4 April Spring grany census & watch for signs of nesting, 0745-
0945. 9269, 9383, 8486, 8244, 8579, 8580, 8672
all seen. 9578 not seen, and 9804 seen fleetingly, but
not convincingly. The important news is that the birds
are indeed excavating a new hole in the new sycamore
along the creek. Also, it looks like a bit
of mate guarding is getting underway here. 8486 seems
to be following 9269 fairly closely, although it looks like guarding
is not in full swing. Also, I think 8486 spent a fairly
long bout in the hole by himself, suggesting that
guarding is not completely sure, yet.
Back in the afternoon, I climb up (not too bad,
with rope ladder) and saw open the new hole (a little thick,
but not too bad), to find that the hole has a way
to go yet. Not very deep, very narrow inside, and a
pointed bottom. Still should be some time, if they
use this hole. (Possible my opening will scare them
off).
5 April Aquiots look 1015, I find a 8 (9269?) looking out of
the new hole, so I appear not to have scared them off.
6 April Grany census, 1415-1615. Lot of action around the
new hole, but not that much action at the grany.
8486's guarding of 9269 is still quite weak,
it indeed ho's guardig at all.
7 April Checked the new hole 1440, lots of progress has been
made! should be ready for eggs within a week.
