Melanerpes formicivorus
Blom one
14 Sept
Well we do indeed have a threesome at Blomone. Watching the
granary at 0815 I spot ♀649 white/DBlue and old ♂623
Black/Or-black back and looking like a member is good
standing. Plus a third bird (♂) which must certainly be
♂492, though I didn't see bands. Birds shuttling back and
forth between the big knoll and the granary. No evidence of
any of the current 1500 Juveniles hanging around the granary,
but I need to check the knoll area.
0930: Great stuff. On the knoll, in the VO's on the
north side, I find 1500 J♂677 M/Dblue-Yellow (N) / DBlue
actually defending a small area around a small, mistletoe capped
VO. I even saw him chase 2-3 times ♂623 his older brother who helped raise J♂677! What a punk!
I guess this says something about site-related dominance.
♂677 seems pretty serious. Also saw him chasing a ♂NB.
Very strange: there are, of course, a very few storage
limbs up here on the knoll. And there are a lot of acorns up
here. So who knows?
1 Oct
A quick walk by ♀649
wht/DBlue These birds (now just 2?)
have started storing! About 30 or so new acorns in the granary
** 6 Oct Group update: ①♀648 is clearly gone, almost certainly
returning to her natal territory (wherever it might be), with
rejoining ♀650. ♀648 last seen on [illegible], June
and I think certainly absent by 8 June, so say
♀648 left group about 5 June ± 0.
② ♂493 moved Blom 2 14 July ±2weeks: Last
seen certainly at Blom one 25 June, but was visiting
