Roford 1955 Gynomyx ludovicianus February 21 Nr. Ft. Collins, Colo. mound. Two of E. group had come out & walked a yard or two on crusty snow, breaking three prints in an inch. Most traps buried. One set almost covered in burrow had been walked over without spring- ig, apparently. 11 07 10, kept in cage, healthy but eats little. Kept in house or a book pack. Not too easy to hibernate. Climbed out of 16" deep box quickly by jumping up at corner & getting forelegs over. When wire put over it jumped up & butted with head forcefully. Makes no sounds. Still easily frightened. Near weasel-like odor on occasions. 11 Cold 5 wind. Revisited Spring Dam colony 3 p.m. More activity had occurred during day tho in 20° F. Two burrows plugged with snow back 3" deep 3" wide hole dug in snow at outside of plug. Tracks up to 100' between burrows. One which has small hole poked up thru snow plug at 9:30 a.m., now completely opened & tracks outside. Two that had many tracks on last warm day showed no activity. About 3/4 of those seen to be used on warm day were opened. February 22, 1955 Partly overcast though near freezing all day. At about 1 p.m. I saw 5 out at Spring Dam colony. One taken in still trap (07 11). This same burrow as 07 9 or 10 taken Feb. 16. Ly. broken by still trap. Damage much crawly, cat-like, It butted more into side many times, making smart bloody. Killed this one in lab 4 days-
