4 June Sat around for a bit here this afternoon; didn't see much. I think that they're out of acorns here, however.
7 June 1010. Watching from blind. They do appear to be out of acorns here.
1100. In 1st tree: ①♂ Blue/Red-Or(N) #1608 and ②♀ Grn-Or/Yel #1609.
1110. Things are pretty slow here, but at least these 2 birds are around, if not doing very much. Leaving. Little sign of a nest or of #1610.
1 August 1640. Still no acorns here.
As for the number of storage holes, I didn't count them but I can see no major blocks of new holes here since my counts 10 years ago. My guess is that the 2nd tree does have some additional holes (300? more, maybe), but I do not see much potential for a big gain over my old counts here.

8 January 1145. Counted stores: Main tree: 550 787.
2nd tree: 237
There's something wrong here: The Main granary isn't more than 20-25% full, if that. What's up here? There are so few acorns stored that I can't even really take a stab at the capacity here.
5 April ♀1609 seen at Weate power struggle; see notes.
12 April 925. ①♂ #1608 in fight with scrub jay on lower sap side, where he was flycatching.
930. ②♀ /Yel #1609 here also.
940. No sign of anyone else! Birds flycatching, eating catkins,
