Sept 4 Brennan Mtn, 3700 ft, 4 mi NW Willow Creek, Humboldt Co, Calif.
This morning while hunting on the S side of
the ridge west from the peak, I gave a
series of Pygmy Owl calls and got a
response from an owl down in the timber
to the S. As long as I gave the single
note, I got a steady response, but
each time I gave the rapidly repeated
note the bird became silent. It took
5 to 15 minutes of steady calling with
a single, spaced note to get a reply after
each time I did that. Finally, after
about 2 hours of "conversation" I gave
two series of rapidly repeated notes, and
was not able to get a sound out of the
owl afterwards. Last night I called an
owl up into the trees overhead, and
had it there for our 15 minutes. I
saw it only once, and then it was in
flight from one tree to the other, high
above me. When this bird first came in
it very excited gave a several series
of these rapidly repeated calls. I wonder if
it is not a territory warning call,
or something of the sort.
Summary- Northwest Coast Transect, Calif.- None of these
owls were encountered on the coast, I was
heard at least 1 night at French Camp, but
