3 Apr IIII ~50 acorns
Apr Valerie reports a NOBA 9 here (along w 1475, 1696) (?)
4 May Valerie roost watch: only 3 birds, mate guarding???
into "ladder hole" (the old trad nest hole 85,86,87)
5 May Jim reports 1475, 1696, 1398; so Finch effect still
going. Why the mate guarding - or is that just
roosty behavior
Roost watch: 3 birds like glue - I persuaded them
not to go in the ladder hole - one went uphill
squeezed into the "pole hole", the other went
into a shitty hole in the granary, and the third,
well, it didn't go in any. At 1927 I moved
away from the granary or went 100m uphill -
watched the 3rd bird. It stayed there until
1947 (very dark), when Jim made a pygmy
owl call. I hope it will be safe. I vowed
never to keep 'em out of a hole again, but
now it seems I will tomorrow night (I'd ambush
tomorrow a.m., but can't get a lap done on Wednesday
12 May 1140-1215 Spied From afar. Saw 1 visit to the
90 nest hole, maybe 2 visits to the ladder hole
(Leaves were in the way, but it looks like that
was where they were going.
Roost watch: they sounded like they were at the
pole hole, but then they came down to the granary
ended up in the ladder hole. Puk.
