Abstract
We tried to develop the methods for tracing wild animal's behaviour, especially hare's. This method is to trace hare's behaviour by multiple antennas, which is set in the breeding enclosure. This time, we put an emphasis on finding out the co-relation between two hares' behaviour during a certain time, compared with doing single hare's one in the previous time. We used the following equipments ; two transmitters, 45 multiple antennas, selection level meter, coaxial switch box, micro-computer and printer. Micro-computer is for controlling of the coaxial switch box and selection level meter. We got 14 pieces of tracing locus about two hares' behaviour after 938 times' experiments between 15 : 43 p.m., and 6 : 01 a.m., December 18-19, in 1986 in the breeding enclosure of Niigata University. There is a possibility of finding the hares' behaviour through the tracing data of sitting and feeding activities.
