2 April
1315. Several birds in the trees over by A1 turn out to belong
from here: ♂ BLK/M
LB/LP-LB #1023 and ♂ M/Red-Yel #835.
2 August
1015. Storage facilities are sort of spread out here, but
my guess is that capacity is on the order of 4000.
This includes ~2500 in the (new) (dead) granary they
built from scratch over on the far side of the ravine
from the fenceline which does, by the way, have
quite a few acorns still stored in it.

11 January
1200. The group here has apparently entirely abandoned their
old storage limbs over by the fenceline, which are all
empty, and has switched entirely to the new granary across
the ravine, where I counted 2050 acorns. I'd put capacity
here at 2500 (for this tree); it's not clear whether to include
those old holes or not anymore! Perhaps the entire capacity
here should be put at about 3000.
2 April
1045. Still some acorns here.
13 April
1550. Some quarrels and chasing here. Watching the granary.
① ♀ NOBA . ② ♂ DG/M
LB/LP-LB #1023. ③ ♂ M/Dr-Yel #835. ④ ♀
M/Red? (possibly
♀1749 from LA2?). With luck, this may be the bird winning.
⑥ ♂ Wh-Or/Blk? (seen well).
⑦ ♂ M/D5
DB/WX(n)/Red #1699. ⑧ ♀ LB? /Red??
Given that there's been no ♀ in this group for awhile, this
activity certainly makes sense as a ♀ replacement.
⑨ Leaving. Not sure who everyone is here, but there's little
doubt as to what's going on.
