Melanerpes formicivorus
1500
22Aug A quick pass here 1230, only ♂297 or /yellow-Dgreen-ad
L6rn/Yellow
in evidence. See Blom1 notes from 20 Aug.
1Sept Looking here 1600. It looks like 4 birds are around now.
L6rn/Yellow
Definitely ♀601 metal/white-green, ♂297 or/yellow-Dgreen and
J676, starting to look very much like a ♂ (DBlue-wht/Bix-wht)
also, the 4th bird may have been J675 Grn-wht/Dan
14Sept I see 4 birds in the BlueOak knoll tree, one of which was
DBlue-wht/Blk-white
which was at the Blom cattle pond
moments earlier. 0806. Also at the Blomone knoll,
→ J677 m/DBlue-yellow (N)
in ♂ plumage!
30Sept Watch r granary census here, 1100-1300 data on reverse,
Well, more changes. ♂297 + ♀601 here all right,
but ♂622
Bix-O/Bix
seen at Blom1 on 14 Sept,
is back here at 1500! So indeed are Juvs ♂677
m/DBlue-yellow (N)
and Juvs 675
DBlue-wht/Bix-wht
both apparently starting to
molt into ♀ plumage! Maybe I've been jumping
the gun about sexing juvs this year.
Storing has begun! I saw ♂622 store 3
acorns, but no one else. Obviously, not in earnest yet.
There seems to be a bit of intergroup tension,
but for the most part ♀601 looks remarkably tolerant
of the 2 ♀ (?) Juvis. All 3 were seen on a branch together,
and though I did see ♀601 give one of the 2 Juvs a mild
peck, it certainly didn't look serious
This means only Juv 678 not accounted for. Is he
dead, or still hanging around Blomone or Blom2
