Ribble, D.O. 1988 Peregrinus Californicus Plastings Natural History Reservation, Mariposa Co., Calif. April 23 (Cont.) This PM we # radio-collared the following mice: #1142 - F.M., post-lactating, 40g. Ch#7. Dusted Golden Brown 1181 O? M., scrotal , 37g. Ch#10. Faint Purple visible in ears April 24 1137 F. M., post-lact (normal), 48g. Ch#5. Dusted Orange #1237 F. M., nullip, 19.5g. Ear-tagged. Gprd 2c, St. 5,8. Bloodier, saliva, coil. No sign of any powder, but based on locality this mouse is probably offspring of 1137. White tail tip 1240 F. Mat. pregnant. 44g. Ear-tagged. Gprd WR, St 4,3. Saliva, coil. White tail tip April 25 1241 O? M., TVD. 25.5g "-". "", St. 11,9. "" " 1242 O? SAD, TVD. 25.5 "-" "", St 1,2. "" " Last night around midnight I caught #1232 at station 9,17 covered with RED Powder, thus she is probably offspring of #1174 April 26 This AM while doing telemetry, a strange movement by #1142 was recorded. At 0550h she was not near 16/14 where she had been most of the evening. I went to later check drift fence tags, and when I returned at 0830h she was at the most side of #1979, St. 9,17. By itself this is not so unusual, but she did the exact same thing the previous morning (see Telemetry Data) Then, later in the AM around 1000h #1142 is back at her normal front side. Weird. These two females are not closely related as best I know. This am we changed the collar of #1137 to Ch#7 (her original radio had a hole in it & was not working). Her testes are very swollen, but no milk is expressed. Also, we collared #1955, O?, scrotal, Ch#10. He was covered with RED Powder so is presumably the mate of 1174. Both of these animals were released around 1045h this AM (took photos of #1137).
