7 June
1600. Finally! 7 fresh eggs. Measured (l: 25.2 x 18.7 mm
16 June
2015. Best I could tell, noone roosted in the nest
this evening (!) What does this mean?
17 June
900. Checked nest: now 6 eggs, not hatched yet. But
a bird was in the hole & the eggs were warm.
20 June
2005. Unless someone is sneaking into the hole very
late, noone roosted in the nest again tonight!
(A g was in the hole when I arrived. She eventually
left and noone came after her.) I think they
have a problem here - presumably related to the
fact that there is apparently no breeder o? here.
I wonder if the eggs are even fertile? It seemed
as though they were developing...
26 June
1600. Hole empty. I'm not surprised, given that noone
roosted in the hole!
1996
4 January
1530. Counted stores: 885, and probably an underestimate
as usual. By far the group in the best shape out here along
the road. Also, 3 birds in holes while I was out here.
17 April
Out of acorns here!
27 April
1015. Bird in hole. (Low hole in dead center limb.)
7 May
1330. Checked the hole: nada. Also cleared out a
Starling nest from the old high nest hole in the main trunk.
5 June
1315. Finally waited long enough: 1 baby, ~10 do! This
means ELED = 13 May! Cleared out a Starling nest in
the high hole again.
