South Fork Kern River Wildlife Area 3 miles W of Weldon Kern Co,
California, Elevation 2500 feet.
July 9-11 rained after 11:00 at 5-10 mph out of W. After 14:30 light gusts
(Cont) to 25 mph became common. Temp. Range 55°-85°F.
July 10, I opened my nets 05:35-05:45 and walked to wood-
lands between checking for birds. Setting started slowly, and
I moved two nets further downstream, adjacent to a grassy field
with lots of Helianthus. This was much more successful a setting
for netting goldfinches. Over the course of the morning I caught
7 C. psittacula in my nets and saw several C. lawrencei and 3
C. tristis. This is the first place I have visited that has had
summer occupation by all three. I also caught one C. lawrencei
and sustained two misses and death of one Melospiza melodia (not
came out of snare). The majority of the afternoon and evening I spent
recording and putting up birds, the nets being closed at 14:00.
Western June 10 was similar to yesterday, with temperatures 55°-
85°F in shade, but no clouds were seen all day, and no gusty
winds came up in the afternoon, only the light W. breeze.
June 11 was a frustratingly slow day. I moved the 2 nets
not moved yesterday at 06:30, since few goldfinches seemed to be
in their vicinity. The two nets over the Helianthus field caught
few birds, all non-goldfinches, though dozen goldfinches remained
fairly numerous in the adjacent field. At 2-3 hour intervals,
I hop-sketched pairs of mist net increasing westward, into
younger woodland. In surveying the last half mile of cottonwoods
and willows, I found 5 Yellow-billed Cuckoo, a group completely
unknown to Steve Layman, who is closely following what few birds
he knows of on the S. Fork Kern River. These apparently had
