Melanerpes formicivorus
Y
10 May Watching here, 0645-0830. ♂669, ♀714, ♀NB
all here. I didn't see ♀668 today, but I did
see her on 7 May (though I shamefully did not
write it down), working briefly on the new V0 hole.
Today, I saw no interest in any holes, although the
weather (overcast, cool) might have had something to
do with it. When I first walked up to Y, and at
about 0730 again, too, I saw ♂669 and a ♀
up by the Still ravine, in the big Valley Oaks that
contains a hole. I didn't see anybody in or at the
hole, but it merits further attention. Also, the Y
birds still have acorns (saw a few being moved around
and eaten), but I will give them a few more, to
hopefully encourage them to nest.
13 May watching 0610-0740. Starting to get frustrated. Only 2
birds seen all morning, ♀NB and ♂669. Both ♀714 and
♀668 conspicuously absent, although there were some conspicuous
♀NB intruders around. Absolutely no interest in any holes, that
I could see anyway. The 2 birds were almost always in
the granary or on the knoll. Also, ♂669 seems a bit displeased
with ♀NB, karritting and very mildly supplanting her around
the granary. They may at rock bottom acorn-wise, so I
put ~20 mixed lobata + agrifolia acorns in the trunk
of the granary. I'm starting to lose faith in the
hope that Y will nest.
15 May 0920, Things getting worse. I come up and hear
nearly co-stant garricking by ♂669. There
