7 January
1445. Watching from hide. Still some acorns stored here.
1454. Two birds here- I probably 8611 (definitely banded).
1500. An unbanded 8 eating an acorn in the forest here.
1520. 8ub still here; harrit-culted awhile, but noone came
by to see him.
1525. A 2nd 8, possibly a 3rd bird here.
1530. The ub 8 and 8 M/Da-La #611 here together now.
The ub 8 is definitely part of the group here.
1600. Leaving (a Cooper's Hawk is sitting here making things
difficult). Definitely time to ambush here for the new 8.
I'm not sure what's up with the 8, but she sure isn't hanging
around today.

Valley Oak at the top of UA2 for 10m or so, she flew down to the
garvanry here. I watched her there for >5m, looking a little

8 M/ #611 was in the tree with her. I wouldn't be at all
surprised to find her as a replacement for 8507.

1515. Counted stores: Outer Blue Oak: 150 ?
Inner areas: 33 [illegible]
Definitely something, but it's still hard to understand why
these birds are staying here. But they are-I flushed 2 birds
when I arrived.
I also squeezed out a sample of 10 stored acorns from the granary.
17 February
Ron having confirmed the presence of both an unbanded 8 and
8 here, we ambushed this morning at the rear (Valley Oak)
next hole, getting the young 8 (8611) and the new 8, who
