S. v. daggetti
Crowder Flat. 5200 ft., 38 mi. NNW of Alturas, Modoc Co. Calif.
June 22 (cont'd.) 10 in in diameter, living, with several other
holes in it. I was attracted to it by the now-familiar
cries of sapsucker young of over 10 days old. A bird
came up and screamed at me - it was a d. with food.
I went on so as not to disturb them unduly or attract
predators. This is nest #11; how I missed it until
now I don't know. I remember tapping on that tree
and getting no response about 2 wks ago, when the
eggs were unhatched, I guess. I continued to pace off
toward #8. This nest, by the way, is too difficult to
watch for any length of time as the only place it can
be clearly seen is so close that the parent birds are
obviously distressed. #8 is about 400 yds N. of the new
#11; possibly there are one or two nests between,
as there are some suitable asp, but I heard no more young
on this rapid jaunt. The meadow clears of trees a bit,
and it is about 350 yds to #1. As I passed I heard
the young and saw a parent feed them in the nest. I went
on and came out to the asps on the SW edge of the meadow
about 100 yds SW of the ranger station. Here I heard young
again, and located a nest, #12, in a big dead pine a few
yards west of the aspens. A typical daggetti fed, then
went in. This tree is about 45 ft. high, broken off sharply
at the top, and dead. Like #10, however, the bark is
still on it. A couple of feet down from the top is the nest;
there are several other holes around it. The nest faces N.
The nests are easy to find now that the young are so noisy.
I can now draw a fair map of the nests in the area.
