Comparison and Change of the Observation time in eight Animals by theZoo Visitors
Yoshihide Takaki Kooji Hayashi

Abstract Comparison and change of the observation time in eight animals by the zoo visitors wereinvestigated in Fukuoka City Zoo from 2012 to 2019. In all years, the average observation time in theJapanese monkey is the longest, and subsequentlly those in the giraffe, the otter, the elephant and thepenguins were long. The average observation time in the lion and the leopard tended to be shorter, andthat in the fox & raccoon dog was the shortest. It was suggested from the behavior of zoo visitors thatthe variety of behavior, livingness of animals and spatial easiness in observation influenced the lengthof observation time. Although the significant changes between years in the Japanese monkey and theelephant were seen, there were no significant changes of observation time in other animals. In theleopard, observation time might get longer by an event such as the baby birth, but the influence toobservation time by the behavioral exhibition was not seen so as to have expected it. To enjoy a zoo
by observing animals slowly and carefully, the cooperation of zoo and visitors will be necessary witheach ingenuties of them.

Key words: zoo visitors, observation time, behavior of zoo visitors, behavior of animals,
easiness in observation㸯㸬ࡣࡌࡵ࡟ᗂ⛶ᅬᩍ⫱せ㡿ࡸಖ⫱ᡤಖ⫱ᣦ㔪ࠊᗂಖ㐃ᦠᆺㄆᐃࡇ࡝ࡶᅬᩍ⫱࣭ಖ⫱せ㡿ࡢྛ⎔ቃ㡿ᇦ
