800. Checked the new hole above the exclosure, even
through there wasn't anyone in it: zilch.
12 May
1300. Bird in the hole at last!
1315. Well, it's still empty, but at least I think I can
be fairly confident that they will nest here.
16 May
900. Still nothing! This is becoming worrisome....
22 May
1415. Well, we did miss the 1st nest - There are fledglings
here. But at least I found the 2nd nest - it's in a new
hole in Tree#2 facing into the exclosure. This is probably
where the 1st nest was as well. There are now 3 eggs
incubated: ① 25.2x20.0 ② 24.6x19.7 ③ 24.3x20.2
(egg#3 doesn't appear to be developing). I set an
ambusher, hopefully to facilitate catching the 1st brood.
25 May
1900. Shit! The ambusher has fallen down and is
dangling below the hole! No telling how long it may
have been there. I can only hope it hasn't caused
them to abandon the nest.
Meanwhile, a baby (maybe more?) is in the rotten
hole up above the nice new one I kept hoping
they'd nest in.
26 May
1900. Set ambush at the crummy hole. And yes, the
nest is empty - operator error.
27 May
2000. A successful ambush tonight in the new
hole above the exclosure: 3 NOBATA juvs!
4 July
1330. Banded the 2 kids in the 2nd nest (same hole), 2914-2915.
22 August
In the process of setting ambushed (we apparently missed
1 or 2 more kids from the 1st nest) it turns out there's
