Melanerpes formicivorus
Central Canyon HNHR
1 May
This group was discovered a week or so ago when
Mark and Shorty saw a bird going in a hole in the dead
Valley Oak up the Central Canyon. Sure enough, they
had babies (3), about 12 days old today. Other important
features: The birds are unbanded, hence not laguna,
and they have some acorns stored in the bank of the tree,
hence they've been there all winter (!)
In any case, this evening I went and caught a ♀
at the nest, so now someone here, at least, is banded.
Watching a bit, they (2 only) seem to fly up over to
the Hastings side of Blonkoll, hence they don't appear
to be Refule 1 birds either. Amazing!
7 May
Tried to catch the ♂ for about an hour this afternoon, but
only the ♀ I caught on the 1st fed. However, she'd fly
off a couple of times to the 2nd canyon, so it's possible
that these may be birds we originally (= last fall)
called Refule 1 birds after all.

1030. Set up to try for the ♂ again.
1230. The ♂ (I think only 1) came several times, but the
birds don't tend to go in anymore, or they stay only a very
short time. I'll try ambushing in the morning.
9 May
500. Got him! He's now ♂1523. I also banded the babies
as #1524-1526, and then put them all back in the hole (blocking
it up for 5 min) before releasing The ♂.
Most likely, this is everyone in this group (it's just a pair).

I'm going to assume that the putative "Refule 1" birds were this
