Gymnops californianus
May 11, 1946
Nr. Famoso, Cal.
saw three earlier. "ragged" had no "prop ledge." 10:43, one, &
10:46, the other, disappeared behind a hill as if to land.
10:49, I saw-1, & at 10:51, 2, circling near the burn.
into the group scattered. I passed over me heading
NW at 10:00 (adult). This one had ragged to right
wing (burn), a slot in left side of tail, & short
#4+ left primary. 10:01 a second adult passed 1/4
mile S. of me also gliding SW. 10:03, I saw-3'
still circling 1 1/2 mi. to S.. 10:09, one of the adults
went down about 2 miles to NW of me just be-
yond a burned area. This grass had been burn-
ed since my last visit & was about 6 acres in
extent & located about at the center of the road
"triangle". I saw the passers car on the Porterville
road W. of that area this morning. It seemed each one was
over the burn, & another was about 3/4 mile S. of me.
10:16, I lost the one over burn. 10:18, there were 2
about 1 1/2 miles S. of me, 2 more about 1 1/2 miles to
E., & so 6 total (including 2 at burn). 10:22, I
saw one descend behind a hill about 2 miles to SE of
me (halfway to an oil Derrick). 10:25, saw-1 still
about 1 1/2 miles to E. & watched it - it wandered about
at 100+ altitude, put feet down at 10:31, & descended
as if to alight about 1 mile E. of me. In going
down, flexed wings appear from front
& the turns are much faster & shorter than the
normal "searching" flight. 10:35, I saw one circling
in that vicinity again - it was the "ragged" one
possibly
again. 10:40, I saw 2 there - probably the same as
