21 January
1030. Counted stores: 1242. Tree is quite filled up here.
2 April
Lots of stores still here when Erik & I came by to add a
feeder.
4 May
1545. No sign of a nest, but lots of acorns and even a bird up in
the granary.
5 May
1930. 4 birds here, quite vocally, at roosting. Lots of karrits,
pre-roost mounting, interference, and even chasing, but I
think they all belong here. Three apparently roosted
somewhere across the ravine, while I don't think
anyone roosted in the granary - even though they spent
all their time there until the last minute.
13 May
830. Checked both holes, which are empty. The top one (at
least) is in excellent shape, however.
15 May
945. 23 birds in sycamores. Flew across canyon, then
returned to the granary. Still none in either of the
holes, however.

④ 24.8×18.7 ⑤ 26.7×20.1 ⑥ 26.9×20.3 ⑦ 25.9×19.1, Stanback had
marked the 1st 6; the 7th was new.
