For such endangered species, ex-situ conservation plays a vital role, and introducing enrichment in captive environment is important in prompting natural behaviors.  However, only a few enrichment studies have been done on this species, and none in Japan.  An enrichment proven to be effective for sun bears in a study done in Germany requires big outdoor enclosures that is difficult to recreate in most zoos.  This study devises a new feeding enrichment for sun bears, with minimal space and long-lasting effects.  Two experiments were done.  In experiment 1, a log filled with honey and a buoy with a small hole were placed as a feeding enrichment, and the effects were measured.  In experiment 2, to avoid habituation and to achieve prolonged effect, the buoy was moved after each 3-day observation period.  The experiment was done in Yuki Park Zoo (Kofu), and Toyohashi Zoo and Botanical Park (Toyohashi).  In experiment 1, foraging increased by an average of 17.8% in Kofu, and 24.3% in Toyohashi.  Pacing declined by an average of 42.0% in Kofu, and 18.2% in Toyohashi.  Both log and buoy were proven to be effective in increasing foraging activity and decreasing pacing.  Moreover, in using the enrichment, behaviors such as digging and standing up using both hands to forage was seen, which resembles those seen in wild sun bears.  However, the log’s effect was temporary.  In experiment 2, by moving the buoy, decline of pacing and increase in foraging was seen over time, therefore, achieving prolonged effect.  Foraging activity was also seen 7 hours after the enrichment was placed, indicating that this feeding enrichment’s effect lasts throughout the day.  In conclusion, by moving the buoy regularly, this study developed an effective long-term feeding enrichment within the minimal space.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"2","subitem_description_type":"Other"}]},"item_1_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学農学研究科バイオセラピー学専攻"},{"subitem_text_value":"豊橋総合動植物公園"},{"subitem_text_value":"豊橋総合動植物公園"},{"subitem_text_value":"豊橋総合動植物公園"},{"subitem_text_value":"甲府市遊亀公園附属動物園"},{"subitem_text_value":"東京農業大学農学研究科バイオセラピー学専攻"}]},"item_1_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department
