22 February
1445. Counted stores: Main tree: 968
Other: 45
1213.
Not bad. I'd put capacity at 1200.
11 April
1020. At least 2 birds were around last year's nest hole, so I went up and opened it, finding some moss and the makings of a mouse nest (but no mouse). I cleared it out, and with luck maybe they'll still use it.
17 April
1700. Looks like I'm in luck - there's a bird in the hole now. These birds also have stores remaining.
22 April
○ 1039 intruding at LA2. See LA2 notes.
1330. None in the hole (last year's nest): it's empty (but is in good shape now).
7 May
1415. Watching for a nest. ○♂ Red #736 here.
1450. Now 2 ○♂, second ○♂ /m #1039.
1545. Found the hole - it's in the same tree as last year, but in the hole above the opened one! They have babies ≥ 14 days old; should be opened soon.
8 May
1100. 4 Babies in the nest, ~14-15 days old.
15 May
1300. When I was up here before an ominous crack opened up in the limb, which I nailed up, but, as it turns out, futilely. The entire limb fell, taking the babies and both nest holes with it. A double tragedy!
16 June
1600. Watching.
1630 ○♂ or -? /m #1037. ○♂ -bp/red #1039. ○♂ m/b-w(m) #736
1645. ♀ here also, but haven't seen her legs yet.
1655. Going to look for a nest.
16 September
845. Watching. Lots of new acorns here now.
