Abstract

I tested the Rufous-and-white Wren (T. rufalbus) for discrimination between the songs of neighbor and stranger conspecifics. I found significant differences in behavioral responses between the song playbacks of neighboring and unfamiliar conspecifics in seventeen pairs of the Rufous-and-white Wren. Birds sang for longer periods and sang more songs in response to playbacks of strangers. However, the amount that they approached the playback source did not differ between the song types. These results suggest that Rufous-and-white wrens recognize the songs of neighbors and identify the individuals as less threatening than strangers. This diminished response may be an adaptive strategy to reduce the energy spent in territory defense. Wrens do not differentially approach the song source because this behavior is not a primary territorial defense strategy. Yo probé la habilidad del Soterrey Rufo y Blanco para discriminar entre los cantos de los soterreses vecinos y los cantos de los soterreses desconocidos. Encontre diferencias en las reacciones entre los cantos de los vecinos y los desconocidos en diecisiete parejas del Soterrey Rufo y Blanco.
