K Dixon 1950 Journal May 26. Berkeley, Calif. to Boca Spring, Nevada Co., Calif. I left Berkeley driving the Museum Chevrolet truck at 5:15 accompanied by Bill Salt. We picked up Robert Bailey in Richmond and proceeded via Vallejo, Sacramento and Donner Summit, arriving at Boca at 12:30 PM. We encountered fog until we reached vicinity of Fairfield Solano Co., where I noted Burrowing Owl on pasture fence- post. First seen encountered below Cisco on Yuba River S fork about 6000 feet and last seen about same elevation on E side. We noted Vesper Sparrow on flat covered with Artemisia adjacent to Boca Reservoir. After considerable difficulty with slippery, steep parts of the road we reached Boca Spring, 6000 feet, Nevada Co., Calif. The spring lies on a gentle westerly slope, the west slope of the Carson Range draining into the little Truckee River. The dominant vegetation form is a Jeffrey Pine forest with some openings, the largest in the vicinity being the meadow below the spring. The more open exposed slopes are covered with a sparse growth of knee-high Artemisia tridentata with scattered Purshia shrubs of similar height and the principal herb, Mule ear. (Wyethia). This growth extends into the open pine stands (including scattered ponderosa); in more shaded areas where pine needles have formed a carpet there are scattered procumbent squaw mat (Eriophus ___) now in flower. I hunted through such an area 3:30 - 4:10 PAC DAYLIGHT SAVING TIME. Only bird active at this time was a singing Green tailed Towhee. 6:50-7:50 PM- I hunted in area similar to that of the whole area. I collected a Boggy Nightshaker (T 402) one
