7June watching at granary 1130 for signs of either juvenile dominance
or a possible 2nd nest. Idling the time by, I count
about 400 acorns in the northern branch of the granary
visible to me. These guys are definitely doing well.
1300. Complete census, ♂638, ♂639, ♀640 and ♀NB
all seen quite well in the granary. No juveniles seen,
so I guess they are still a bit young. No evidence of
♂ associating with particular ♀, so I guess that's
some circumstantial evidence suggesting that a renest is
not in the immediate offing.
1330. Checked the nest hole. Empty. All 3 babies
Fledged (I would guess) and no new nest.
22June Climbed up to a stuck my had over the nest hole at 1100.
Nothing, so I would guess no babies + probably no eggs
Since no adult in the hole. It might be worth watching
here in a week, just to make sure they don't have another
hole (I said hello to the granary holes, no response)
18July Watching from behind trees near the granary. 1010. 1120,
Not much action here at all, we save for J658 M/LBlue-A1K
LBlue-BK/LBlue
Flycatching from the granary abit. A couple of adults came by
but no good looks. Still plenty of acorns in storage here.
12Sept Tried to watch roosting See M1 notes. No idea where
anybody
14oct Watching here 1615. These birds have not wasted any time.
The granary is already loaded with acorns. Looks like mostly live oak,
Some Valley. Might be a few "leftovers" from last year, but not sure
I count 506 just from where I'm sitting. 1715, Nobody shows.
