We investigated the wintering distributions and migratory flyways use of geographically contiguous populations of Lesser Black-backed Gulls (<jats:italic>Larus fuscus<\/jats:italic>) and difference in population winter age structure between migratory flyways. Recoveries of metal ringed pulli from Denmark, Sweden, and Finland were used. The results showed that contiguous populations can have distinct wintering distribution patterns and migratory flyways. More importantly, we found that depending on the place of origin, the population winter distribution may or may not show a latitudinal cline in the age structure. The population migrating via the eastern Atlantic flyway (western flyway) showed a winter age-related latitudinal cline, with adults staying at more northern latitudes than immatures. In contrast, no such pattern was found in the population migrating along the Mediterranean\/Black sea flyway (eastern flyway). Interestingly, immatures within the eastern population showed a more dispersed pattern of migratory bearings. Overall, our results enhance the importance of the migration flyway in shaping the age structure of populations in the winter quarters and how it may influence the effect of other factors like sexual maturation.<\/jats:p>","DOI":"10.1155\/2013\/737616","type":"journal-article","created":{"date-parts":[[2013,12,8]],"date-time":"2013-12-08T21:01:47Z","timestamp":1386536507000},"page":"1-7","source":"Crossref","is-referenced-by-count":2,"title":["Winter Latitudinal Population Age-Structure of a Migratory Seagull (<i>Larus fuscus<\/i>) Differs between Its Two Major Migratory Flyways"],"prefix":"10.1155","volume":"2013","author":[{"given":"Paulo A.
