1988 M. Stanback M. Formicivorus Y H NHR 28 Mar 1030 Saw 7 675 (gwl/m) at Barn, also 8 1150 Dec 87 Acorn Count: 420 3 Apr 0930 7 1350 (old Y H/B and present Knol PB) was here getting chased around the barn by a Y bird. 7 Apr 1450 Eagle eye here spots bird in hole. Need a ladder. 10 Apr 0700 Bird at 87 hole (again 1110) 1400 Check hole - empty, but looks good. 11 Apr 1200 1 Fresh egg - can't reach it (neither can Jane - damn) 12 Apr 1800 Morgan can reach! She takes out the 2 eggs and I put in wood chips to the desired level. #1 + 2 . 23.3 x 19.55 13 Apr 1720 Labeled egg #3 24.55 x 21.05 • (3) 24.05 x 20.66 14 Apr "" 4 24.9 x 20.7 • 15 Apr 1300 "" 5 25.4 x 20.85 18 Apr 1800 6 eggs 24.85 x 20.35 26 Apr 1600 None hatched yet. 27 Apr 0550 RL = 4.2 LL = 4.15 RW = 4.5 Eggs #1 + 5 pipping, eggs #6 not yet pipped. Because I weighed them before any feeding occurred, I think the size dits reflect egg size dits, ie RW From biggest egg. Bropped 1210 RL = 5.6 LL = 5.22 RW = 5.55 B = 3.7, LW = 4.6 As eggs 1-5 were at the same stage of pipping this am, I will assume that LW (bigger) came From egg 5 and that B came From egg 1. Yes, I dropped RL @ 8 inches. 28 Apr 1145 RL = 8.8 LL = 7.9 RW = 8.45 LW = 6.4 B = 3.55 3.7 29 Apr 1215 13.1 9.5 10.8 8.27 ↓? 3.25 30 Apr 1200 14 12.5 13.8 8.97 1 May 1150 18 14.9 15.5 8.8 (red scale)
