Murray 1948 Journal July 10 10 mi SE Mesquitale, 400± ft., Baja Calif. in a dead trunk. After being frightened back into it, the creature later popped out of still a different hole in the ground a few feet away. Both times it practically had its hind legs hanging down the holes. The trunk to be sure was hollow and undoubtedly entered from underground. Another squirrel, watched from a distance, entered its hole and soon came back out; stood high on its hind legs rather than just sitting up to watch me. Scared it back to a position half protruding from the hole, where it was soon joined by another from a hole a few inches away. These eventually both came out and disappeared behind bushes. Both were adults. A large proportion of the squirrels are young, however. Altogether shot 2φ adults, both lactating. Three different times a night hawk flew by; the last must have been at least 9:30 and pretty bright and hot. Saw a pair of purple martins chasing each other. One new bird for today was a Bewick wren. Many times in the past few days a lizard has rushed down the trunk
