Hastings Reservation
25 January 1315. j♂O+RW#164 was in the storage tree; ♂ub and ♀ub
were seen in the vicinity a few minutes later.
28 January 1030. j♂LRW#162 plus a ♀ were in the storage tree when I
arrived. Checking the marked acorns, I found 44/70, of
which 6 had been moved.
The acorn count was 1078.
25 February Watched 1545-1620. Only an unbanded ♂ and ♀ showed up,
presumably the 2 adults. Otherwise they disappeared over
onto Blonquist, leaving the overall activity level low
deed.
1 March 1500. 2 birds seen here again only. I was an unwing-
streamered ♂.
3 March 1015. Watching from hide ♂ub over in perch tree to right of
storage tree sitting
1027. ♂LRW #162 now in same tree, ♀ not seen.
1025. ♂ flew over to storage tree; sitting.
1028. ♂♂ub and ♂♀ both came to storage tree; jawaled with jw. seen.
Birds getting acorn bits and eating them now.
1032. Adults gone, only ♂ remains sitting in storage tree.
1050. ♂ returned to eat some more acorn bits. ♂♂ still here.
1054. Both adults are now eating acorns in a snag in a tree the the
left of the storage tree (the one just over on Hastings about
30 meters left (~SE) of storage tree along fence line.
I stayed until 1200, during which time the birds
returned to the storage tree twice, at 1130 and 1155. All 3
were seen several more times. Unfortunately I'd say
that the prospects for either 163 or 164 look very poor.
