Journal 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
