Cowder Flat, 5200 ft., 38 mi. NNW of Alturas, Modoc Co., Calif.
June 21 (cont'd.) out in open meadows. No stars visible.
I leave, 8:10. I am almost certain that n> d
visited the nest, and I am positive it did at least
half the time. could d, not too "pure" a d., have
become worn to resemble n> d more closely? I think
not. If both had been feeding, I probably would have
seen both at once as always before. The young in #1
are about 18 days old; it seems that a parent does not
roost on the nest at this stage. N> d went in, then
came out, and d. was not seen in the evening.
Noteworthy at #7 was the fact that there was little
remaining in the nest by any of the parents; it was
mostly feed and leave, or go in, then come right
out. When I write "feed," by the way, I mean
the bird gets his head in the nest—it may be looking
or pushing young aside, but I can't write down all
the probabilities on the spot. When I say "look,"
that means the head is ducked or bobbed in and out
at a rate that seems too fast for feeding.
June 22 - 3:50 at #1—much too dark by nest to see. Moon
still bright. 4:11-4 harsh screams from saps, 5 yds to E of
nest; bird then to nest, several looks or feeds, in, looks out,
back in, then out to asp 5 yds off. More screams. I thought
I heard the young, and if so they are silent again. It is
about as light as at 8:05 last night—too dark to tell
which parent it was. 4:18-n> d looks in, back to 5yds off.
screams. A bird comes from near nest tree, off to W. 4:21.
Tattoos from W, about 30-40 yds away. Sun not yet up.
