O. P. PEARSON Mustelinae fuscipes Aug. 12 Set around 2 stick houses east of camp, 3 traps round one and 4 the other, caught a lactating adult and large young at one house and one of other but one trap sprung through after holding very massive. Dr. Miller says he has heard the Mustelina rattling in the bush when he interrupts search crew. Aug 13 A third one today at same nest, this one considerably smaller (and younger?) than the other two. Schuyler seems to have set off one of the Schuylers at another woodrat nest during the afternoon. Aug 14 One young one caught last night before 9 p.m., another large one seemed disturbed by the struggles of the one trapped by my foot and moved away reluctantly when I approached with flashlight, Aug 16 Jack-lighting at 8-9 along road east of camp. Heard several. After much crashing through brush I sat quietly by one nest and a woodrat came within a few feet of me about 2 minutes later. They are so innocent and guileless I don't see how they survive. Also saw one in a nest in attic of abandoned house near south shore of Big Lagoon. Aug 18 Went with Murray to 2 small clumps of small (10") redwoods with woodrat nests in them, the nests made primarily of redwood twigs, one of the nests entirely off the ground in a redwood tree. One Mustelina fuscipes caught in Schuyler in this nest and a Spilogale nearby at another nest. There seems to be a close association between these two.
