Contrary to our expectations, females stayed away from territories where males sang elaborately, whereas males were attracted to those territories. Movements of both males and females were associated with male song but not with plumage ornaments. We show that both sexes frequently forayed into others’ territories throughout the breeding period. We used an automated radio tracking system to follow the movements of wild great tits ( Parus major) to other territories in relation to male dawn song, plumage ornaments, and extrapair paternity. Here, we tested how female and male forays are associated with short-range visual and long-range acoustic signals (dawn song).
Yet, whether off-territory foraying is associated with male signals is still not well understood. In territorial species with extrapair mating, female and male forays to other territories may be an important component underlying female choice and male mating success and might be influenced by male advertisement signals. Conspicuous male signals often play an important role in both attracting mates and deterring rivals.
