PEARSON 1951-1952 January 3rd. from at least some features, but lots of old dragings 20 yards out. One large clump of feature all by itself had fresh dragings under it and 2 trails of dragings radiating. There are certainly more features within 50 yds of "standing" vegetation than out in the desert. Concerning voices, they occasionally make a sound somewhat like the flutter of a small-bird's wings. This is an alarm call made as they disappear down their burrow, not events to appear Jan 16. At my watching rock in the morning 5 fresh dragings were visible and 3 twoes were dragging at the same time. The closest one dug for about an hour and only took a couple of lutes to eat during this time - these from the unworked side of the hole. At the close of digging she did a little more feeding from this side of the hole. She dug up small pellets by scratching with the front feet and burying, then carried them down the hole in her mouth to eat. She did practically no eating above ground. After activity had apparently stopped I left and came back in a half hour. She had then done a small amount of digging at the holes of 3+4 days ago and was doing more feeding, less dragging than before. I think the new dragings are not primarily for feeding, at least not immediately. The brushers on the hind toes are used for cleaning mud off of the posterior ventral fur (lower belly). This region gets quite dirty from dragging. Twice I saw the close & scratch this region, using one hind foot at a time dog-fashion. Only 2 new dragings on the census-area, one at 9 and one at 11. Set traps at them and at 10:30 caught a ? at 11
