two Onychomys dens, Our test Oryz. near the tent seems to eat actual watermelon, apple, cheese, & becon - but won't go into traps to get them. Before lunch we built a scrap roofing corral and tow apart the rocks & cacti near the tent - soda. Then another one where we disturbed an onyz from his shredded Ephedra nest under a cactus branch. he ran more control, then to another clump, and we finally caught him by hand along the tin corral, a similar attempt with another mouse, after several mad scrambles, netted a big O phyllotis. 6 cows at lunch moved off the valley onto the grid. March 31 night + morning clear; dawn or cars. Amator live traps had 2 Phl damini, swift traps ha 3 dammini and 2 ammiene. She found a mummy of what looks like alcedors. My grid as follows: Day 4 - E8 - met Onychomys, probably caught during day yesterday and sedated own; still alive but grumpy. XO - another Onychomys / location not recorded.
