Crowder Flat, 5200 ft., 38 mi. NNW of Alturas,
Modoc Co., Calif.
May 24, (cont'd) bird arrives below hole,
squawks. Goes up above hole, down
to it - squawks again - 1st stays in.
2nd flies away. 1st comes out, rests.
11:18 2nd flies directly to hole. 1st
leaves right away - few squawks exchanged,
2nd goes right to work, Steller jays
and Robins calling loudly to (or at) each
other are ignored. 11:48 - 1st returns
to above hole, hitches down. 2nd leaves.
A Red-tailed Hawk soaring over and
screaming is ignored. 12:12 2nd returns
to hole, other still almost all in. 2nd goes
from tree to tree nearby, then away.

although mostly daggti, has a few nuchalis
color traits - extended white stripe on side
of head, a little black on crown. Other
is typical daggetti. 12:13 1st bird out
of hole; 2nd nearby preening, scratching,
shaking. 1st bird leaves hole, flies to
the 2nd bird. Both squawk loudly. 1st
bird leaves - in a moment the 2nd
goes over to the hole. 12:15. I leave.

and the 3/4 nuchalis - 1/4 daggetti bird
flushed from it, alighting a few
feet away and screaming. I used
