Melanerpes formicivorus
1900 Hastings Reservation
6 January
1315. Nobody here.
1330. Some calling now. ①♂LB #43 in main tree eating an acorn.
1335. ♀ peacefully in main tree - ♂ was dark (#166?).
1337. ②♀my res #191 landed in nest tree, causing ♂43 to fly over
there and another bird (I think) to karit-cut violently.
1340. ♀191 now preening in main tree; at least one other ♀ here.
1343. Displacement at top of main tree involving ♀191 and 2nd ♀.
1345. ③♀WN/DBlue #260 here after all (!) She obviously is
playing both sides of the knoll here.
That seems to be about it. I don't see ♀193 here today.
12 January
1320. Watching. 1♀ in main tree.
1328. ①♂LB/WN #43 in main tree. The ♀ appears to be ♀WN/DB#260,
and seems to be the only one here at the moment.
1350. ②♀260. Still no other ♀♀.
1355. It would appear that these are the only 2 girls
hanging out down here ♀ at the moment. (!)
17 January
930. Counted stores: Nest tree: 30 }
Main tree 269 } 299
3 birds responded when the ♂ began karit-cutting at my
presence below the main tree; among the 4, one immediately
tried to displace one of the others, much as was happening
among [the same?] 4 birds here on 6 January. Also, at one
point I watched a bird fly from the main tree here directly
to tree 1 at 1500 [presumably ♀260.] Obviously things are
still not completely sorted out here as yet.
18 January Took 30 acorns from the main tree, replacing them with some
good Valley Oak acorns.
