Day Canyon, San Gabriel Mountains, 2 miles E & 3 miles N. of Chaffey College of Rancho Cucamonga, San Bernardino Nat'l Forest, San Bernardino Ca., Calif. Elevation 2800 ft.
June 25-28 Hours sleeping in my car at a roadside near a few miles E. of Ehren (exit) Burg, Arizona. I then continued W. on I-10 to Interstate 15 north to the Forties Bends exit, W. to Etiwanda Ave., N. on Etiwanda to the gravel roads and arches gate below Day Canyon. I arrived at 10:45 PDT, June 25, pretty good time, though I benefitted from crossing two time zone boundaries. I have only a few days left on my collecting permit for California, and I still need birds from the far south part of the state. I worked up toward Day Canyon and found that Green goldfinches are really numerous here, even about the sage scrub below the canyon proper. They are quite common about the mouth of the canyon. I set up with my nets and carry cages. By 14:45 I had all 4 nets set up for the afternoon.
The Resitil was described on a visit this past April, & Jim deJauries. The only significant difference is that the green, then green, is now from & dry. Because the area around the locks got it used as a target range, I did not camp in the canyon, but stayed with my vehicle during the night and I hiked out at least twice during the day to check on my stuff. I caught our goldfinches June 25. I moved my nets late in the afternoon to sites that would be shaded from the morning sun.
Weather June 25 in the afternoon was clear and windy, & W. winds 10-20 mph, perhaps a bit higher away from the relative protection of the canyon. Temperature 85°-75°F.
On June 26, I hiked up into the dark and opened my nets as it was just getting light. When I walked back down to check on my car, I noted that goldfinches were perfectly numerous around the saguaro so weren't trying to mist net birds down there. In my mid-afternoon car check, I brought down one net to set up near the pine grove, and at sunset I brought out another net to set up near the pines.
