Koford 88 Cynomys ludovicianus April 13, 1955. 50 yds. from burrow, gathered grass, took to #4 at 8:09 & down into with lunch of dry grass (4 Kochans?). Other one ran to #3 as occurred on approach- ed. // In area I picked up 5 Agouti to pellets. They contained winter pastur worthly, it appeared. One large coyote (?) dropping found. String of 5± C.L. droppings connected like necklace - due eating long fibrous food? Saw one C.teller 13-linistes in a C.L. burrow mouth on preserve, set 5 live traps in horse pasturing, 3 still traps in preserve. At 6 p.m. took those up. Caught 2 at #3 & kept alive. Two in still traps. Three drilled: One advanced pregnant, lilly & foaled apparently melting. // Jim Lawrence told me he saw one an old poisoned tam near his house (formerly way); he thought this survivor, not new arrived). // At Dec. 22, CPER, colony, from W. end counted 16. At H. intensity, 1 N + 15 of fence at usual site. At least 3 on very flat but gently sloping ground just S. of center straddled in center. One 50' N. of fence, 200 yds. W. of E. fence. Burrows formerly there but this first C.L. One of highest burrows on S. center also had dog. Feeding mostly on lower areas. Now seen outside line of outer burrows. // I set up 10' x 10' explosion at NW end colony just N. of fence. This will be surrounded by 30' x 30' barbed wire cottle explosion. One side of large explosion is fence. Some laid out at S E end colony. // About 4 p.m. I saw 4 in bottom & E. of E. fence. Upon chary, one ran to farthest E. (formerly stabled) burrow. I wounded one 30 yds. E. of E. fence but it got down burrow. (This burrow burrowed for at least 2' about 6" under surface ground). // Now rattled at burrow just S. of bottom & 100' W. of E. fence (table then). The mound of coarse tecture so that formerly I suspected lodger dug it out. Four Antil- capra seen near SNE corner of colony 4:30 p.m. Set 5 still
