We investigated whether partners would either maintain contact or offset this risk by exploiting sex-specific favourable niches during winter in a migratory monogamous seabird, the southern rockhopper penguin <i>Eudyptes chrysocome</i>. Using light-based geolocation, we show that although the spatial distribution of both sexes largely overlapped, pair-wise mates were located on average 595 ± 260 km (and up to 2500 km) apart during winter. Stable isotope data also indicated a marked overlap between sex-specific isotopic niches (<i>d</i><sup>13</sup>C and <i>d</i><sup>15</sup>N values) but a segregation of the feeding habitats (<i>d</i><sup>13</sup>C values) within pairs. Importantly, the tracked females remained longer (12 days) at sea than males, but all re-mated with their previous partners after winter. Our study provides multiple evidence that migratory species may well demonstrate pair-wise segregation even in the absence of sex-specific winter niches (spatial and isotopic). We suggest that dispersive migration patterns with sex-biased timings may be a sufficient proximal cause for generating such a situation in migratory animals.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mates but not sexes differ in migratory niche in a monogamous penguin species","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-25 01:32:14.640694","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"pair bonds; winter; monogamy; geolocation (GLS); seabird; stableisotopes","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2020-06-24","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000364772300005","VABBcode":null,"OpenAcc":0,"DOI":"10.1098/rsbl.2015.0429"},"refs":null,"anarec":{"AnaID":256880,"PubliDate":2015,"Pagination":"20150429","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":110806,"SerRR":"Biology Letters.
