At Home Along Lost Creek
By Mrs. Marcella Stine
We returned to Lost Creek on the 15th day of June, 1955. Almost
immediately we found that a pair of yellow-bellied marmots, Marmota
f. flaviventris (Audubon and Bachman), had made their home under the
old barn. During the summer we watched their comings and goings with a
great deal of interest.
On July 9th, I happened to walk by the barn and, much to my
surprise, saw two baby marmots. Upon looking around I found two more
babies. I hurried home to tell my family of the discovery, and together
we went over to watch them. After a few minutes the babies began to
appear first came the four, then another, and finally three more. Eight
baby marmots! They were very unsteady on their legs and fell all over
each other as they played.
They seemed not to know the meaning of fear and paid no attention to
us. Suddenly we heard a loud thumping of feet as one parent came rushing
through the grass. The babies scurried into their home -- all except one
curious little fellow. He apparently decided to have another look. All
at once he let out a sharp squeal and backed into his home. I feel
reasonably sure that mamma spanked.
After lunch we again went over to watch the babies and to count them
once more. 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9--my daughter Sandy counted
10. Goodness, that just couldn't be -- ten in one family? There were two
adults; these must have been the parents. Surely there wouldn't be two
mothers and no father? They were all out now, playing like kittens. We
counted again. Sure enough, there were ten. We sat about ten feet away,
watching them play until the parents came home and shoved them in.
Much of the next three days was spent in taking pictures. I managed
to get one which included all but two of the babies. By the end of the
week they were venturing a hundred feet and more away from home.
Eight of the ten young marmots in the colony at
Lost Creek; one out of sight at the left of the photo.
The adults were doing a fine job of teaching. The youngsters became
more timid and would scurry into their home when we approached. The only
way of getting pictures after July 17th was to catch them unaware --
which was almost impossible -- or with a telephoto lens. And how I
wished that I had such a lens!
The barn stands in a direct line of sight from our cabin. With
binoculars we continued to watch the marmots from our door. They still
played quite a bit, but they scurried home at the slightest sound.
By the 20th of July, the young went with the adults in search of
food. Then we would see them only in the early morning and after 5:00
p.m. During the last week in July there was no sign of either young or
adults. I feel that they must have moved elsewhere, due to the many
attempts made by visitors to capture them.
On August 14, I was surprised to see one of the young sunning itself
behind the barn. I haven't seen him since, although I have gone there
frequently. I have seen evidence of many visits in which he returned
with grass for his winter bed.
We have received so much pleasure from this marmot family that we
hope very much to find another under the old barn next spring.
Editor's note: According to Victor H. Cahalane (1947. Mammals of
North America. New York, The Macmillan Co. x, 682 pp.), a marmot
litter usually numbers four or five and has extremes of three to eight.
A family of ten for a single mother would be very exceptional, although
perhaps possible. However, frequent and intensive observation convinced
Mrs. Stine that one of the two adults was a male. Furthermore, the
presence of two females in an area with no evidence of any male would be
rather unexpected, especially in view of the fact that yellow-bellied
marmots are quite sociable animals. If one assumes that the two adults
observed here were not both females and each mothers of a litter, it is
also possible that one was a mother caring for, in addition to her own,
the offspring of a family whose mother was killed, while the other was
the father. In any event, this observation is an unusual and intriguing
one. --- R. M. B.
The Giant Meadow Mouse
By Orville Page, Ranger Naturalist
The meadow mouse is rarely seen in our park, especially in the
daytime. On the morning of July 17, 1955, it was my privilege to observe
for a few moments two mice which I am reasonably certain were giant
meadow mice, Microtus richardsoni arvicoloides (Rhoads).
My destination was Godfrey Glen and Duwee Falls, in the steep-sided
Annie Creek Canyon. A short distance above Godfrey Glen, I crossed a
very lush meadow area. On the upper slopes of the meadow were some small
springs which formed little streams of water about six inches wide and
three inches deep. As I approached one of these streams, a splashing
commotion was heard. This turned out to be caused by the two giant
meadow mice. They seemed frightened by my intrusion and began to swim up
the little stream. The mouse in the lead swam along for about eight feet
and disappeared into the grass. The second mouse swam a little way and
then hid under some grass that drooped over into the stream. Only his
head was visible. He apparently felt insecure, and before my camera
could be focused, he followed the other mouse on up the stream and
disappeared.
Meadow mice are often found around water or damp places (Cahalane,
1947; Wallis, 1947). They are very good swimmers. One meadow mouse in
Michigan was observed to swim about eighty feet, part of the way under
water, to escape capture.
We have many little animals in the forest that are not seen unless
one gets away from the thickly populated places. While out strolling
through wooded areas, the lover of nature probably enjoys most those
moments when he encounters some forest animal going about his daily
living habits. These forest friends will continue to live in their
natural surroundings as long as the National Parks maintain natural
wilderness areas. The National Parks belong to you, as an American
citizen. Only your constant vigilance will keep them in their present
primeval setting.
