29 Mar 0810 Door to 87b nest hole had Fallen out. I replaced
it, but didn't have a hammer. Saw 1117 (RW). Also
saw NOBA 8, who seemed at home here and was
chasing intruders, of which there were several;
& 1117 was chasing another bird. The NOBA 8 has been
here @ 1 yr, why was he removed?
1140 & 1234 is at Big T
Dec 97 Acorn Count: 5900
11 Apr 0900 Repaired 87b hole
28 Apr 0700 Nest! Incest!(?)! Hatched today. 3 hatchlings and
one egg - in the hole that mom was found dead in
last year. Deep hole. Will cut tomorrow. Clutch 4 = incest?
29 Apr 0800-0900 Cut hole (nice job) RL = 9.1, LL = 10.7, RW = 7.8, LW = 5.6
30 Apr 0815 RL = 12.1 LL = 14.4 RW = 10.7 LW = 7.55
1 May 0830 14.8 18 12.4 10.4
3 May 0630 23.7 (10) = 0 28.1 (10.9) = K 20.5 (9.15) = G 14.4
6 May 0730 Dead Babies. They had been killed. Though the
weather's been bad, the didn't appear to have
starved. All had peck marks. I also Found 2
crown Feathers in the nest. My guess is
infanticide - the breeder 8 (assume it's the
daughter) died and was replaced. However, I
never heard any weirdness here. Baby weights are
as Follows:
16 May 0800-0915 Census: 9 1371 (MV-LB/R) and 1117 (RW) Also
2 88 (I think). I had BDB/LB DB or something like that.
Birds flew to west area, but hello got nothing.
