1976 Walter D. Koenig 26 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.
