(22 September) 750. 2 birds here: 1♂ and 1♀. 3rd bird, an intruder, flew
down to them but was immediately shagged out.
800. 1♂ or/Blk#173
807. Both now in granary: ♂ BP-? / Blk#484 and ♂173.
810. That's it. Both birds here; no sign of a nest. There are, however,
a few stores (<25) in the granary already. The birds are
doing some storing here already.
12 October 900. No birds in any holes here; also no birds seen. This
group has lots of stores, though: 807.
13 November 1052. ♂ or/Blk#173 sitting in V0 perch tree. Lots of stores here.
14 December 1530. Counted stores: 2530. The granary here is truly
stuffed, perhaps exceeding the glorious winter of 74-75
even. These birds have really done well. They even have
a few acorns in the fallen limb.
I also got a sample of 75 acorns from the tree and replaced
them with my own. I saw no birds coming or going.
1540. As I was leaving I noted ♂ or/m #173 sitting over
in one of the standard perch areas.
1543. ♀ here also, but left before I could get any bands.
