However, there have been only a few studies of sexual selection on multiple ornaments. We investigated sexual selection on two ornaments, plumage coloration and white spots in the tail, in a population of Barn Swallows Hirundo rustica gutturalis in Japan. There was sexual dimorphism in throat coloration and in the size of the white spots in the tail. Males with a less saturated (colourful) throat and larger white spots in the tail bred earlier than others, indicating a mating advantage for these males. These trends are what would be expected if these ornaments were indeed sexually selected.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/118020"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本鳥学会"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2326/osj.9.141","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Ornithological Society of Japan 2010"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-0558","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11616388","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hasegawa, Masaru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arai, Emi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Mamoru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Masahiko"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-25"}],"displaytype":"detail","filename":"OS_9_141.pdf","filesize":[{"value":"527.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"OS_9_141.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/28040/files/OS_9_141.pdf"},"version_id":"bfc35b61-cd87-4623-a787-371cf3ef7907"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mating advantage of multiple male ornaments in the Barn Swallow Hirundo rustica gutturalis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mating advantage of multiple male ornaments in the Barn Swallow Hirundo rustica gutturalis"}]},"item_type_id":"5","owner":"1","path":["869","1367"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-05"},"publish_date":"2012-12-05","publish_status":"0","recid":"28040","relation_version_is_last":true,"title":["Mating advantage of multiple male ornaments in the Barn Swallow Hirundo rustica gutturalis"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-04-27T08:55:56.681634+00:00"}
