mark. For the third year in a row, an adult male has moved from one
colony to the adjacent colony. They say there are lots of tucos this year,
including lots of radio tagged ones from last year (with batteries run
down). John sees mice during the day frequently; his description sounds
like Reithrodon which is supposed to be nocturnal. Maybe Loxodontomys,
although they dont have big ears? Also, his description of the color, same
as the baby tuco he was holding, is not quite right for Reithrodon. There
are many Reithdon droppings around. Only 200 m away I caught, years
ago, a tuco in a burrow early in the evening and then, later that night, a
Reithrodon coming out of the same burrow as the tuco. John says that
they seem to eat Senecio during the winter but not in the spring-summer.
Many colonies seem to be centered around a chacay tree, or a clump of
same. John says it has rained once since they arrived 2 weeks ago.
Novemeber 7- Bariloche. Overnight low 56°; afternoon high 66°. Got the car
back from the body shop and puttered around town. Tommy Christie came
by, might want to buy the apartment. He is embarked on a 5-year course in
software engineering.
November 8- Bariloche. Overnight low 51°; high 64°. Midday sunny, not windy.
At about 10:30 we drove out to the Laguna de los Juncos on Estancia San
Ramon. Road in good shape; 3 squashexd hares en route. The lake is
completely dry, most of the basin covered with short green vegetation. No
water birds, but a half-dozen ibis feeding out in the dry lake bottom. No
condors on the cliff behind Marful's schoolhouse, and none on the cliffs at
the east end of Arroyo La Fragua. The big meadow east of the lake at the
brick factory was very dry, no moisture in the low places. Lots of tuco and
Reithriodion holes, and lots of scattered Reithrodon pellets but not many
big accumulations. Some hare sign. This is much more sign of Reithrodon
than in recent years but not as great as in the year we studied them here.
Then drove east to Marful's gate east of the last cliffs, but his gate was
locked and no car at the house.
At the First Summit we checked for droppings: quite a few Reithrodon,
and Anita found two Euneomys droppings. The Villegas mallin not very
green, and there hasbeen at least one more big fire. Lots of dead pines
behind the school house, the entrance to lower La Fragua Canyon. Almost
no sheep or cattle seen, a few horses. The Notro trees on our street in
town are in full bloom.
Clouded up in Bariloche later in the afternoon.
November 9- Bariloche. Overnight minimum 42. Day sunny, warm, no wind.
Paid bills etc around town: 1.5 hours in line to pay the light and water bill.
went up to Ecotono in the afternoon. Rapoport was there, working on an
edible weeds of the world chapter for a book. He also has a small grant
