(26 April) but definite) granary.
I climbed up to the hole and cleared out the
crap brought by the Starling (including 4 eggs) before
leaving.
27 April 1503. A δ (ub?) is at the edge of the hole in the old nest
tree at A3 next to the hole that was used several times
(and the one I cleaned out hier).
30 April Watched roosting here. It was mostly an incomprehensible
mess, due mainly to an intruder being chased from
holes until well after bedtime. In the end, though, I
did figure out where they roosted (not in the old nest
tree - over in the smaller Valley Oak by the granary)
but I don't know how many birds were (rightfully)
here - most likely 3, but possibly 2 or even 4.
2 May 530. Ambushed this morning, nabbing a pair who are
now #651 (δ) and #652. The ♀ had an extended abdomen
and looked very ready to lay an egg - hopefully they didn't
already have a nest in this hole!
I presume, at least for the time being, that these 2
constitute the entire group. I'm also going to guess
that the group was founded back about last October,
since they were certainly here in January and probably
had been all winter (but not much prior to that!)
4 May 1500. 1 bird flushed from the limb with the 2 holes in the big Valley
Oak. If they do have a nest here, it ought to be in one of the two.
5 May 1330. Bird in the hole next to the old A3 nest hole: a nest for sure
1500. Went and opened up the hole; no eggs (!) However,
