In laboratory experiments with wild-caught great tits <em>(Parus major),<\/em> we tested the effect of exploratory behaviour (performance in novel food, object and environment test, startle test) on the ability of individual birds to assess the threat represented by a predator. We presented a wooden dummy of the European sparrowhawk <em>(Accipiter nisus),<\/em> an extremely dangerous predator, and its visual modifications (chimeras), changing the beak or head to be non-threatening (those of a pigeon \u2013 <em>Columba livia f. domestica<\/em>). We showed that the differences between \u2018slow\u2019 and \u2018fast explorers\u2019 are not very distinct, but that \u2018slow explorers\u2019 generally tended to be more cautious in the presence of an unmodified sparrowhawk dummy, while the \u2018fast explorers\u2019 tended to observe the dummy. On the contrary, \u2018slow explorers\u2019 tended to treat both chimaeras (and the pigeon dummy as well) as less-threatening than \u2018fast explorers\u2019. Since \u2018slow explorers\u2019 are usually considered to be more sensitive to environmental cues, it came as no surprise that most of them correctly assessed the unmodified sparrowhawk dummy as threatening, while they probably subjected the chimeras to a detailed inspection and were not confused by the presence of sparrowhawk features and assessed them as non-threatening.<\/p>\n<hr \/>\n<h2>Zp\u011bt na\u00a0<a href=\"http:\/\/cke.cz\/publication\/scientific-papers\/\">v\u011bdeck\u00e9 \u010dl\u00e1nky<\/a>.<\/h2>\n","protected":false},"excerpt":{"rendered":"<h2>2018<\/h2>\n<h4><a href=\"http:\/\/cke.cz\/2017\/05\/30\/jaja-nacarova\/\">Jana N\u00e1carov\u00e1<\/a>, <a href=\"http:\/\/cke.cz\/2017\/05\/30\/petr-vesely\/\">Petr Vesel\u00fd<\/a>, <a href=\"http:\/\/cke.cz\/cs_CZ\/2017\/05\/30\/roman-fuchs\/\">Roman Fuchs<\/a><\/h4>\n<h3><a href=\"https:\/\/www....\n<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[18],"tags":[],"_links":{"self":[{"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/posts\/1767"}],"collection":[{"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/comments?post=1767"}],"version-history":[{"count":3,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/posts\/1767\/revisions"}],"predecessor-version":[{"id":1770,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/posts\/1767\/revisions\/1770"}],"wp:attachment":[{"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/media?parent=1767"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/categories?post=1767"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/cke.cz\/cs_CZ\/wp-json\/wp\/v2\/tags?post=1767"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
