1981 R.L. Munne
Melanerpes formicivorus
ARF
20 May Wandered around here 1430-1530. No birds looking
out of the 1980 hole. In fact, no trace that
any birds were even around, actually. I did find
2 fairly new looking W-facing holes in a high dead
stub in a Valley Oak just 20 meters SW of the ARF
granary. Also a Coopers hawk nest (incubating ♀ + 3 eggs)
30 meters NW of the granary.
22 Oct Here at 0745, ARF is occupied! Already several
hundred acorns stored here. Will have to watch to see if
anyone here is banded.
22 Nov Trying to do just that, 1215. I can see about 300 acorns
or so just from where I'm sitting. 1345. A poor day to
watch. A few karrits, but nobody has come to the
granary. A few weeks ago, I remember seeing
3 birds in the granary here at one time. So
there should be at least 3 birds in the group. I'll
have to try again.
2 Dec Making another try here, 0845. 0950, well, it looks
like 3 unbanded birds (Drat!), 2♀ (I'm pretty
sure) and 1♂. I had a brief impression there
might be a 4th bird around, but there was a lot of
intruder activity here, so I couldn't be sure. Anyway,
I'll definitely have to look into the possibility
of an ambush here. end. 0955
