(7 October) a very dark eye-I assume this to be a 1st-yr bird molting already
to ♀.
941. The ♂ub up in the FPA eating an acorn and hawking has
a darkish eye and could be the other 1st-yr. bird.
1048. Over in the side storage area is ♀WRW#197 with
an acorn half. At least somebody's still banded here.
The ♂ub Adult ♂ has a few peculiarities about his face:
1102. Near the ♀ is an ub ♂, while up in the
FPA the Ad ♂ub is still hawking. Presumably
this first bird is the 2nd juv.
1115. ♂4el/wn#102 storing in side area.
1130. Leaving. Something has to be done about the unbanded
birds here! But despite them I did fairly well.
As I got out of the hide a bird was in the net, who
turned out to be one of Bianca's 1st-year birds molting to a
♀, ♂303. After doing her I counted stores:
Inner Circle: 979
Side area: 380 } 1359
I noticed 18 of the old marked acorns still stored here as well.
10 October Purge:
♀98. Last seen 4 February (!) Gone by 22 April → Disappeared
about 13 March ± 1 month.
→ (at upper Arnold 2!)
♂98. Last seen 23 April, gone by 18 July → Disappeared
about 5 June ± 1 month.
14 October
830. See Journal for notes on several Gits, at least one from here (♀97)
down next to the road toward the Spring.
930. Set up 2 mist nets. No catch by 1130.
