13 June
81234 over at LA2. See LA2 notes. He was eating an acorn in
the granary.
20 June
While trying to see LA2 birds in the Top Tree I seem
to have come across j1715 from here trying to beg off
one of The LA2 88. See my LA2 notes.
25 June
See LA2 notes. 81234 over at LA2 regularly; I think he's
back there. Also I saw j1716 in the Top Tree!
26 June
1730. Saw ① j R-won) 1717, ②♀ wh-bik/M #1565, and ③♀? yel/bk #1319?

11 January
1015. Found no sign of any stored acorns in the nest tree, where
there are a few holes at least. My guess is that the group here
is gone, at least for the winter. (I did look around some,
and found no sign of stores elsewhere.)
2 April
1015. No birds in evidence here.
5 April
1055. 9 here along with some chasing.
22 April
81234 looking at home over at LA2; perhaps he has moved
back there?
27 April
1145. 2 birds, a ♂ and ♀ M/(cn) #1319 in the nest tree. This
group apparently lives after all!

24 May
1515. Watching. 1545. ♀ M/(6-w/cn) #1319.
1600. Got to quit. Checked nest: 3 babies; biggest weighs 30g (~6 lb)
2 June
1605. Watching; trying for ♂? 19' or (by any chance) a ♂?
1720. Quitting. Going to bleed the kids.
1730. Still 3 babies:
