15 July Markwood Meadow, 6 mi. east of Shaver
Lake, Fresno Co., Calif. ~ 6000 ft.
Habitat as described 17 June. I started
watching the nest tree northwest of
the westernmost bldg. at 0600 and
finished at 0730 in order to determine
how many juveniles were still using the
tree. Intermittent observations were made
later in the day. I also counted the
cones on a big sugar pine 50 m. north
of the easternmost bldg. There were about
11 small cones which presumably would not
be mature this season, 150 large cones,
and 10 old cones which had already
released their seeds. My impression is that
the sugar pine cone crop is very
heavy this year. I also saw two
sugar pine cones which had been
cut recently and partially taken apart
at the base. The seeds were quite
soft. CBK also found a recently chewed
cone of Western White Pine (P. monticola)
at about 7900 ft. on Mt. Patterson.
These are the first cones I've
seen cut this year.
