6 January 1990. Counted stores: "Main" tree: 150
Small to by nest area: 310
460
It's still a mystery why these birds store so few acorns in their
"main" granary; it's fairly empty and could probably hold
1200 acorns if they worked at it. In all, I'd put capacity at
about 1700 here. Obviously they aren't doing so well, although
they do have some acorns.

1840. Bird in the '89 nest hole. Nesty, perhaps? With 2♀,
it might be worth watching here.

900. Checked the hole: looks not quite ready (but close);
I doubt they've laid any eggs as yet.
