→ Disappeared about 27 March 1976 ± 2 weeks.
845. Watching from "hide." ①♂RRR#236 here.
945. Several birds here w/o: ②♂1971 eating acorn;
③j309; ④j307; ⑤♀172 eating acorns; ⑥♂173; ⑦j310 fed by ♂173;
⑧♀ub; at 1003 most have gone off down into the canyon.
1100. ⑦♀R-w-B/wn#170 feeding j309 acorns.
1125. Several birds back finally; j309 is getting the shit beat
out of him by ♂173 at a snag where he and j307 were making
[illegible] nuisances of themselves.
1128. j309 pecked at and tore off j307 while begging at ♂236.
1145. Enough of this. I'm going to jaunt down the canyon to
see if I can find out what they're doing there.
✓ 28 July
20 August
Counted stores: 487. j310 in telephone pole when I arrived.
Heard lots of calling over here while at H-Blom.
1300. Began watching. Birds are all over, except there
is not much activity on the knoll. Apparently, however, the
reason is merely the activity involved in hawking, which is
primarily what they seem to be doing; I saw no chases at
least up to 1330. I did see all 4 juveniles (307-310),
②236, ⑥♀ub, ④♀170. [It occurs to me to mention that the right
tarsus of the ♂ub was slightly swollen and quite yellowish,
the same characters noted in the ♂ub ♀ here since the
spring of 1975].
1340. ⑧♂LBRW and ④♂WLLW here now also. Still lots of
waking, hawking, but no chasing.
1345. Everyone's still hawking feverishly; jwus are hawking and
doing some begging from hawking adults. A ♂ with no wing-streamer
