There are few studies conducted on their calls, even though this species produces loud calls.  A previous study suggested that they have several call types, for example, the “Gururu” exchange call and the “Kyokyo” call used in alarm and mating contexts. “Gururu” calls were divided into five subtypes ; however, this classification was subjective and dependent on the researcher.  We classified the calls of the Japanese giant flying squirrel at Mt. Takao in Tokyo and Daiyuzan in Kanagawa Prefecture, Japan using objective statistical methods such as principal component analysis (PCA) on six measurements : peak frequency, duration of the note, duration of the call bout, inter-note interval, number of pulses, and number of notes.  PCA results indicated that the “Gururu” calls were not clearly distinguished between the natural calls and the response call, whereas the “Kyokyo” calls were distinguished with the first axis explained by the number of pulses and note duration, and the second axis explained by the number of notes and call duration.  This suggests that the “Kyokyo” call can be classified into two subtypes, along with a sound character and context (alarm and mating).","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":"東京農業大学農学部バイオセラピー学科/三重大学生物資源学研究科生物圏生命科学専攻"},{"subitem_text_value":"東京農業大学国際食料情報学部国際農業開発学科"},{"subitem_text_value":"東京農業大学農学部バイオセラピー学科"},{"subitem_text_value":"東京農業大学農学部バイオセラピー学科"},{"subitem_text_value":"東京農業大学農学部バイオセラピー学科"},{"subitem_text_value":"東京農業大学農学部バイオセラピー学科"},{"subitem_text_value":"東京農業大学農学部生物資源開発学科"}]},"item_1_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department
