12 April
1600. A modest power struggle going on here! About
10 birds or so and a lot of activity.
①♂Dg/m #2231 ②♀ yel/LB #2107
③♂ Dg/M Red/led #2418 ④♀ yel/yel #2416 ⑤♀ M/MV #2420
⑥♂ M/Red #1372. Let me revise my estimate to
15 birds!
1620. Well, I have to go. But with ♂1372 here, this
presumably is over a ♀ vacancy - but with 3 ♀♀
helpers, presumably filling the vacancy won't be easy!
This is actually quite a good show! Hope it lasts
through next week!
13 April
1300. Finally made it back here to set nets (I trained this morning)
and it's all quiet! Maybe it's over already? By the way, there
are lots of acorns still here.

10 April
No one in any holes, but some stones remaining.
17 June
1500. Finally - a nest! New hole in the granary itself.
3 eggs, incubated. 1 measured 24.6 x 20.1.
There are (possibly) a few intact acorns left here,
but not very many!
25 June
1545. 2 kids; 1 weighed 24 g ≈ 6 do (EHD = 19 June)
8 July
1230. Banded and bled the 2 kids.
15 July
1330. Transplanted the 2 avian kids here; at least one of
the other 2 still fine.
12 August
3 dead kids in the nest - ♂ #2710, 2711,
♀ 2712. Only ♀2709 potentially made it.
