RIBBLE, D.O. 1988 PERDIX CALIFORNICUS 19 Hastings Reservation, Monterey Co., Calif. May 4 This am #1 removed radio from #1155, 8", scrotal, 39g; he was covered with fresh RED powder, 2) captured #1142 without her collar; dusted her with GOLDEN BROWN. (7:00) This afternoon I located the collar that was on #1142. By using a wire stuck in the antenna slot on the receiver I localized the signal to the base of a Salix at ~5.3, 13.5. The tree is leaning, ~15cm dbh, hollow in the middle with gaps holes into the middle starting ~50cm from ground level. This is the same site Marco located #1128 in Aug 77. There is no way to reach down into the tree, so tomorrow I will try and core into the tree to retrieve the collar. This PM Lauren and I did the following: 1) Chocled the Salix at station 5.3, 15 for powder- GOLDEN BROWN from #1142 toate very obvious inside hollows, 2) caught #1231 with RED powder visible in ears, 3) #1217 covered with GOLDEN BROWN powder, 4) removed the radio-collar from #1152, 8", 39.5g, scrotal (collar in good shape) and 5) got a very weak signal from #1137 at 7.9.- no clear beep, only a muffled rhythmic beat, perhaps the battery is wearing down. May 5 Removed the radio-collar from #1137 this am at station 7.9 (Ch#7). She wasnt lactating, but her teats are very swollen and she is definitely pregnant (52g). Dusted her with DEWEY'S powder before releasing #1264 8" Mature, scrotal. 38g. Ear-tagged. Geld RC, St 7/9. Blood, ear, saliva coll. 1265 8" Lake SAD, TWD. 37g. " - " 1800- This afternoon Mark Stanback cut a wedge out of the base of the Salix where #1142 lost her collar. The wedge (wrenlow) was about 10x5cm, about 25cm above ground level. It was a perfect cut, opening at the top of a raven's nest which is obviously being kept up. The radio-collar was sitting in the bottom of the bowl of the nest.
