1200. A bird flew out from what appeared to
be the old nest hole facing the turnaround,
so I went up and checked: 4 (old) eggs,
1 a runt! However, best I could tell They
were very old - too old, in fact. My bet is that
They are way past the possibility of hatching.
I Measured Them anyway: ① 25.5 × 19.3
② 25.2 × 19.3 ③ 25.5 × 18.6 and ④ 19.3 × 14.9.
15 June
1500. Well, apparently Those eggs weren't
so bad after all: There are now 2 kids in
the nest, perhaps 7-8 do!
27 June
1100. Banded + bled the 2 kids. Stores: Yes.
6 Sept.
No stores left here, best I can tell.

Acorns - Yes! Also - The old black oak nest
tree (in between 1st black oak & the valley oak in the
central area) has largely fallen over the winter.
It still has (dead) leaves on it, so it must have
been in Oct. or Nov.
12 May
There are stores still here.
