24 May Earlier this month we kept hearing birds nearby while
we were watching Fanny Arnold, but these birds did not
come over to Fanny Arnold. Today I finally watched
and discovered ① yes there does appear to be a new group
here ② it seems to consist of an mb pair ③ they have
a nest and appear to be feeding babies (not dipping yet).
See "Fanny Arnold" notes for details esp ④ of today's watch.
I hear no noises from the hole: maybe they're still incubating.
25 May 1600. Opened the nest: 4 hatchlings, 2 of whom are on the
way out. Actually, this is probably day 1 for them.
These birds will be given a founding date of "0" April.
3 June Had a net up in front of the hole, 1430-1630, no luck.
The babies were in there, however.
9 June Netted this morning and eventually got the ♀ as #1098.
13 June 400. Ambushed at the nest this morning but only #1098 was
in the hole (unless The ♂ got out before I pulled the
string!) ! Also, There are only 2 babies left here.
15 June 1030. Banded the 1 remaining baby as #1102; the 2nd baby
was dead in the nest.
Missy tried to catch the ♂ afterwards.
31 December These birds petered out fast on or about the time
I banded the baby (who I suspect didn't even fledge).
*Group Update*
Missy played the tape and got only Fanny Arnold
birds on 3 July, so they were certainly gone by
then. Baby NSAB; Adults Abandoned (NSA) →
24 June ± 1 week.
There is no separate group here any longer.
