You have the male singing up here at G, and you have the female singing down here at D, and when they get together, you're saying that they change the frequency of their wings such that they come together?
¿Tienes al macho cantando aquí en la G y a la hembra cantando aquí en la D, y cuando se unen, dices que modifican la frecuencia del batido de las alas de tal manera que se alinean?
