Hatching vocalisation rates (in number per minute) were not consistently influenced by ambient air temperature. They did not differ between chicks hatching from first-laid eggs (which are smaller, hatch second, and usually suffer brood reduction) and chicks hatching from second-laid eggs (which usually develop into fledglings). Hatchlings did not show significantly different vocalisation rates in the presence of a sibling during hatching. Hatching vocalisation rates also did not increase between the penultimate day and the last day before hatching. These results suggest that Rockhopper Penguin chicks might gain little benefit (parental care) from increased vocal behaviour at the late incubation stage.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Hatching vocalisations in free-living Rockhopper Penguins","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Rockhopper Penguin; hatching vocalisation behaviour; egg dimorphism; airtemperature","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2014-06-20","DateCreate":"2014-06-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000320894100006","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":239244,"PubliDate":2013,"Pagination":"39-44","XtraPublOfAnaID":null,"ISBN":null,"Volume":"101","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45416,"SerRR":"Ardea.
