and
that of the young marmot in a matter of seconds. On arrival he sat up
and gave three shrill "chirps" before dropping into the burrow, tail
bristling so strongly that it approached the size of his fat body. The
adult marmot soon returned, sat up straight for an instant. Then, with
the bristling tail trailing like a pennant, he returned to the home
burrow as quickly as he had come.
For the next ten minutes both adults
sat upright, giving their shrill chirp every few seconds. One of the
adults began to run toward a pile of rocks that stood on the edge of the
pumice meadow and, to my surprise, a marten dodged from behind one of
these rocks. The marten sped from the lumbering marmot with a swift airy
grace, possibly very soon, by taking to the trees, to complete his
escape.
