Melanerpes formicivorus
Blom one - Blom 2
(20 Aug) Plus, shitload of 1500 birds. ♂622 BIR-Or/BIR J676
DBlue-wht/BIR-wht
Wht-DBlue/m (very prevalent!) J675 "" / DGreen-
(Seen occasionally, "dirty" face) J678 metal/mauve, all ove-
on the big knoll continuously (more or less) from 0800-
1000. All were eating green acorns, especially from the
Big Live Oak that dominates the top of the knoll. I
got the impression that ♂492 ad 9649 would fly over to the
Bll granary occasionally, but the other birds seemed to be on the
knoll most of the time. I saw ♀649 chase J676 once, but
I never certainly saw ♂492 chase anybody but the unbanded
birds. I never certainly saw ♂492 chase ♂622 or any of the
Jaus. Where these birds will wind up is a mystery to me.
Also, ♂493 CBlue/CBlue put in a brief appearance on the knoll,
but I saw him fly in from the direction of Blom 2, harvest
an acorn, then fly back toward Blom 2. I'd say he is
still in residence there.
Down watching Blom 2 at 1030, 3 birds in the granary (nest
tree) when I arrive, including a ♀ I believe. Later, I find
M / DBlue-Yellow (N?)
none other than J677 DBlue-Yellow (N)/DBlue the last of the
1500 Juvs, in the Blom 2 nest tree. Also J678 there briefly,
ad even J676 cruised into the nearly dead blue oak for a few seconds.
1100, ♂493 here in the nest tree, as suspected. 1150, Just had ♂
493 ♀478 M / DBLue-Or/DBlue-Or
J678, J677, all * in the nearly
death Blue Oak perch tree. Everybody looked happy, to boot.
♂493 + J678 may also have been sapsucking from the Valley
Oak 10m west of the Laguna Conejo dam, but I wasn't positive.
So it looks to me like Blom 2 is a real, live group! How
