Abstract

The communication between organisms has long been a fascination of mankind. Birds have been the subject of many such studies as they commonly have a large repertoire of communication techniques. This study examines the changes in several song measurements in order to determine the vocal responses of the breeding pairs to playbacks of various con-specifics. The researcher found that using measurements of low, high, center, maximum, and delta frequency of each pair before and after a playback, the pairs were easily differentiated from one another (Wilks != 0.61629, F20.455=3.57, p<0.001). Following playbacks, all pairs evaluated showed a decrease in maximum frequency of song phrases and a narrowing of frequency ranges (smaller delta frequency). Such changes in song characteristics may function to make the singing pair sound larger to intruders or to decrease call interference and the distance that the call travels. La comunicación entre los organismos ha sido desde hace mucho tiempo de interés para la humanidad. Las aves han sido un tema de estudio en este campo debido a su gran variedad de repertorios utilizados para la comunicación. En este estudio examine los cambios en varias medidas de las vocalizaciones para determinar la respuesta vocal de las reproducciones de las parejas de varios conspecíficos.
