Melanerpes formicivorus
Plaque
14 April Watching here 0710. Whoa, another long trip up
over Adobe Hill by I think 8473 following 9494, what's
about 0745 more, I walk over to the Buckeye canyon hole free and
flush a bird out. Don't know who it was, but it
looked like it flew back to Plaque by itself. These
guys need more watching.
1320, I walk back to the Buckeye canyon hole, and
I am greeted by the sight of a 8 woodpecker looking out.
Oh, woe is me!
1430, Not good at all. I peep in, find
a single fresh egg. Almost certainly laid
this morning. Measured (26.3 x 19.1 mm),
marked #1, and returned. Set up blind, and start
watch. End 1500, M. Peacocks.
Start watching near cabin 1750. 1803, 3 birds
in 20 tree, 9496 flies in from cabin BO, pre-cops,
8473 flies over. She mounts, he then makes weak attempt
to mount her, but doesn't.
1808 All 4 birds fly down toward Y area. Very interesting
both 8473 + 8521 are following 9494. 9496 is
following them! I get the distinct impression that 9496
is simply not ready to lay eggs yet, and that 9494 is the
only "receptive" 8.
1810, all 4 have flown to the Y, don't return. 8521
+ 9496 may have drifted back here early, but
I saw very little at roosting. One bird may have been
scared out of roosting in the nest hole by Byron (see his notes)
