Abstract Seasonal patterns of bird song have been studied
intensively with a focus on individual males. However, little
is known about seasonal patterns of singing during vocal
interactions between males. Vocal interactions have been
shown to be important in sexual selection as males may
signal aspects of motivation or quality. Here, we investigated
in nightingales (Luscinia megarhynchos) whether a male's
behaviour in vocal interactions at different stages of the
breeding season is influenced by its mating status. We
examined how males that differ in their subsequent mating
success respond to a non-interactive, nocturnal playback
presented during the period of mate attraction and subse-
quently during the egg-laying period. We found that mated
males overlapped fewer songs and had a lower song rate
