Melanerpes formicivorus
Arnold 3
Hastings Reservation
(31 May) fence line; identified were ①♂ub, ②♂LB/M #205(!), and ③♀ignav/or#289;
a 2nd♀ was here also. They were hawking and seemed to be going
to a large thicket on the other side of the fence, which I'm going
to check out.
1155. Watching from hide. I can't believe there's not a nest
here somewhere or other.
1325. Have been following several birds, who have been going all
over with no obvious bias. In the process, I identified
①♂Red-w/blk-la #120 and ②♂wn/#125, who were both in/near the
granary for several minutes. For now, I'm going to explore
the canyon for a while (around South Ravine) and look for
any promising holes. If not I'll have to try again soon,
I returned at dusk to see what I could from roosting.
Birds definitely did roost in 2 holes in the tall Valley Oak by
the fence line, and at least 1 bird went in a strange
down-hanging knothole in the '75-'76 nest tree, but none
roosted in the old nest hole best I could tell.
1 June
2000. 2 birds flushed from the hole in the broken off limb
of the Valley Oak next to the granary! Keep your fingers crossed.
5 June
1530. Nobody seen in any of the holes here.
7 June
1100. This time, a bird was in the hole in the broken off limb in
the Valley Oak again, so I opened it to find 4 fresh eggs!
Finalement!
11 June
1530. Bird in the hole.
12 June
1800. Bird in the hole. Hole opened; still the same 4 eggs, all
opaque and incubated.
13 June
1130. Watching from hide. Bird in nesthole.
