The house sparrow (Passer domesticus) is a small passerine known to be highly sedentary. Throughout a 30-year capture–mark–recapture study, we have obtained occasional reports of recoveries far outside our main metapopulation study system, documenting unusually long dispersal distances. Our records constitute the highest occurrence of long-distance dispersal events recorded for this species in Scandinavia. Such long-distance dispersals radically change the predicted distribution of dispersal distances and connectedness for our study metapopulation. Moreover, it reveals a much greater potential for colonization than formerly recorded for the house sparrow, which is an invasive species across four continents. These rare and occasional long-distance dispersal events are challenging to document but may have important implications for the genetic composition of small and isolated populations and for our understanding of dispersal ecology and evolution.

Funding Information:
We would like to thank the inhabitants of our study area for their great hospitality over more than 30 years of study. Moreover, we thank the large number of scientific staff, students, and volunteers that have contributed to the fieldwork. We thank the Ringing Schemes in Scandinavia for providing updated information on their dispersal records for the house sparrow: H\u00E5vard Huseb\u00F8 at Stavanger Museum, Norway; Thord Fransson at Naturhistoriska riksmuseet, Sweden; and Amanda Johannisson at Statens Naturhistoriske Museum, K\u00F8benhavns Universitet, Denmark. This research was carried out with permissions from the Norwegian Environment Agency and the Ringing Centre at Stavanger Museum, Norway. This study was partly funded by the EU Commission METABIRD, Norwegian Directorate for Nature Management, the Research Council of Norway (Centres of Excellence scheme to CBD project no. 223257, and project nos. 274930 and 302619), and Advanced Grants from the European Research Council (project nos. 268562 and 101095997).
