Much fussing around, less storing. Many acorns (almost all Q douglasii (?) stored. Juv. 504 a confirmed ♂? Don't know if ♀483 is still with us.

After about 1030, storing of new acorns declined, the ♂♂ began to work on transferring acorns and refurbishing storage holes. ♂504 much less prevalent in this aspect.
I recorded only about half of all the storing. From 1015 -
1030, nearly continuous, and I couldn't keep up.
Birds were poking around in a cavity (just proximal to the "high ladder hole" and ♂234 entered briefly on one occasion. Don't know if it's serious. End watch 1200.
18 Nov Start 1130. ♂252 chews Nut hatches twice. ♂234 also Red-DBlue/Red DBlue here briefly. 1205, ♀483 " " here!
