All bird species which maintained their populations in 1982 and 2007 were detected and each population were estimated not to have declined since then. Dense grows of bushes composed of shrubs and tall herbal plants have developed at the high altitude area (>500m in elevation), and breeding densities of petrels have declined in such habitat. While breeding of Bannerman’s shearwater Puffinus bannermani had been detected around the summit in 2007 survey, it was also found at rocky area at low altitude area (300m in elevation). We found matured and immatured individuals of Tristram’s storm-petrels Oceanodroma tristrami around the top of the mountain, which were the first evidence of breeding of this species on the island. Densities of seabirds breeding were higher at forest habitats in montane area and at habitats with well-developed vegetation in coastal area. We found a breeding colony of Red-footed booby Sula sula above a tall cliff at the southern coast using unmanned aerial vehicle (UAV) which was the first record of its colony in Japan. We also found that some Brown noddies Anous stolidus were found landing on the ground in a small community of Crossostephium chinense above another cliff at the northern coast with UAV, which is possibly breeding there.","subitem_description_type":"Abstract"}]},"item_16_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"postprint","subitem_description_type":"Other"}]},"item_16_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"首都大学東京小笠原研究委員会"}]},"item_16_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_16_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"ISSN"}]},"item_16_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川上, 和人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 創"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"堀越, 和夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川口, 大朗"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-13"}],"displaytype":"detail","filename":"20001-044-010.pdf","filesize":[{"value":"4.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20001-044-010.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/7255/files/20001-044-010.pdf"},"version_id":"4e69dbc9-61a2-47a1-a1a4-110edb59fd41"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ウミツバメ","subitem_subject_scheme":"Other"},{"subitem_subject":"海鳥","subitem_subject_scheme":"Other"},{"subitem_subject":"小笠原諸島","subitem_subject_scheme":"Other"},{"subitem_subject":"火山列島","subitem_subject_scheme":"Other"},{"subitem_subject":"ミズナギドリ","subitem_subject_scheme":"Other"},{"subitem_subject":"Ogasawara Islands","subitem_subject_scheme":"Other"},{"subitem_subject":"seabird","subitem_subject_scheme":"Other"},{"subitem_subject":"shearwater","subitem_subject_scheme":"Other"},{"subitem_subject":"storm-petrel","subitem_subject_scheme":"Other"},{"subitem_subject":"Volcano Islands","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2017年における南硫黄島の鳥類相","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2017年における南硫黄島の鳥類相"}]},"item_type_id":"16","owner":"3","path":["1642"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"7255","relation_version_is_last":true,"title":["2017年における南硫黄島の鳥類相"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T16:19:30.448404+00:00"}
