Big Tree
Hastings Reservation
6 May
1545. Nobody in hole.
10 May
1545. Bird in hole. Nest o.k.
13 May

Counted acorns: 73.
17 May
1645. Bird flushed from hole leaving screaming babies. I,
needless to say, departed immediately (this is the only active
nest left up here that I know of!)
21 May
1500. To my surprise (and delight!) - the nest is still on here; I
couldn't tell positively, but through my mirror I could see 3
babies at least.
24 May
※ 1735. Babies heard loud and clear here.
27 May

31 May
1130. " " " " "
5 June
1510. " " " " "
9 June
1430. Banded the babies, of whom there are 3, as #403, 404, 405.
They are a little thin on this fogged-in day, but looking alright.
1910. Nestlings making lots of very-nearly fledged sounds.
15 June
1910. At least one nestling still in the hole peering out. Otherwise
I checked the granary, which as expected is functionally pretty
much depleted as far as I can tell - I did see 4 good acorns
two however perhaps questionably so and the other 2 very low
and more or less hidden in the granary.
17 June
1800. At least one or two of the fledglings are out making a racket
in the main forest area here. One was still twittering like crazy from
the nest hole.
3 July
730. I can still hear some fledgling sounds coming from this
area.
