    Summary
    Male wood warblers preferred to set up breeding territories near conspecific males, which we experimentally simulated with song playback. Pairing rates and reproductive performance did not differ between experimental plots with and without song playback, but fewer eggs survived to produce young on song plots. Additionally, because consequences of artificial attraction for distribution and settlement of the wood warbler remain unclear, acoustic attraction as method for songbird conservation has to be further evaluated.
