(5 Aug) If they were around, this certainly should have brought them
out of the woodwork, unless they are off exploring.
0900, speak of the devil, ♂580 m / B1K shows up, opening
walking with everybody in the 1° granary. ♀578 is still missing,
hower. 0915, Pretty much all over here, save for the usual
post-revolution friendliness, opening wakas, etc. End watch.
Note: Finch is out of acorns, which probably had something
to do with that invasion.
16 Sept A quick pass here 1530. There are still a few acorns present
in the granary. Nobody in any holes, but I did run
across ♂294, BPink / DBlue-yellow, ♂580, wnt/B1K, and
♂579 wnt/m. Whoa, also J672 in ♂ plumage!!
Another ♂!
10ct Start watch 1400. Granary Census on back. Storing has begun
here, but not really in earnest. Only a few new acorns. I'm also
quite certain that they did not run out.
1600, Very slow
afternoon. Helpers 577-580 all see, ♀383, (perhaps
♀269), and J♂672 only birds seen. Very little action
in the granary, only one acorn seen stored.
6oct Another granary census, 0800~1000, [illegible] Bitar, Lots of
storing action this time, although the pace slowed to
a near stop toward the end. Good census, all 4 helpers,
♀383 ♀269 ♂446 all see. Only ♂294 and
J673 missing. The latter not seen since 5 Aug, is
perhaps gone for good. Will leave him on the field
list for the time being, though.
