Estuar, Fri 1960 Journal 11 April Pinto Basin, 1,750 ft., Riverside Co., Calif. We found a black-throated Sparrow nest with 4 light blue eggs. The nest was about 8-10" up in a shrub Burrobush (? Franseria dumosa Gray) under the N. Canopy of a Larea - on top of the dune area. The shrub branches formed a complete canopy to the nest which was perhaps centered from the S, thru the Larea. The hole was 4"+ deep and 3 1/2 +- wide. The Larea did not form an essential part of nest support. It was photographed. Back to Camp. Out of camp at 3:00 p.m. - at 29 Palms by 4:00 - shopping, etc. & 5 on entrance road, thru the monument to Joshua Tree & on to Indian Cove - same camp area as first night. Windy cold evening. The cloud pour moved past to NE. 12 April) up and out to 29 Palms & on down to Pinto Basin where we stopped at the gravel pit and went into the dunes to collect; at 3: p.m. we went to Cottonwood Springs and beds - a quick meal and we read the roads for herps: one Diposaurus, many Dipodomys and Sceloparthus until the low moon came up, then rodent activity slowed greatly.
