1530. 2 birds (nowing-streamers) flushed from the storage
tree when I arrived.
Checked marked acorns, finding only 23/60, with 5 moved.
There are a few Q.agrifolia acorns stored here, in case
I missed them with my sample.
Count: 944 (this is very hard to count, of course, but there are
still a lot here).
1615. Surprise. 5 birds, all tame enough to come land in
the storage tree while I was standing below it, did so
and began working stores together, as if they belonged
here; the catch is that none of the 5 were banded.
They included 4♂ and 1♀. After 6-7 minutes they
flew over to the sycamore roost area, again as if they
belonged here. At no time did anyone protest. At this
point I will not even bother to stab at what's going on.

945. Watching sans hide. A bird garricked over past the sycamore
roost trees out of view. Several birds over that direction.
1010. Over below the far BlueCale roost tree a bird popped up who was
a ♂ and I believe banded and possibly #234.
1030. After rechecking the storage/roost area, and still hearing some tapping
downslope toward the 3 ponded fork in Matrone canyon, I went
down to the fork, but did not come across any more birds.
1045. Now returning via the gulch, 2♂ were up in the storage tree but
could not be identified. They flew over the gulch to Tregas's side of the
canyon at 1050. Meanwhile more drilling continues downslope
from The sycamore roost area by invisible birds.
1100. Noone's returned. I'm off-
