Ribbcs, D.O. 1988 Peromyscus californicus 28 Staing Reservation, Mokelum Co., Calif. June 27 checking traps and put her with her pups in a plastic (cage) in the lab around 1000h. Both pups look like 076, and weighed 3.73 and 3.75g. The smaller one had been eaten on, presumably by #1142. The skin from his rostrum ~ 2ml posterior had been chewed removed (chewed off). He was still alive and squeaking loudly so I left him in the cage. The female showed no interest in caring for the pups - she seems nervous. Later in the day (~1400h) I checked on them and the female was still not nursing the pups (both still alive). I can't release her until she starts nursing them. June 28 #1375 ♀ linn, mully. 20.5g. Ear-tagged. RC drift trap, St. E-10. Tissues No sign of any powder, but this is probably offspring of ♀#1343 (early) This and/or DC I dusted ♀ #1343 with BLUE-GREEN powder at st E-10; redusted ♂#1137 with ORANGE powder at station 5,10; and caught ♂#0400 (1191) covered with PURPLE powder (from ♀#1142). OB80h - found one of the pups of #1142 dead with his rostrum and anterior cranial gore. Saved him in cryovial and froze him (Cat #882). Fortunately the female seems to be nursing the other pup, so maybe we can release her tonight. This PM on GRID DC I caught the following animals covered with ORANGE powder (from #1137) ♀ #1359, ♂#1307, ♂#1152. Also I also dusted ♀#1142, anesthetized her, and released her in the nest at station 5,14 June 29 This am on RC ORANGE powder was visible in the ears of ♂#13209; and RED powder was visible in the ears of 1955
