Day Canyon San Gabriel Mountains 2 miles E & 3 miles N of Chaffey College of Rancho Cucamonga, the Bernardino Nat'l Forest, San Bernardino Co., Calif. Elev. 2800 ft.
June 25-28 Austin met to set ups by the eucalypts. I caught seven goldfinches today,
(crit) all before 10:30. Because of insecurity about my vehicle & belongings, I am
not putting up specimens here, but I will wait until I get back home.
Weather June 25 was pleasant in the morning, I sighted freezers down Canyon
early giving way to light W. winds by 9 a.m. until 10:30 then increasing steadily
to 10-20 mph by noon and continuing the rest of the day. There were 2 or few
clouds over the San Gabriels, and close to two ones over the San Bernardino Mtn.
in mid & late afternoon. Temp. range about 60°-85°-75°F.
On June 27, I ran the same route as the previous day, except that
two of my sets were on the bajada below the canyon mouth, and two
remained in lower Day Canyon proper. I should have left all the nets
in the Canyon, since all ten birds taken today were from the Canyon,
in which case I might have caught enough birds to complete a point
sample. These birds caught today make 17, all kept alive for data recording
& specimen preparation.
Weather June 27 was just about identical to yesterday, no difference,
really, but I caught sixes, except perhaps a bit fewer clouds noted.
On June 28, I caught the last 3 goldfinches by 06:20. I never even
opened the bajada nets this morning. I packed up my mist nets & poles
and loaded them back to the car, repacked my vehicle and was ready for
the drive home by 08:30.
Weather the morning of June 28 was cool, cloudless & still. The
air was actually a bit dampy. Temps. 60-70°F.
Species List Day Canyon June 25-28:
