1500. Checked nest: 3 hatchlings, alive but-
cold (!) Tried to get out as soon as I could
but it may have been too late.
2June Catherine suggested about a week ago at
least that the nest here had indeed failed, and
today I finally checked it, finding it
totally empty.
10August No stores. Plus, it appears that a major
(the major?) storage limb has fallen, leaving
not much in the way of storage facilities here.
