P.A.Kelly 1988 Journal Thurs 0>1651. The unidentified rat was possibly Mar.10 0>1284 from H.47, he is also the probable (cont.) father of 0>1651. We then tried to do some playback (before returning 0>1651 to H.51). The first on Jeff's Takedeck playback of the juv's squeals resulted in ?1489 coming out of H.51 again. But some repeated playbacks from my smaller Sanso Tape Deck (placed in the entrance to H.51) did not illicit any response. We packed up at 2245 PST. pretty pleased with our evening's work.
