1300. Attempting to count stores here!
8575. There are a lot more holes here
than there used to be. I suspect that
there actually could easily be on the order
of 10,000 stored acorns here.

1130. Bond in traditional hole (tag #247).
Checked it: empty but in good shape.

1300. Bond in old hole #247 in The 2° tree:
5 eggs (1 a runt), fresh.
4 June
1000. Checked the nest: now 1 hatchling +
5 eggs, (1 a runt). Guess they were still
laying on 5/24 (LED 5/25).
7 June
1045. Still only 1 kid + 6 eggs (1 a runt).
Must have been miscounting all that time.
3 of the eggs had not developed at all
(not including the runt); I collected the
2 that had and took tissue from them.
Both embryos (4749/50) were alive but
nowhere close to hatching - they must have
been laid very late in the game. They
were ~15mm in length.
