Melanerpes formicivorus
Hastings Reservation, Monterey Co, Calif
(2 February)
1700. At least 2 birds are along Robertson Creek between
the Gate and the Mellin Ranch road (about ¾ way or more
Towards the [illegible]). One, calling a lot, was a banded ♂,
but I could only see a L.Blue band on the lower left. I
have no idea who he might be.
12 February
1400. Pam and I walked up Prison Oak Ridge. Once again
there was an unusual amount of activity at the territory
Where the Thanksgiving Revolution was. Though not on the
order of a full-scale revolution, there was a fair amount of
chasing, fighting, lots of displaying, and so on; all in all
it seems amazing that these birds still don't have their
differences settled after nearly 3 months.
1500. Action has picked up. About 15-20 birds [illegible] involved.
Lots are banded from November: ①♀316, ②♂325, ③♀327, ④♀329,
⑤♂330, ⑥♀332, ⑦♂334, ⑧♀337, and ⑨♀342. ♀316 was doing
a lot of the chasing herself, acting as though she belonged
here. In addition, there are several (5?) unbanded birds, all
of whom so far seem to be ♀♀.
1600. As before. A fair amount of chasing, etc. going on.
18 March
1345. I returned to Robertson Creek, the area where
I'd seen the birds on 2 February. Very close to the area
I again saw 2 birds, and managed to observe set length
the ♂, who was indeed banded, and after ½ an hour of close
watching identified as M/LBlue DBlue/LBlue #323, the ♂ from
MacRoberts! There are no granaries here (that I could see)
so presumably he and the ♀ moved here when their stores at
MacRoberts ran out and are trying to make it here on
