We aimed to identify the existence of age-classes groups that shared similar seasonal patterns in migration movements for the lesser black-backed gull Larus fuscus. The gull age-classes groups were defined as sets of age-classes that were present in the harbour of Malaga (South of Spain) simultaneously during the wintering season. We distinguished ten groups of age-classes, which can be subsequently lumped into four big age-class groups: (i) immature stage-class, (ii) young breeders, (iii) age-classes from 6 to 11 years old, and (iv) age-classes older than 11 years old. Our present results supported the 'dominance and arrival time model'. 1
