1130. Hole empty! Burner!

Still lots of stores.

5 Feb.
Ambushed the usual hole (in the outer Vally Oak)
This morning, getting the NOBA ♀ (now 4032),
83034 + 83038, and a surprise - 93367,
a daughter not seen since Aug. 2001!
Bizarre. She has to be a helper (the 80's are
her dads); presumably she's now outranked by
the NBA ♀.

1615. Bird in one of the old holes back in the forest:
The lowest hole on that limb that used to have at
least 3 thit (now this is the only one left). Hole
has 6 eggs (1 a runt): ① 24.8 × 19.2 ② 18.0 × 14.8 (Runt)
③ 26.2 × 18.6 ④ 25.3 × 18.9 ⑤ 25.3 × 17.9 ⑥ 24.0 × 18.9.
Fresh. Hole now tagged #903. Perhaps both
♀♀ are laying? Incest?
19 Apr 7
915. Took the 6 eggs for the 3rd experimental
removal of the year. Inc the 5 normal ones.
24 Apr 7
Eggs (2) hatched this morning.
10 May
1545. Bird in hole #903 again. 7 eggs, incubated
(1 a runt again!) ① 25.8 × 18.7 ② 25.0 × 18.8
③ 25.0 × 18.3 ④ 26.2 × 19.1 ⑤ 25.2 × 18.4 ⑥ 25.4 × 18.3
⑦ 21.3 × 15.1 (the runt). EHD ~ 14 May.
