9 April
& MPHF birds here in the granary (Which has no
acorns). What's going on? No chasing or anything;
indeed, there's no sign of the LPHF birds at all.
9 June, 930. Birds (inc. & or/or ? #1863) are in the ravine next
to the road, interested (but not obviously using) a hole in
a large live oak here. Maybe they're starting a nest?
Meanwhile, in the vicinity of their last year's hole are
birds who keep flying up to MPHF and presumably belong
there.
945. Also here: & wnv/vel #2075. Birds going to hole regularly,
but no one has gone inside or fed or done anything to clarify
why.
16 June
930. Bird (♂) in hole!
1100. Hole peeped: empty. But they are definitely interested.
1200. & here: &/m #2075 again. Perhaps the breeder ♂
is gone? That would explain a lot.
6 July
1630. Bird in the hole again. Also, Veronica claims to have seen
the ♂ a few days ago.
7 July
830. Hole checked. Empty, best I could tell. Certainly no
babies in it, at any rate.
