Melanerpes formicivorus
Road I
Hastings Reservation
8 September 730. Back on the job! Watching from the hide with Kim
Sullivan, to census, check for nests, and attempt a
vigilance study.
745. 2 birds landed, briefly. ①♀wn/DB/M #383. Stayed to
eat part of an acorn. Apparently no heavy storing here yet;
750. ②♂wn/M #579 in the sycamore by the road.
③♂wn/B/k #580.
820. ④♀DB-w/wn/wn #269; ⑤♀M/DB #804. Eating green acorns;
no storing yet. #269 looks blind in her left eye(!) But
she's still here. She keeps head-cocking to the left a lot
apparently to compensate for it.
830. ⑥♂ -or/wn-or #486.
850. Leaving. Birds are not into storing yet, but are
eating green acorns. Everyone except ♂672 is here,
and he does appear to be gone.

2 February 1545. Counted stores: Valley Oak: 1332? 2702
Sycamore: 1370
This is probably a conservative estimate; both these trees
are loaded with acorns.
6 April! Missy watched here today and saw 3 unbaunted birds
cavorting along with the residents - the only conceivable
explanation for which would seem to be another fall
nest that we missed. Argh. It also, of course,
means that we have a whole slew of new unbaunted birds
to nab.
