Murray 1948 14 Journal Apr 13 Enroute El Mayor Citellus tereticaudus and saw at least one Citellus leucurus. Since I am in the second truck I don't see much beside dust. Apr 13 El Mayor, Rio Hardy, 30-54, Baja California. We camped not far from the road, between the river and the northern end of the Sierra El Mayor. Beside the camp, and all around the branched river is lush green vegetation. Much of it is mesquite. Arriving at 6:30 PM, there was just time to set out 50 live traps on the mountain slopes. Saw 4 American egrete just before we got there, along the river. The mountains are mostly slaty shale with some areas of solid volcanic looking rock. Vegetation is sparse, with creosote and a little of other unidentified bushes. Mosquitos are here! There are also plenty of gnate. Otherwise it is quite pleasant. At dusk we saw numerous Rats, some quite large, but couldn't manage to hit any. Saw a horned owl disappear over the mountain. Earlier heard a cactus wren, Lila woodpecker, ash-throated flycatcher. There is a frog croaking down by the river. a poorwill flew over.
