P.A. Kelly 1987 Oct 30 (cont.) 2200 PST. Muffled up I went out to check the 23 pairs of traps - (in shelter) set at Hze 26-76. Nothing at 68, 69, 71, 73 & 76. Very bright but overcast too, bit'4 Moon up in Southern Sky. Also heard a group of pigs foraging and squealing downcreek (maybe Pearson Field or under oaks near Hze 180 C). Decided to pack it in and come out early and bring the rifle for the pigs. Sat. Oct.31 0420 PST Started checking traps again. No sign of any pigs however. Caught 13 woodrats (6 ?: 7 ?) in all and collected all their feces from the bottom of the trap shelter boxes. Ranged in pellet number from 7-110. It occurred to me that I could estimate Neotoma activity if they defecate at a fairly constant rate. First I must find out what that rate is and then I can estimate how long each animal has been in a trap. I also want to use the fecal pellets for dietary analysis. It would be useful to know the passage rate and whether they are coprophagous as well. I caught a new ? (# 1521-22, 223g) at Hze 60; ? 1233 moved upfield from H50 to H26 ; ? 1382-(1523) moved across long field from H.134 to H64; ? 1404-05 moved from H.331 on School Hill to H.136 or lane side of long field.
