(17 May) ① 26.0 × 19.3 ② 26.5 × 18.9 ③ 27.1 × 18.3 and
④ 26.5 × 19.2. (Calipers checked) Could
be a final experimental group.
21 May 1945. I scared a bird out of the hole when
I arrived, but despite plenty of time for someone
to return and roost, noone ever did as best
I could tell. It would seem as though
I may as well collect the eggs!
22 May 1130. Eggs warm; collected them for the
least (6th) experimental removal of the year.
12 June Still stores (up in the VO over toward LA-2).
30 August Pretty much out of stores.

12 March Lots of acorns here, up in the VO on the knoll over
toward LA-2.
17 April 1645. Opened the new hole in the granary on the knoll:
4 fresh eggs. A potential experimental group.
21 April 1330. Took the 4 eggs (exp #5). Measurements:
① 26.1 × 18.4 ② 28.9 × 18.4 ③ 26.1 × 18.2 ④ 27.8 × 18.2
10 May 1145. Checked the old nest hole (tag #1146):
empty.
13 May 1100. Turns out it's a new hole in that tree,
out on the one remaining live limb, now tagged
#5802. 4 eggs, Incubated, ① 28.0 × 18.2
② 26.6 × 18.2 ③ 26.4 × 18.5 ④ 26.9 × 19.0
4 June 1300. Banded #616d the 4 kids. Lots of stores.
