6 March 1230. A fair chunk of the nest tree here has fallen,
including (at least) the 2 upper holes (lowest of
The 3 still OK). plus one other large branch.
Lots of acorns still stored here.
17 April 1630. Opened the lowest of the old holes (the only one
remaining in the old limb); empty. Meanwhile, they
are apparently in a new hole over in the big Valley
oak with The nest box. A project for the next nice
day!
19 April 1230. Opened the new hole in the West box tree
(now tagged #5552). 5 eggs, incubated.
① 25.1 x 19.8 ② 24.7 x 19.9 ③ 24.7 x 20.0 ④ 26.2 x 19.5
⑤ 24.3 x 19.3. (egg #5 not developing).
Note: There's no breeder ♂ on the list here!?
30 April 1615. 4 babies, ~8 do; no eggs. Band ~13 May.
13 May 1000. 4 kids, but somehow one (the largest)
got squished (I guess) and died in the bag (!)
Bummer. So we banded the other 3 and
bled all 4. Acorns remaining: yes.
25 June 1100. Bird in new hole near nest hole; opened it -
still working on it. Nest hole checked also; empty.

6 April 1530. Birds (4?) in 2003 hole: empty, but a
lot deeper and in good shape.
20 April 1210. Checked hole. still empty. Birds interested,
though. Plenty of stores here. ① 24.8 x 18.9 ② 24.0 x 17.6
18 May 1345. Finally! 4 eggs, ~3 dys inc? ③ 24.8 x 18.9 ④ 23.5 x 18.6.
