ABSTRACr.-We have demonstrated that male hummingbirds in the genus Colibri share song types. The Sparkling Violet-ear (C. coruscans) from an Ecuadorian population and Green Violetear (C. thalassinus) from populations in Costa Rica form aggregates or neighborhoods. Males of a neighborhood sing the same song type and those of distant neighborhoods have different song types. The resultant geographic variation in song, we suggest, is due to cultural drift acquired through song learning. Song… CONTINUE READING
