1987 Spring Creek Pass, elev. 11,100 ft., San Juan Mts., Hinsdale Co., Colorado
June 7 A good series of trilling calls from
(cont'd) this juvenile has been recorded.
I captured the juvenile by hand
and killed it for the specimen.
I drove into Lake City again
today to call home. I got there
late in the afternoon. It was
cloudy and drizzling, and by the
time I made the phone call it
was raining.
I returned to Spring Creek Pass
after the call. I camped further
up the road, at about 11,200 ft
at the edge of a clearing/meadow.
June 8 I set up a net near a patch
of snow and a dead tree in
the southern edge of the meadow.
No luck at first, but then by
a great bit of good fortune I
cought a type 5 male (did not see
him get captured). Not long after,
(maybe 1/2 hour) a lone ? Type 5
came in and was only interested
in 569. She (#571) had an
active brood patch and ovary,
so I wonder if she was 569's
mate [see sonogram for call-matching
