745. Here we are, waiting for some birds.
845. I hear birds way off somewhere, but none is coming
in here; leaving. There are no obvious stores here yet.
1985
12 February
1200. I still don't see birds, but there are lots of stores:
"Main tree": 1066 }
Snag: 1885 }
Doing well!
7 April
1015. Watching from blind.
1036. The tape definitely brings them in. Seen have been
①♂ DB/LB-Dr #123, ②♀ Or-wN/Or-wN #632, ③♂ Yl/M #681, and
♀ Y-LB/LG #916.
1050. As intruders in the lower nest tree are 2 ub 499 and
♀ M / DB
♀ DB-WR(M)/DB ?
1115. Still an occasional intruder and lots of activity here. But
I'm still only seeing the same 4 birds, except for intruders.
They could very well be it.
130. Still lots of action although I haven't turned the tape
on in > ½ hr, but still no sign of anyone besides the 4. Leaving.
1615. None seen in any holes.
23 April
**Group Update**
9779, 9914, 8915. All 3 seen in mid-March 1984,
no more censuses all year! but we will guess
that they left that spring (DA→ May 1984)
but in fact it could have been anytime between
April 1984 and April 1985.
