摘要

The role of chip calls in the winter territoriality of Yellow Warblers (Dendroica petechia) was studied in the Republic of Panama. There was extensive variation through the day in chip rates and time spent chipping, with vocalizations greatest in the morning (0630- 0830 h) and at dusk (1730-1830 h). A bout of rapid chipping at dusk was observed in several birds. Individuals responded aggressively to playbacks of chip calls by increasing chi rate and flying close to playback speakers.
