Abstract
Male American redstarts (Setophagna ruticilla) exhibit two modes of singing : repeat and serial mode. Repeat mode consists of repetitions of a single s ong type, usually one possessing an accented terminal note. Serial mode is constituted by a series of different songs with unaccented terminal notes, sung in a versatile sequence. Different authors have observed that males di scriminate between these two modes. In the experiments reported in this pap er, we tested whether males use accented terminal notes, song versatility o r both to discriminate between the two song modes. We observed that males r esponded more intensively to the accented song. The accented note seems a v ery important song characteristic for evoking male American redstart respon ses. In contrast, males did not show any difference in their response to si ngle and varied serial songs.
