Melanerpes formicivorus
LA 2
7 April Start watching here 1330, ♀637 CPK/BTK ♂846 NB
plus a 3rd male (presumably ♂611) here. 1345, ♀637
chases out a ♀NB intruder. 1355, ♂611 Blue-wart/Community
here too. Good. Weird group still intact.
14 may Watching here 1500 ♂611
CPK/Black
here for sure. Probably the third bird, ♂846
NB present as well. They still have a very few acorns
remaining in the Blue Oak granary (~35). Doesn't look
like ♂(♂?) are tightly packed with ♀. 1600
17 may Start 1115. ♀637 CPK/BTK and at least 1 ♂ here flycatching
from the big Valley Oak. ♀637 left alone for a long
period, suggest: ① Not ready to nest ② already have
Metal/
a nest ③ only 1 ♂ here. 1200, ♀637 and ♂611 Blue-wart/Community
here all the time. No evidence of a 3rd bird at
least as far as I could tell. Perhaps LA2 is down to a
couple. As far as nesting goes ① The back hole currently
appears to be occupied by nesting Bluebirds. ② I saw ♂611
and ♀637 take a long hard look at a hole in the top
of a broken stub of a Golden Oak near the bottom of South
ravine. Fortunately, neither bird went in. Hope they don't
nest there. ③ A large Black Oak just west of the previous
tree might be worth looking at for hole possibilities.

These guys have pulled a fast one. After
watching here awhile, I see ♀637 fly into the low hole of
the granary. I flush her out, climb up to the hole,
and find 3 just hatched nestlings and One egg that
has a chance of hatching as well. Too bad. Considering
