Little is known about birds, even though some species like ravens have recently received attention for their socio-cognitive skills and use of social bonds. While raven breeders defend territories year-round, non-breeders roam through large areas and form groups at food sources or night roosts. We here examined the fission-fusion patterns of non-breeding ravens over years, investigating whether birds meet repeatedly either at the same or at different locations. We combined four large datasets: presence-absence observations from two study sites (Austria, Italy) and GPS-tracking of ravens across two study areas (Austria, France). As expected, we found a highly dynamic system in which individuals with long phases of temporary settlement had a high probability of meeting others. Although GPS-tagged ravens spread out over thousands of square kilometres, we found repeated associations between almost half of the possible combinations at different locations. Such a system makes repeated interactions between individuals at different sites possible and likely. High fission-fusion dynamics may thus not hinder but shape the social complexity of ravens and, possibly, other long-term bonded birds.</dcterms:abstract> <dc:creator>Itty, Christian</dc:creator> <dc:contributor>Genero, Fulvio</dc:contributor> <dcterms:title>Fission-fusion dynamics over large distances in raven non-breeders</dcterms:title> <dcterms:isPartOf rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:creator>Bugnyar, Thomas</dc:creator> <dc:contributor>Itty, Christian</dc:contributor> <dc:creator>Genero, Fulvio</dc:creator> <dc:creator>Schuster, Richard</dc:creator> <dc:contributor>Bugnyar, Thomas</dc:contributor> <dc:language>eng</dc:language> <dc:contributor>Marchand, Pascal</dc:contributor> <dc:contributor>Loretto, Matthias-Claudio</dc:contributor> <dc:creator>Marchand, Pascal</dc:creator> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:rights rdf:resource=""/> <dcterms:issued>2017</dcterms:issued> <dcterms:available rdf:datatype="">2020-06-23T08:07:05Z</dcterms:available> <bibo:uri rdf:resource=""/> <dspace:hasBitstream rdf:resource=""/> <dcterms:hasPart rdf:resource=""/> <dc:date rdf:datatype="">2020-06-23T08:07:05Z</dc:date> </rdf:Description> </rdf:RDF>
