Melanerpes formicivorus
Fort Hunter Liggett, ~5 mi. N. Jolon, Monterey Co., Calif.
12 January
Today, despite fair-poor weather conditions (rain fell
most of the day), Ron Mumme, Larry Hawks, Nancy Toste, and
I all traipsed out to Hunter Liggett to make a brief
survey of the acorn and woodpecker situation there.
We arrived in the area at 1130 and spent approximately
3-3½ hours checking out several areas. Basically, we
looked for 1) signs of a good acorn crop, i.e. acorns on the
ground, and 2) the state of granaries, i.e. what proportion
of granaries appeared to be unused this winter. This latter
aspect presumably gives an indication of how large the
population is here, though I do not have any baseline
with which to compare my figures.
The 3 areas we checked were 1) an area near Hay Camp
Road, 2) an area on Hay Camp Rd. out near San Miguelito
Rd., and 3) an area on the San Miguelito Loop several miles
down from Hay Camp Rd. A map with a general idea of
where these places are will hopefully be found on the back.
The entire area was quite wet!
As for the acorn crop, it's clear that it was generally
very good-excellent in the areas we checked. Quite a
few Valley Oaks and at least a few Blue Oaks were had
literally thousands of acorns still littering the ground
below them. I didn't note any acorns still in the trees, but
it's very likely that some Live Oaks still did have some acorns.
In granaries I noted all acorns of all 3 of these species.
Valley Oaks were definitely in excellent form this year here,
and a fair proportion of trees had many acorns below them.
