RIBBLE, D.O. 1988 Peramysis Californicus 17 Hastings Reservation, Monterey Co., Calif. April 26 #1243 ♂ Wolf, TWD, 43g. Ear-tagged. Trapped ~40m upstream of coll. April 88 (cont) Robertson Creek's Finch Creek Confluence on Robertson Creek. No tissues * #1135 ♀ Wolf, lups, Pamous, 45g - Dustied with Green Powder. We trapped this animal for captivity purposes along the same transect as #1243 above. It was tagged in December 87 east of GRID DC; this represents a minimum dispersal distance of 0.25 mi (by Martin Rd measurement). GREAT! This Pillow PC, Marco removed the radio collars from #0300 and #1917 (definitely lactating). The collar on #0300 had a hole in in the transmitter portion, accounting for its malfunction.

It was very strong and definitely coming from 2 radios (e.g. 2 tone very quick beeps). At that moment there was a distinct rustling in the grass, blackberry 0.5m to the SE of the station. ~30secs later an animal moved ~2m, NW from the station. I removed the cable from the antenna and tried to get a visual on these animals - no luck, but the beeping (both #7's) continued. At 0455 I rushed over to the west monitor cable and #1137 signal was weak for ~10 sec, then very strong. #The male #1152 was also in the nest. Then at 0500h I
