Dec 87 Acorn Count: 7000
1 April 0800 2 birds at 87 hole (8) 3rd came out soon after.
6 Apr 0845 Put up new string, then climbed. They've
Filled much of this cavernous hole with acorns!
Mustive done it in the Fall. Anyway, they're all
sprouting - the birds are making a new entrance
into the hole as well. This hole was just
above the new "Floor" level, so I cleaned
out some of the acorns so eggs wouldn't roll
out. Not much of a laying surface. On the limb
near the nest I Found white eggshell Fragments. 4(0)?
Tossing? No birds in nest on arrival.
19 Apr 0730-0930 I break my own rule about cutting open holes
early - I assumed they'd be Finished laying by 18 Apr.
Well, maybe they were - there are 8 fresh cool eggs -
but had I waited 'til late morning maybe there would
be 10. It was a time consuming climb r cut. (And a
not very waterproof one - I hope they survived 19 Apr)
27 Apr 0640 Driving by I see that the door has Fallen out and
no one responded to my hello. Damn, I guess they Failed.
No! 0830 I see a bird at the hole, I bite the bullet, Find
the door, duct tape it up, climb the tree and replace it.
They're hatching! One egg is gone, one infertile (removed)
:: 8-1-1 = 6 viable eggs, 2 of which have hatched.
RL = 4.2, LL = 4.0 (Time 0900)
