12 Jan ** GROUP UPDATE **
① Purge J674, not seen after banding
7 May I wander around all over the place up here, but find
no suitable holes. Also Alan watched up
here recently and saw 9674! D-9 plunge!
See his notes for details.
17 May Well, it takes a while, but I finally find the nest up
here. It's a huge decaying old Blue Oak, ~100
meters SE of the granary. Though the tree is quite
dead, its pretty solid, and I was able to climb up
without too much trouble. Since I didn't bring climbing
gear, I'll have to come up later, to open the hole.
The eggs have hatched, but adults are still brooding.
Also, while I was watching I actually got a complete
census. 9531 Brn-or/Brn-dr
⑤530 Brn-or/Brn-or,
a-d 9674 Dbrn-Red(N)/or all seen quite well, all seen
carrying insects or acorn bits off toward the nest.
18 May Opened the nest here, 1745: Found 4 babies, ~12 days
old. Three look quite healthy and should fledge.
⑤ A 4th is definitely on the runt side, and may or may
not make it. That means I should band this
group on 28 May
28 May Banded 4 babies, and bled all but the runt 1500.
Now J756-759. The runt was quite tiny,
but seemed vigorous. He weighed only 35 grams.
18 June ** GROUP UPDATE **
① UNPURGE J674. alive + well
