Milanerpes formicivorus
Plaque
(15 October)
*Woodpeckers rarely in 2° tree. Nuttatch also seen
carrying away a [smallish] acorn harvested here.
1500-1515* (15 min.) 27
*No chasing by the woodpeckers again.
Clearly the woodpeckers don't stand a chance when it
comes to competing with the jays under these circumstances:
that is, a very concentrated area of food. I might add
that a similar level of jay harvesting by jays was first
noticed yesterday morning; clearly after only 2 days
of this they must have harvested several thousand acorns
from this one tree.
16 October Day activity is definitely down finally. One 15 min
watch was done:
Jays Nuttatch
1145-1200* (15 min)
8 1
*The woodpeckers were in the vicinity some of the
time, mostly hawking, which they never did yesterday.
26 October 1200. Counted stores:
Main Tree [Plaque]: (10+7/6)? 11.59
2nd tree: 31
9 November 1510. 2-3 birds here. ♀ or #22 seen.
21 November 1000. The 2 banded birds up in top of the 2° storage tree.
1145. Only the 2 banded birds seen sitting around. Woist dordreiste?
6 December 1645. Both banded birds seen; ♀ first seen in a sycamore
up Madrone Canyon. While watching these 2 together
a 3rd bird (♂ub) flew from Plaque (?) to the trees by the
upper barn; I presume this to have been the ub ♀, but he
behaved slightly furtive and perhaps was someone else.
If so, the 3rd bird may very well be gone.
