1600. Set up; trying to get 9632 at the nest.
1630. 9 here along with 288. I is 8 mauve/white
1645. Got her!
2 August
1000. Counted stores: Nest tree: 300
Main (dead) granary: 2500 2800.
These trees are pretty full; I'd guess at least 50% full.
Hence, my estimate for capacity is 5000.

18 January
1500. Counted stores here: Nest tree: 1005
Main granary: 3222 4417.
Misc: 190
As usual, the dead granary poses some challenging counting
problems, but in any case the trees are pretty full and
5000 is still a reasonable estimate for capacity here.

1050. Lots of acorns still here, of course, but none in any holes.
15 April
1640. 8 in new hole in nest-tree granary. Should be
easy to climb and open.
1740. Opened the hole, which the birds have obviously been
building. It will be nice soon, but is not quite ready yet.
25 April
1100. None in any holes. Checked the new hole, which doesn't
look much different from when I opened it on the 15th
29 April
1705. None in any holes here. I'm beginning to be concerned;
it's not unlikely that they have something going on the fly here;
I better watch when I get the chance.
3 May
81222 caught feeding nestlings at A1!
1215. Checked over here, flushing a bird from a new hole in the
